LMM: Rattling from rear wheels

[MDJ]

So, when I'm rolling down the road, bumps seem to be causing a rattling noise. It goes away under braking.

Curious if anyone has experienced this or knows of common parts that may come loose in the braking system?

Calipers can make some noise on the slides sometimes. Happened to me a while ago I just pulled the caliper off and lubed up the slide pins really good and it went away. Good plan e to start but it could be anything.

Insulator pads are probably missing from your rear springs.

That makes sense. I couldn't find anything loose under there.

I got the dealership to redo all the brakes and a high pressure p/s line that was seeping. I guess we'll see how she fairs after Thursday!

Thanks for the prompt response. I'll post back with any findings.

I have a rattle in the calliper right now.
If the rattle goes away when you have pressure on the brakes then that is your problem.




Get it on
Got to get it on!
No choice but to get on!!
Mandate... Get-it-on!!!

I figured as much. Thanks for the input, fellas.

Have you considered a bad universal joint? I recently experienced similar noises that disappeared when braking. Pulled the wheels to inspect brakes

Have you considered a bad universal joint? I recently experienced similar noises that disappeared when braking. Pulled the wheels to inspect rear brakes, nothing wrong. Jacked up and ran while rear wheels off ground, no noise. While having the transfer case replaced (local garage) for pump rub-through, my guy discovered a bad rear universal. Noise gone.

I hadn't considered that...

However, I did a brake job and the noise definitely subsided. I still hear it faintly from time to time.

I'll have a look.

Thank you!
