Front to Rear lift
Okay, we're jeepers, so many of us are completely up for the "Down and Dirty F=>R"

So what is it?

The coil springs on a ZJ (production years '92-98) are the exact same diameter inside and out on the front coil springs as they are in the rear.

side note: TJ, XJ, and ZJ all use the same diameter inside and out front coil springs.

The front springs on a ZJ are a bit longer, I don't recall how much longer and they are stiffer. Since they are the same diameter inside and out, you can move them to the rear and it will increase the ride height of the rear end of your ZJ Grand Cherokee.

The front coil springs in a V8 ZJ Grand Cherokee are a bit longer and a bit more stiff than those in the I6 4.0L equipped ZJ Grand Cherokee. The springs from the I6 will not give you the lift you are looking for.

There was a package called "Up-Country" that lifted the ZJ .5"~1" higher than a normal stock height ZJ Grand Cherokee. You can also use this spring as it is even longer and again, a bit more stiff than the normal V8 Spring.

This is all from memory as it has been over 3 years since I had my ZJ, but I do remember this:

UC = Up Country

V8 UC Front Springs when moved to the rear: ~4" of lift
V8 Normal Front Springs when moved to the rear 3"~3.5" of lift

I used Rancho shocks RS5000 shocks all the way around with Rancho 3" springs in the front and normal V8 springs in the rear and added in about 1" spacers for 4.25" of lift in the rear and about 3.75" of lift in the front.

You'll need longer sway bar links front and rear. This really helps to control body roll.

The total cost? About $100 for the Rach Springs. $45 for the V8 springs if you don't already have a V8. Shocks are $35 each.

You may need a rear adjustable track bar or track bar bracket to recenter the rear axle. The front axle though shifted, was not enough to need a different track bar. Adjustable Track bar was around $140? I think.

You can run your stock shocks till they separate on you if you'd like, but I'd recommend replacing your shocks at the same time.

So, total you are looking at about $340~$450.

Plenum Gasket writeup
The weekend of the 14th (Jan í06) I decided to tackle the Plenum Gasket for the 5.2L. Others and I noticed the bluish tint of burning oil in my exhaust especially during wheeling. You can see what Iím talking about in the second badlands video. I also noticed some oil comsumption based on level. Reading up on it revealed that is it a common issue with higher mileage Dodge/Jeep magnum engines. (I have 174,xxx on the clock right now) The write up by Dr. Righteous on JU ( helped tremendously! Iím not sure I would have attempted it without it. The Haynes leaves some areas that are important a little fuzzy. Yes this was difficult. I am by no means a mechanic so this might very well be a breeze for the seasoned professional. Would I do it again? I hope I donít have too, but I would always lend a hand to someone who wants to wrench.

Some tools / supplies that you want to get your hands on:
(not pictured)
-You will need a basic socket wrench set, SAE and metric, deepwell and shallowwell sockets, extensions etc.
(pictured below)
-Torque Wrench in INCH-POUNDS (in-lbs) very important!
-RTV gasket (I used Napa ďRight StuffĒ it was what I had on the shelf)
-Air nozzle attachment
-Fuel line disconnect tool (the small plastic circle sets work well too)
-Air hammer
-Magnetic extension (for fishing out the things you drop into the smallest of places)
-Stubby 22mm wrench for EGR tube (any longer and it will not fit!)
-Nice small, yet bright flashlight to compliment any other overhead light source
-Wire wheel (to clean mating surfaces)
-Compressor to run the air tools

The fan has to come off. There is a big 36mm nut (1 7/16) that needs to be loosened while holding the pulley still. I didnít have a 36mm wrench so I used a vise grip. I also didnít have a spanner wrench that you can use to hold the pulley still (thinking you can hold it still with the belt and apply the force needed to break the nut loose is a joke!). Unfortunately I didnít get a picture of this but I removed the four bolts that held the pulley to the mount (the mount freely rotates with the pulley) and was able to get the air-hammer on the mount. I held the vise grip tight and feathered the trigger on the air-hammer until I broke it loose.

Some Tips:

When removing the accessory bracket in front, there is one bolt hiding behind the idler pulley. Use different zip-lock bags to store all your bolts.

Once the fan and fan shroud were removed I put a piece of cardboard up against the radiator. Iím known to drop tools and other things and I didnít want anything to gouge the fins. Yeah I know radiators can be tough, but it was something that took me 3 seconds to do and it gave me some security incase I did something dumb.

