Everytime I take off or slow down I hear a clunk and the rear tires kinda shutter. I've changed the u joints and tranny mount. What other things should I check. It's also got an ox locker in the rear with upgraded axle shafts. Let me know what you think.
First thing I'd do is remove the rear tires. Inspect the brakes, rotors, then start pulling on control arms. Try to wiggle the driveshaft and trackbar. If everything seems alright, get those rears on the front, front tires to the back. Still doing it?
That takes care of the easy part. If you still haven't solved it, it's time for a full on axle inspection, most likely a bent shaft or something. I'm pretty sure you'll find what's up when you inspect the brakes or check suspension components. I'm thinking it's a CA or trackbar loose
EDIT: you can also lay under the Jeep and have someone rock it and bounce it around. See if they can reproduce the clunk and follow your ears
I hopped under there and nothing seemed loose except track bar or sway bar or whatever you wanna call. Wasn't really worrying about cause I hear people taking those completely out all the time. But that might be causing the noise.. But would it cause the tires to shudder?
The track bar wasn't the problem.. The bushings were worn out so I took it out anyway. The problem is as soon as you let of the clutch and give power to the driveshaft the rear axle will turn upwards. So um guessing I should invest in some new u bolts since that would be the only thing keeping the axle from shifting up right? The old ones won't tighten without heating up then I would risk the chance of snapping them. Let me know what u think.
