Spark Plugs

It is generally accepted that Jeeps perform best with OE-type Champion brand spark plugs, regular cheap copper core plugs. Some people have good results with other types, but more often than not people wind up changing back to the simple, cheap Champion plugs.

Here are the part numbers and stock numbers for the plugs you need. Many stores will use stock number instead of part numbers to look these up.

4.0L: Champion #RC12ECC Stock #438, Gap .035"
4.7L: Champion #RC12MCC4 Stock #439, Gap .040"
4.7L HO: Champion RC7PYCB4 Stock #3340, Gap .040" - this is a fine-wire platinum-tipped plug. Chrysler advises that use of any other plug can cause damage to the engine.

The Champion Truck Plugs are an inexpensive "upgrade" plug for 4.0L and 4.7L owners. They have a 20% thicker copper electrode and a stronger ceramic insulator so they should last a little longer under heavy load conditions. They usually cost about $1 more than the standard and in my opinion they are a good buy.

Part numbers:
4.0L: Stock #4412, or Stock #7034 (superceded)
4.7L: Stock #4071, or Stock #7071 (superceded)
4.7L HO: N/A

[edit] - Champion seems to have superceded their copper truck plugs with double-platinum truck plugs and tripled the price. If you can't get the copper ones, don't bother.

Spark Plug Replacement 4.0L

Spark Plug Replacement 4.7L + 4.7L HO

here is what i remember off the top of my head. i know i a have a few more like adding a, flasher relay repair, tail light repair, small emission leak help,

dual control blen dor no dash remove install writeup with pics
http://www.jeepforum.com/forum/f13/d...p-pics-884932/
has info on the new kits as well

++++++++++++++++++++++++++++++++

info on how to replace TC output shaft seal

mopar part number is 4897298AA for the 247 SEAL, rear OUTPUT SHAFT.

1) drive the rear of jeep up on a ramp and chock the front tiers
2) put on the parking break on, because I will have to remove the rear drive shaft and "park" does not work when the drive shaft is disconnected.
3) Drain transfer case fluid
4) mark the line across the pinion yoke so it will be installed right later, then Remove rear drive shaft and slide it out of the t-case output. oil might leak out so keep a oil pan near by and keep the TC output shaft for getting dirty or damaged.
5) The old seal is now exposed. Hook it with a "seal puller" tool and pry it out of there. Careful you are prying on the seal and not digging into the aluminum inside the housing. It should come out somewhat easily.
6) Tap the new seal in place. You can do this easily with just a rubber mallet and block of wood
7) Re-install drive shaft. Careful there is no dirt on the surface that is to seal with the t-case.
8) fill the TC with new fresh fluid

if its a 247 only use fluid form the dealer

+++++++++++++++++++++++++++++++++++++++++++++++

PS hose leak on 4.7
4.7L Hydraulic Power Steering Hose is a dealer only part
part number 5019708AE http://www.justforjeeps.com/01grch4hypos.html

also need the right fluid from the dealer MS9602

+++++++++++++++++++++++++++++++++++++++++++++++

add a 3.5mm aux jack if you have a cd changer, cost under $10

-from radio shack pick up item # 274-0246 which is A 1/8" Stereo Panel-Mount Phone Jack $2.71 with tax (NY) http://www.radioshack.com/product/in...ductId=2103451
- need a 3.5mm male to 3.5mm male cable to connection your device to the jack. i found one at a 99 cent store for $1.08 with tax http://www.topchinashop.com/images/AUD-014.jpg
-Then get seem basic stereo wire or even 18 gauge wire and finger out were you to mount the 3.5mm jack.
-Cut 4 cables the same lengthen that it take to get from were you want the jack to the back of you head unit and leave some play room and one other cable for the ground
- Remove the cover around the head unit and the head unit http://wjjeeps.com/interiortrim.htm#RADIO
- following the schematic http://wjjeeps.com/radio_cdch_cable1.jpg you have to find audio out left and right which is 1 & 5 on 8 pin side and 1 & 6 on the 10 pin side
- since the 10 pin side is going to the head unit we will use that one, so cut wires 1 & 6 left and right audio
- then you wire it up like this http://i782.photobucket.com/albums/y...schematic2.jpg

line 1 that goes to head unit connect to pin 2 on the 3.5 mm jack
line 6 that goes to head unit connect to pin 5 on the 3.5 mm jack
line 1 that goes toward CD changer connect to pin 3 on the 3.5 mm jack
line 6 that goes toward CD changer connect to pin 4 on the 3.5 mm jack

- ground the wire going to 1 on the 3.5mm jack to the body or pin 7 on the 10 pin side
-tape it good or shrink wrap

when you select the CD change and plug something to the 3.5mm jack it will play what is connect to the 3.5mm jack. when you unplug the jack it will go back to playing the CD.

Here's a complete parts fiche for the 2001 WG Grand Cherokee. Not PERFECT and some of the info is not pertinent to US models, but it is helpful for seeing exploded views of systems and is 99% correct for OEM part numbers.

We don't have TWO digit codes like in that thread, and WJJEEPS.COM has a page that has all the codes...

Good call on the state laws though

What is the largest tire I can run on my WJ without a lift?

16" wheels:
245/70-16 (29.6")

17" wheels:
245/65-17 (29.5")

Slightly larger tires such as 245/75-16 or 255/65-17 can work with minor rubbing and/or trimming of fender liners/front bumper.

Your results may vary depending on tread depth, wheel backspacing, and suspension condition.

If you are lifted and have the same question, see the handy-dandy chart over there on page 1.

Perhaps some Google.com search tips. The JF search feature will not search for anything less than 3 characters, i.e. WJ. However, you can with google.

If you specifically want to search JF enter the following in google:

site:jeepforum.com enter you search criteria here i.e. wj bb tire size

You can get even more specific with your search site by:

site:jeepforum.com/forum/f310 enter search criteria here

This will ONLY search the WJ section of JF.
