We bought a 98 ZJ 5.2 4x4 (Quadratrac) w/ 146,xxx miles for a reasonable price and it seamed to have little wrong... BUT...
My First concern is, after having it for about 2 weeks, after driving it (usually after a short run), when I put it in park and turn off the engine, it sounds off a thud/popping type noise and the whole thing will shake as if it were in gear and quickly pumping the breaks. This kinda freaks me out.
Secondly, when turning aprox. 3/4 to full turn, I get a noise like a whining and I get heave resistance that will slow me down to a stop. I do know that I need to replace the driver's side wheel-hub assembly. I have the part, I just haven't put it in yet.
Has anyone else had this problem? May it just be the hub assembly? Or does it sound more of a problem with the Diff?
Lastly, it's more annoying then just being a problem (yet), but I have a leak somewhere, and I can't find where it is coming from. I check the basic fluids (coolant, steering, oil, trans) regularly, and there's no visible signs of a leak. the leak is on the passenger's side of the Jeep and is yellow in color, but no distinguishing smell to it.
Are there any "common" leaks in the 5.2L ZJ's? Ideas on troubleshooting?
I'm sure I will have more questions in the future, but it's a Jeep.... I doubt they'll be any soon.
Cannot help you with first 2 but maybe the last. I pulled my window washer fluid reservoir the other day when replacing my shocks. Then I set it up on the fender and jacked up the driver side I noticed a puddle of green fluid behind front passenger tire. I freaked out thinking it was anti freeze but no smell and then noticed my window washer fluid tank was nearly empty.
There must be an overflow or pressure relief on the passenger side????? Hopefully that is the source of your leak. BTW no leak before or after I reinstalled the tank and fluid to all three nozzles.
Your second problem sounds similar to mine. When I try to make a sharp-ish turn, my Jeep has a lot of trouble doing it. It bounces, is loud as hell, and needs more gas to keep moving. If that's the case for you, it's the viscous coupler. I just kinda deal with it, and plan on swapping in a 242 or 231 when I get the chance and money to.