Label your injectors. They look identical and need to be put back in the correct configuration. I used a silver and black sharpie marker to label items, you can use whatever method works.

I strung a bungee cord low across the underside of the hood near the engine. I used some wire to string up the main wiring harness while working under there.

I did a tune up while the intake was off. It will be the easiest tune up you will ever do. The distributor cap / rotor are EASILY accessible during this part of the procedure. I removed the rest of the oil-pressure sensor I broke when I was wrenching off the EGR tube.

I strung a bungee cord low across the underside of the hood near the engine. I used some wire to string up the main wiring harness while working under there.

Once you remove all 12 bolts holding the intake on, make sure everything is disconnected and you can pull the intake off. I stuffed shop towel in the cylinder intakes and over the holes over the camshaft in the bottom of the lifter gallery once I cleaned it out. Dropping something down in there could ruin your day, whether you knew about it then or if you didnít know and it damaged things later. When you are starting to reassemble, make sure you put the lifter guide retainer on the outside of the lifter guides.

Here is a picture of most of the things I replaced just because or because I broke them! :D

Top is the heater bypass hose. (Napa P/N = 8722 )
Below is the throttle body gasket. (Napa P/N = G31527 )
Top right is the 195* thermostat and gasket (Napa P/N = 269)
Middle is the temperature switch (Napa P/N =TS6682 ) Make sure they give you the one with only one terminal pin inside, in the Napa computer the temp switch and temp sensor had the same part number, however the boxes they come in are correct. The temp sensor has two terminal pins.
Right is the Oil Pressure sensor. They DO break easy! (Napa P/N = OP6695SB )

I lost the P/N for the actual gasket set. I used the Felpro gaskets from Autozone. It comes with the plenum pan gasket, the front and rear cork gaskets, and the two manifold / intake gaskets.

I also replaced my PCV valve when I broke that off by accident.

When you are at the parts store, grab some ľĒ ID (inside diameter) rubber vacuum hose. Helps when some of the old lines break.

More writeup
Use proper torque specs, tightening order, and tightening steps! This is very important, if you do not follow it correctly it, the gasket will not properly seal, vacuum leaks could occur, and your can warp the mating surfaces. So get yourself a quality torque wrench and get to work! The Haynes was a little unclear here, but my mechanic friend Dave helped me out with the proper torque, pattern, and steps. (if you cannot read it there is the larger version in the photobucket account) The numbers in bold print are in-lbs. The numbers in blue hand writing are in ft-lbs.

Here are legible pictures of the torque specs! Sorry! You can put away your microscopes! :D

When reinstalling the intake it is helpful to have some extra hands. Thankfully my friends Blaine and Aron were available to help position, hold wires, and direct, to ensure that the intake was set straight down without moving the pre-places gaskets.

As you can see, I stuffed shop towel into the intake holes where the throttle body sits. I also stuffed some inside the thermostat housing. I just didnít want to take the chance of something falling in there!

Texas ZJ1 01-30-2006 05:41 PM

Even more
Torque the throttle body bolts to 200 in-lbs.


Here is my new bling bling CCV breather. +50.94lbs-ft torque and +35.56 HP (at the wheels!)

About wrenching on the EGR tube: This was the hardest part by far. A standard length wrench will not fit because of the firewall. I needed to run to the store and buy a stubby 22mm wrench (about 6 inches long) just to be able to get a wrench on the nut. The nut is VERY stubborn and less than 6 inches of leverage crammed into a tight space makes things very difficult. With the open end of the wrench on the nut, I was able to put the blunt tip of the air-hammer in the boxed end. I held the wrench with my left hand and feathered the trigger on the hammer with my right.. This method was very controlled and as soon as the nut started to break lose I let off with the hammer and proceeded by hand with the wrench. It still takes a LONG time since you can only get about a 6th of a turn in each time. I didnít get a picture of this exact method, but I set up the wrench in the vise to illustrate what I am talking about.

Change your oil!

Hope this helps anyone in conjunction with Dr. Righteousí write up for fixing the plenum gasket. It was such a relief to finally drive her on the third weekend! :banana:

Note that I did not reinstall the factory fan and shroud. I replaced it with a ford Taurus 2-speed E-fan, look for the details on that later :cool:

3 inch lift write up

Pitman arm joint fix writeup.

From Dr. Righteous

Texas ZJ1 02-05-2006 07:09 AM

Something to think about.
This is from Ron. He couldn't have stated it better.

