Squeek / rattle / tap, god knows sub frame ?
morning gents
iv got a weird sounding squeek, rattle, tapping god only knows from the back under the rear seats / in the boot area. at first just thought it was loose trim but iv checked everything and no joy, then it deemed on me could this be the sound of some cracks forming in the subframe ?? have you boys who have had this problem ever heard of any thing like this related to the sub frame because its all i can think of now

Assuming when your driving?? Could be broken rear springs, discs, bushes or subframe. Worth checking in that order and getting subframe inspected anyway.

I have a really annoying creek / squeek from my rear seat. Only know it's that as it disappears when i remove them.
For all the time it takes it might be worth a go?

if you pull off real slow does it make noise?and if you pull off harder is it worse?could possibly be prop shaft centre bearing coupling.the rubber piece between the bearing and mounting may have started to split but not ripped completely yet.
