After translating and spell checking you post I know understand lol

Check if the rear brake caliper is stuck on

Also get the car 4 way alignment done at a proper garage, as camber and toe settings always get thrown out of range when replacing the suspension with coilovers

if the wheel is getting hot, then it is either the brake sticking on, or maybe the wheel bearing is going?
 
Jack the rear end up and carefully rock the wheel back and forth  check to see if there is any loose play in the wheel.
 
Check to see if the handbrake is moving freely too

there is a bit of play in the wheel not much can this be making the knocking sound thanks..
Title: Nocking from p/rear
Post by: AtomicRex on September 10, 2009, 04:38:49 PM
yes
 
If the wheel bearing is loose then this will cause the wheel to vibrate.
 
Are your nuts done up?

Title: Nocking from p/rear
Post by: AtomicRex on September 10, 2009, 04:57:45 PM
wheel bearings are approx £50-60
 
Could be you have a duff shock....could also be that the pillow ball joints.

I\'d say it\'s worth checking the pillow ball joints too, mine did this, a bump or hole caused the knocking sound on mine, was the pillow ball, costs about £30 from mazda IIRC but they are a bugger to replace yourself unless you have a press

Post by: AtomicRex on September 10, 2009, 05:57:09 PM
£30?  I doubt it!!  More like £50 odd
 
They are an expensive item...and not one anyone else produces :(

I took the wheel off and it had lots of play on the pillow ball. It could be the rear hatch but that usually squeeks not knocks, my used to squeek so i fillted some plastic washers under the rubber stoppers (there\'s 2, one each side and are a black rubber), this raised the stoppers and stopped the squeek, takes 5 mins to do and would at least rule out that being the case bud.
