Having some trouble with my Jeep. Squeek in reverse, creaking suspension

Hello everybody,

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.

Welcome to the forum. For the squeak when backing up, I would first suspect a dry/bad u-joint. Sometimes when they first start to fail, they will only squeak in one direction.

For the noise or "feeling" under your feet, might need to check the transmission mount, or at least a good place to start. Also would visually inspect the suspension components and make sure nothing is loose. Good luck with it.

Thanks for the reply.

U joints is what I suspected. They're off and on, not always squeeking.

The transmission, might be worse than I thought. I drove about 80 miles each way today to go shooting. On the way there, no problem. On the way back, no problem until the last 20 miles, where the freeway ends and the city/suburb begins. As soon as I slowed down, I felt the vibration in my clutch, accelerator, and all the way up the stick. It's not that noticeable until I reach 40mph and 5th gear, but at 45 and 6th it's very obvious. It doesn't rattle, only vibrates, all the way up. And it feels rough inside the transmission. Not like scraping or grinding, but just like it's working too hard in there, like it's fighting against more resistance than it should be. It's due for an oil change, but not overdue. I just rolled over 100K miles, and 5 miles later, the vibrations start. Not a good day.

I talked to the family, and got some different answers for all.

My father thinks to look at the differentials for the vibrations. My uncle is thinking that since the rear brakes are drum (only the front are disk, right?) brakes, they might be dirty, and have a tendency to squeak but only in reverse. Makes sense since I go on a pretty long, bumpy dirt road to go shooting. As for the new vibration problem, he recommended looking at the transmission fluid level. Easy fix. Hopefully.
