Hello, I'm new on here and I hope someone can help me with my new 6 inch lift I have installed on my 2004 WJ Grand Cherokee Overland. I would like to stay at 6 inches so I don't have to cut out my fenders and clear the 33" tires and 18 inch wheels that I bought brand new and have on it. I have already trimmed my front bumper so it is ok. I will be driving it on the highway mostly to and off-road some maybe. The parts I have and installed are a front JKS Adjustable track bar, rough country 4" drop pitman arm, rear addco 1" sway bar, IRO extended sway bar links, Bilstein Shocks, 4" Teraflex coil springs with 1.75 spacers in front and rear also with two 3/4 rear coil spacers too, Rock Crawler Upper A-arm spacer with 1" offset, IRO 3 Link front high clearance fixed long arms with Rusty's Off-road adjustable rear long arms to with new brackets and cut the original factory ones off for the new long arms. Ok now First problem I'm having is the front suspension and the springs having a curve to them and not straight and hitting the sway bar links on the passenger side. The driver side is not so bad and has the Y Link on the long arm. Could it be because it is not a 4 Link setup? Also the IRO sway bar links I have are for a 4" lift so that could cause a problem to I would think. Another thing is if it would be safer and better to get 6" coil springs I will. Second problem is my driveshaft angles on the front and rear and I have not installed the TC drop because people said it makes the angle worse on the front driveshaft. On the transfer-case the pinion angle is 6 degrees, the rear end it is 9 degrees and the driveshaft working angle is 10 degrees which is not good and will not work as far as driveline vibes. Could i use a TC drop with a multiple Double Cardan Front driveshaft because of the angle? Also anyone on here been able to just lengthen your rear two u joint driveshaft and been ok with no vibes? That's what I was hoping I could do and wanted to ask If it was possible or if anyone on here has done it. If not I will have to go to a double cardan on the rear too. All help is appreciated thanks

First of all, you picked a terrible setup for a DD. Secondly, ditch the drop pitman arm. Since you have an adjustable trackbar, its not needed. Thirdly, you need to adjust your trackbar to center your axle, then adjust your control arms to pinpoint a happy medium between caster angle and pinion angle. At that height, it is going to be difficult to achieve decent caster without driveline vibes.

^ what he said. Also, for the last time, IRO's lift is NOT a 3 link.

First thing I'd do is remove the spacers to reduce a bit of height.

Why do you need that much lift? Even if 6" is needed, purposely stacking spacers doesn't sound like a good idea to me.

There is quite a bit wrong with your setup. Start with what ezflip and skain8 suggested and see where that gets you.

Thank you for the replies to my questions and comments. I went to a 6" lift and higher so I could clear 33" tires without cutting my fenders and thought that was best and bought new 18" wheels and 33" tires. I added 2.5 coil spacers at first because I already had them and saw it was to much, so I bought and went down on the suspension with the crown 1.75 spacers instead and thought it would be ok. Now on the front my spring perch's are tilted so much it's causing the springs to bow forward. I have the front IRO high clearance long arms with angle adjustment only for the caster and pinion angle. In the rear I have Rusty's Off-road adjustable lower long arms. I had to cut all the original factory mounts off so I could use the long arms. How can I get my caster back close to factory specs and correct pinion angle?

You can't get the caster and pinion angles back to factory specs at that lift height without doing surgery on the axle.
Best you can do is a compromise. You want less caster with the larger tires anyhow.
You would be much better off getting a 6 in spring if you want to stay at that height.

Ok does the front differential pinion shaft have to point straight at the transfer case to avoid vibration of the driveshaft?

Pretty much.. a couple deg down in relation to the driveshaft is actually better to allow rotation of the bearings in the u-joint.

It depends on what front driveshaft you have (CV or Cardan). If you search on the forum you'll find your answer on this.

It sounds like your control arms up front aren't adjustable length which is less than ideal for dialing in your front axle location. Basically if you want your front springs to not bow out forward you need to be able to move the axle forward or lose some of your lift.

Stacking spacers is pretty much universally advised against, but I think a spacer on top of a lift spring is ok as long as you can adjust for the height.

I'm really not trying to be a jerk but in all honesty it sounds like you lift was pieced together without much forethought or research.

I have a double cardan front driveshaft and would it help if I had 6 inch coil springs in front and lose the spacers as far as the bowing of the coil springs?

No. And spring bow is the least of your worries.
