Parking Brake Clunk?

Over the past 1-2 years I've been chasing a clunk/rattle in the back half of the Jeep. It mostly happens when driving down rough gravel roads or paved roads with a bunch of uneven patches. It doesn't appear to be causing any issues except for annoyance. I have found that if I pull the parking brake up 2 click it stops the noise from happening.

A little bit ago when I finally got annoyed enough with it, I checked the rear A-arm bushings and ball joint. The bushings were shot so I replaced them and the ball joint. It still clunks/rattles over rough roads.

It's odd to me that the noise goes away when I tighten the parking brake a couple clicks. Could the cable have slack and be causing something to hit? Is there a way to adjust the cable to take up slack?

Normally I would go check sway bar links, shocks, and control arm bushings. But those should clunk all the time. Any ideas?

Re: Parking Brake Clunk?

I have the same annoying clunk and have replaced all three control arms and ball joint and it persists. I thought I finally found the issue when I discovered that one brake cable bracket bolt was never tightened and the bushings that come out of the body were sloppy. Tightened the bolt and zip tied the cables together slightly to put some pressure against the bushings. Neither helped as it turns out, but may help you.

My Jeep does the same thing. The problem is the side gear in the rear-end. Jack up rear wheel and rock the wheel up and down. The rear axle will move inside the the diff.
I found this out over the last weekend when I took off the cover to do a fluid change. I believe a new set of spider gears will help this.

Funny you mention that. Yesterday I was trying to diagnose bump steer by shaking the top of the front tire pretty violently, and could hear my noise in the back. Sure enough, shook the rear tire and I believe my bearings in the rear are bad also, and the seals are leaking anyway. Midas gave me an estimate of 450.00. Uhg. Maybe ill attempt myself. Question. Rather than using a grinder to split the bearing, can I use a bearing splitter from Autozone "rent-a-tool'? Never used one before.
