Just got a 2002 GC!
I just got a used 2002 GC Laredo for cheap!
Just got it last night so I will go over the whole car this weekend.
What would you guys recommend I should do as my first maintenance/clean up on the '02 WJ?
Obviously I plan to swap the fluids and all that, anything else you would recommend I look for that may be questionable on a used WJ?
Thanks guys,

What engine, t/case, and mileage are we talking about? The differences between the 4.0 I6 with the Selectrac and the 4.7 V8 with Quadratrac II are immense.
Usually when someone says "cheap" I wonder what's wrong with it.

Doesn't slip but I'll change fluid anyway.
Oh, around 300k on the odometer haha

Okay. that explains a lot! The 4.0 I'm not concerned about. They are pretty reliable and long lived. Also, with the 2WD, you're not pulling the weight of a 4WD. My '00 WJ weighs 3970 lbs registration curb weight. Yours doesn't have the weight of the t/case and front axle which is considerable.
My major concern is the transmission. At 300K, it's well worn, even with 2WD. That's a lot of miles on a 42re, but if it's been taken care of should last a while. Just don't go pounding on it. Of course, this is immaterial if it's been rebuilt already. I would suspect it has.
One thing I have noticed. The driver's seat left side bolster tends to collapse from getting in and out. This seems to be a problem with all jeeps but is more noticeable with the WJ because of the added lateral support of the seat design.
Pay particular attention to the rear axle wheel bearings, ring and pinion gears, and pinion bearings. The D35 axle is not the strongest kid on the block and tends to start whining around 150K. This seems to be more if a problem with 4WDs that are driven in 2WD most of the time.
I would suggest changing and bleeding your brake fluid. This is something most people forget and can result in internal corrosion in the master cylinder and calipers. Brake fluid is "hygroscopic" meaning it absorbs water. It's the water that ruins the system.
Check your wiring for corrosion in any external plug connectors. a lot of the sensors work on 5 volts so connections need to be clean and bright. Pay particular attention to the 02 sensor wires where they pass the exhaust pipes.
That should keep you busy for a while.

I'll poke around the jeep this weekend and let you know what I find.
Thanks a ton

I'm always willing to share information. If I'm not sure about something, I'll tell you so. Besides, there are other people with other opinions that I'm sure will correct me if I'm wrong.

Only had a little time this weekend to mess with the wj.
Seat bolster is definitely degraded, I'll be driving daily so will need to fix that.
Probably some wiring issues, window controls don't work unless the driver side passenger switch is pressed, then everything on the master window control switch works well. All window regulators have been replaced.
Tranny fluid/filter will be changed next week, fluid looks a little dirty (not too dark though).

Check out wjjeeps.com for lots of specific info about the WJs. Even dash light bulb sizes!

Put in your Vin number and get your build sheet. It'll tell you about all the equipment and options that it has from the factory.

Do a prerunner or jeep speed. Never seen a wj made into one. But check all the cv boots and replace them as they tear and leak after a while. Replace worn out bushings.

About the seat bolster. It's just soft foam and the cover comes off pretty easily. It's held on on 3 sides with plastic clip strips and the plastic panel on the door side.

I'm pretty sure auto upholstery shops can help you. I had a leather bucket seat for my Chrysler 300H redone when the seams came apart.
