I have a rumbling sound coming from what sounds like the passenger front end at 15 mph and again but quieter at 25 mph. It gets much worse if I am turning left. Could be some sort of vibration.

Replaced CV's, ball joints, and wheel bearings in the last month. Ideas?

oldblue

was it there before you replaced those parts? i'd jack up the front end and shake it down to make sure wheel bearings are still tight. do you have auto locking hubs or manual?

wberry85

Yes it has been doing it since I bought it.

Manual hubs.

turning left puts the weight of the vehicle on the passenger side. sounds like a wheel bearing issue kind of. when you replaced the wheel bearings did you install new races? were the old wheel bearings pitted?

wberry85

The wheel bearings I removed looked fine. Spun them over and no noise. I did not install new races. Looked inside and didnt see anything terrible. I didnt have any races at the time and the current ones looked ok.

What tires are you running?

The clutch gear in the hub might not be attached to the spring which turns to lock and unlock it and could be stuck in lock

Bald procomp mud terrain

I can rotate between free and lock no problem.

Tires sound like problem to me. My km2s roar in a turn

wberry85

Maybe I could try rotating and see if it changes

Check spindle bearing and bushings that sounds like the same problem i had they dry out and then loosen up and allow the cv shaft to move around through it. As a tempoary fix use a grease needle take apart your hub and inject it till it comes out around the sides once you do that you shouldnt be able to move the cv shaft up or down.

^^^This, before putting money into anything else. I've had mud tires make all sorts of terrifying noises especially when they get worn pretty low.

Yep I had the same problem when I first got the car. New tires fixed me right up

Guessing tires +1

wberry85

Tires were the issue. You dont even want to see the way the front two were worn.

Some new claws fixed me right up!



Only issue is the shop says steering components were too worn to do a proper alignment so I guess these will suffer the same fate.

Good thing I am picking up a solid axle tomorrow!