I'm starting to notice a large influx of newbies inquiring about lifting their jeeps around five to six inches. I'm wondering why you all desire this lift height and what you plan on accomplishing by doing so (ie. what size tires you want to run, specs on your lift/drivetrain, type of wheeling you plan to do).

The reason I ask is because, in my opinion, a 5-6" lift on a grand with short arms and stock axles/driveshafts is a very poor setup. This can be done but, the cost goes up!

Do you want to lift your ZJ 5-6" to fit a specific tire size? Do you realize the consequences on the drivetrain as a result of running that tire size? I'm guessing that most people who want to lift their grands this much are planning on running 33-35" tires, and that lift height/tire size is a wonderful combination that will likely not require excessive fender/bumper trimming and/or rediculously extended bumpstops. HOWEVER... to SAFELY and RELIABLY wheel on 33-35" tires, the axles will need to be regeared (especially if you have a 4.0L w/ 3.55:1 gears), or better yet, completely replaced with stronger axles capable of handling the loads that these bigger tires impose upon them. I swapped out my stock axles because I kept breaking them every time I went wheeling with my 33" tires...and even when my rig wasn't being wheeled, I was going through hubs and balljoints like crazy. I have ~4500$ in axle parts from doing my axle swap, and it would've cost a lot more had I not done all the work myself and made every single little bracket from scratch.

Control arm angles are another thing to consider. Anything above about 4" of lift makes for noticeably steep control arm angles. These steep angles suck because they do not allow the suspension to work properly. As the control arm angles get steeper, their bushings start to become the absorbers of vertical movement of the axle, which is supposed to be absorbed/dampened by the shock absorbers. Also, everytime a bump in the road is hit, the front axle not only travels up as usual, but it's also now forced to travel forward following the arc of the control arms pivoting at the frame...the more severe the CA angles, the more forward movement the front axle is forced to make when a bump is hit. This is not really a factor for the rear axle, as it is forced backwards when it goes up...which is much easier for it to do as the vehicle is traveling forward. Taking note of this should make it easy to understand why steep CA angles result in poor ride quality.

Another thing to think about with a 5-6" lift is poor steering geometry. The inverted "Y" design of the stock ZJ steering works very well at stock ride height since the tie-rod and drag link are relatively close to parallel. As the vehicle is lifted, the tie-rod and drag link become more perpendicular. Due to the geometry of the inverted "Y" steering, the toe of the tires will change significantly when a bump is hit if the two links are not close to parallel. If you can't visualize why this happens, make a quick model of your stock steering with a couple pencils and notice how the ends of the links where the steering knuckles would be move together and apart as the "ride height" changes via the mock pitman arm. The rapidly changing toe angles of the front tires after hitting a bump is a primary source of the dreaded deathwobble.

Have you thought about driveshafts? Odds are good that with 5-6" of lift and stock axles, you will have a very difficult time adjusting the caster of the front axle correctly without introducing terrible vibrations from the front driveshaft. With a double-cardan style front driveshaft, the axle pinion should be pointed directly at the transfercase...if it is not, the driveshaft will likely vibrate like a *****...which will not only annoy the crap out of you, but it will also quickly wear out your driveshaft U-joints, pinion bearings, and transfercase output bearings (these vibrations may also result in female passengers reaching orgasm while riding in your jeep, but we all know the female orgasm is only an urban legend anyway). So since the front axle needs to be close to its stock orientation to maintain decent caster, the pinion will not be able to point at the t-case like it needs to.
The rear driveshaft is not as much of an issue as the front axle if adjustable lower rear control arms are used. Adjustable/longer control arms will allow you to rotate the rear axle back to a "level" (stock) position, and will result in proper d/s angles so that vibrations should be minimal.

There are several other things I could go into detail on, but they're not quite as significant as the issues stated above.
But basically what I'm trying to make a lot of you realize is something I've stated several times before: you can lift a grand to about 4" very easily, safely, and inexpensively...but lifting it the next couple inches is a huge step that opens a huge can of worms that will likely cost you a small fortune.

So if you are a newbie to wheeling grands and are curious about lifting it, I'd strongly recommend you keep it at 4" or less lift and 32" or smaller tires unless you are very dedicated to working on it and wish to spend obscene amounts of money on it to make it drive and wheel properly. Keep It Simple Stupid!

If ya'll don't understand some part of this or need further clarification on anything, or disagree with anything I've written, speak up and I'll gladly address your concerns.
