Thumping noise coming from rear of my 06 TRD Offraod 4x4

hey, when i hit a bump with the passenger side rear tire i hear a thump. like something hitting something. i jumped in the bed and heard it too. and also when i hit a bump sometimes my rear end will jump and bounce a little. any ideas?

 

Maybe the shock mounts are loose?

 

how would i go about fixing that

This shows how to replace the shocks. I'm thinking the rubber bushings at the top of the shock are missing. But you should get under there and look for anything out of the ordinary first.

 

Check all bolts in the suspension. Possibly a bad shock, maybe a loose rear wheel bearing. Jack up the rear wheels and give the tires a shake to check for play in the wheel bearings. I had one make a rattling noise on bumps. It also had a roaring sound that got louder with speed. It sounded kind of like mud tires. If you have loud exhaust or aggressive tires you might not notice the roaring noise from a failing bearing.

 

Make sure your spare tire is tight too. I had one wiggle loose on my dodge and it would clunk around.

 

Get underneath your truck while a friend bounces it up and down to replicate the sound. Repeat until you find the source. It could literally be a 100 different things. Not easily diagnosed on an online forum.
