One of the million other problems my cherokee has is when I take off I hear a clunk when I come to a stop I hear a clunk again. It has been suggested that it is my drive line. My "boyfriend" is adamant that it is absolutley NOT the driveshaft and it could not even possibly be.

Any suggestions as to what it could be. I am pretty sure it's not something sliding around my cargo area.

Clunk

Hmmmmmmmmmmmmmm! That "boyfriend" thing again. Could be suspension bushings or u-joint or anumber of things.

DRIVESHAFT

I just went through this same issue. When i stop..."clunk"...when i go..."clunk". I can't hear it but feel it. It's the slip yoke needing grease. Doesn't sound like a culprit but it is. Unbolt the rear driveshaft and shove a handful of grease in there and on the splines. See what that does.

This problem is so common. You'll see it pop up on any cherokee forum pretty often.

if this is not the issue, it's probably a bad bushing somewhere, or possibly bad driveshaft u-joint. Have your BF walk along the side of the jeep while you stop and go. See if he can hear the clunk and pinpoint where it's coming from.

Beware clunks when changing speeds! Could also be a sign of a pinion bearing on it's way out. What area of your Jeep is it coming from?

Does your truck bump from side to side when you brake hard? Does it wander excessively? Any other bad vibrations or rumbling sounds? Any rattling when you go over train tracks etc? I ask these because sloppy control arms, bad shock bushings, sloppy tracbar or sway bar can all cause this.

There are several other clunk inducing issues that may be present. U-joints, sloppy yokes, bad pinion bearing, even worn out splines on your axles can cause clunks.

Worn out brake hardware - particularly in rear drums can clunk too. A sloppy tranny or t-case can also clunk.

Need more information.

Sounds like the clunk is coming from my rear end. Err umm the jeeps rear end I shoujld say. My boyfriend can not hear the clunking but I can. I can feel it as well. It does always do it but it does do it. Started right after we but the whopping 2 inches of lift on it.

You need to lube the slip joint where the rear driveshaft meets the transfercase.

u-joints and the trackbar are usually a good place to start if its coming from the front end. or do like i did tonight and run it through enough mud to take care of the sound for a temporary fix :thumbsup:

If I turn my stereo up enough I can't hear it.

:rofl: Thats the way I deal with a lot of my clunks. But yours is a pretty easy fix.

It is lubed by the tcase.

It is lubed by the tcase.

You thinking the same thing? Mine is not lubed by the t-case. It takes grease. Without grease, it clunks.

Good call, I keep forgetting she has an older jeep. I need to pay more attention, I think its pre 97 that the transfercases were lubed internally.

Something like that.


My thought is old u-joints. But I wouldn't say for sure.

X2 - I'm thinking rear u-joint or possibly a worn pinion bearing. Changing the drive line angle may have unmasked the issue. The pinion bearing could transfer that slop to the pinion and the ring gear and cause a clunk.

I would say change the u-joint first and if that doesn't fix it you may need to shim your rear axle to correct the pinion angle. Odd that it would surface at 2".

I have chewed through a few pinions and in my experience they slowly get worse. If it's a D35 and it is the pinion bearing it may be cheaper to replace the whole rear end.

Keep an ear on it.

To the OP, see if there is play in the rear driveshaft.

I paid more attention the last time I drove it. It only clunks when I hit my breaks. I asked my now ex boyfriend (who has given me such excellent advice in the past- NOT!) why my breaks are clunking and all he said was "Uh they shouldn't be clunking" Happens if it's wet out or dry.
