So I bought a Used 2002 TJ Sahara 2 weeks ago, and with it came a bumper to bumper 30 day warranty. Everything seems clean, and runs great. However, before this so called warranty expires, I want to take it to my mechanic to have him check a few things, before i take it back to the dealership, but instead of being the guy that says "it makes a noise", what are some key items I should have checked?
The reason I ask is because lately, i have narrowed down two items that make noises. I am aware that Jeeps are notorious for their clicks, and squeaks, and groans, but 2 i am concerned about.
1) Highway driving is great, smooth, no shakes or shimmies, but when i start hitting bumps, or uneven terrain, i start hearing bangs. I have been able to replicate the issue with the banging. When i have the wheel turned to make a left turn, if i hit a bump, a loud bang occurs from somewhere up front, like something large is lose. I have looked under, cannot find any wear or tear, rubbing, chipping of paint, or any of that sort. The only thing i can find is some wet spots by the U-joints from the left front axle where it connects to the left tire assembly. (forgive my lack of terminology) I definitely noticed this knocking sound when I had it in 4Hi while i was "testing" the 4wd in some muddy terrain last week, since then i have been keeping an ear out. I noticed it before hand as well. Cannot tell a difference in handling other wise.
2) When I back up, or go forward, at a slow speed, it feels, and sounds, like rubbing from the rear end. I have 31x10.50s , BFG All Terrain and cannot find any rubbing at all. I even had my uncle hang up-side down to verify while moving forward and backward. Kind of like back in the day when kids would put playing cards in the spokes of their wheels. Its more obvious when the wheel is turned in either direction, but I cannot always replicate the issue on demand. Wheel does not have to be cranked all the way over either.
I have searched the forum for a variety of terms for both issues I have described, and couldn't really come to a solid conclusion as to what it may, or may not be. Maybe someone out there can think of something.
The Jeep currently has 78,000 miles and some change.
