Problems with buying used... Please help
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.
