I've just started to have some problems with my Jeep (2005 TJ Unlimited, 6 speed manual, 4.0 L, 100K miles) that I'm not too sure what to do with.
First: it squeeks in reverse. This doesn't happen EVERY time, as there was a period a few days ago when it stopped. But then it started happening again. It only happens when I have reverse engaged, if I'm rolling backwards with the clutch in, no squeaking. It's at pretty even intervals too, in relation to how quickly I'm moving. It's coming from the back only, not the front, even in four wheel drive. I can only hear it on the left side, but I suspect it's on the right as well. This started maybe two weeks ago. From my reading, maybe the U joints? Is that a hard/expensive project?
Next is creaking suspension. I'll try to describe where it's at. Imagine where you rest your right heel, to pivot between having your foot straight on the brake, and angled on the accelerator. Right below my heel I can feel what I can only describe as creaking, or hesitation. I think it's the suspension, as it happens usually over bumps or turns, and mostly at low speeds because that's the only time I can feel them over the overall vibration of going down the road. I can only feel it in the front left side, dunno about anywhere else. This has been happening for some time.
I also had some rattling kinda in the middle under the engine. A passenger at the time said he thought it was just the exhaust might have gotten loose, not too worried about that. Also my weather strip has pretty much fallen off, and my bass speaker is shot; but those are not huge issues at the moment.
I thank you all for your time, effort, and knowledge.
