Hey guys anyone know about this, when I am going over large bumps and the rear come down it makes a loud almost metal sounding clunk and I've had shocks and springs replaced, is my problem old bearings? Because they have never been replaced and if so what ones would I get for a comfy ride at 80mph but good on the off-roads?

 

Check your bushings
check your drive shaft

 

Have you tried to replicate it when parked by bouncing up and down on the bumper? One person doing the bouncing and one underneath works well to locate the culprit(s).

 

maybe but Well it's more of a very large clunk where it would probably take a bit more than somebody jumping on the bumper, although I could try. Only when let's say on an off-road trail and I hit a couple holes and it just bounces very hard in the back when it come down.

 

I had the same issue a few years back. It was the Watts linkage. The bushings were shot. I did the work myself (local garage pressed the bushings in). Not a bad job once I got the loosened up.

 

Get under and look. It could be as simple as worn out anti sway bar links or loose shock. Use a pry bar to move stuff around if it's not obvious.

 

We diagnosed this issue on a D1 this year on the trail. Owner had recently swapped in the shocks, too. I guess they didn't get installed correctly. But, we found it by bouncing that back end up and down. Easy to see when following the sound.

You can get one of these moving pretty good by bouncing on it.

 

After installing my lift I noticed the same clunk.... my rear shock wasn’t tightened enough. Problem solved... a month later I have a new clunk and it’s not the shocks 🙄

 

Check Watts link bushings.

 

I had a very loud bang, when driving , jacked it checked every bush I could find with a pry bar, all solid, took it to my local garage , on the ramps nothing found, only thing they could say was maybe a worn shock absorber, so came home jacked it up removed the shock, but to put it back I had to drop the axle down, as I could no compress the shock and fit it, that's when I found the problem

the Ball end socket on the drop link came apart, as the axle moved it just went back in as it was so stiff it did not move so a constant bang and as the vehicle is so heavy no amount of shaking on the ramp moved it enough to see
