Rear squeek - so annoying - please help!

[LMStaples]

Hey,

 

I've had my new 370 for a few weeks now and there is an annoying squeek coming from the rear (I think).

It seems to be more prominent when going over bumping terrain (UK roads 😒).

I'm replacing my brakes soon so I'll have a chance at looking at the suspension and under the car whilst it is up on jacks. 

Are there any known issues or anything specific I should look out for to try and diagnose and fix the noise?

My current guesses are something suspension or bushing related with the rear diff / sub-frame.

Thanks

Is it squeaking or more like a clicking / thunk sound?

Nah it isn't a click or thunk; its a squeek I can only decribe as a muffled dogs toy.

Up and down as u go over bumps? sound like its coming from the rear shock tower?

[LMStaples]

It's less over harsh bumps, it's more noticeable over uneven ground. To me it seems to happen more when the rear rotates about the main axis

Loose interior trim or rear hatch maybe?

 

If you think its suspension spray WD40 on shocks and rubbers and see if it stops, think you'll have to follow a process of elimination

Yeah I am changing the brakes at the moment so will fiddle with the suspension and see if I can clean it up and re-bed it
