Right looking through articles..... got a feeling ive got a broken rear spring again..... however if I don't find a broken spring or leaking damper I think im looking for...

1.) donut bush in between chassis and that triangular plate (is this the trailing arm?). Should I try and lever this plate and if any play then bush is fubar'd?
2.) testing top mount.. get in rear and put hand on it whilst driving (someone else driving obviously  ::)) what am I looking for.... noise, play?  :-\
3.) lastly loose exhaust mounts. I know how to check these :)

1 no levers, just a prod. Looking under the car by the triangular plate, on the opposite side you can see a gap between the plate and the body of the car. Using that as a guide you can put your hand under the side nearest you and feel for the rubber of the bush behind that triangular plate.
You'll feel some rubber lumps, these are little bump stops. Push these side ways. If they come loose, replace. They,ve gone rusty and seperated the rubber from the metal inner.

2 correct. You'll get some vertical play as the rubber takes up the slack, that's normal.

3 oh, ok good :y ;D

awesome thanks chris. if it turns out that these donuts are fubard as per this testing.... do these cause a creak? I know for a fact that rear broken springs do cos that's exactly what I had when I brought it to you...it then went away  :y

They can do, but not always.

I like the terms used in Entwood's screenshot..... "Deforming....... with suitable tool"  :D

IE: Beat the shit out of it with a rather big hammer!!!  ;D

I get a cracking/creaking noise sometimes from that area so I'll have to try a bit of deforming!!  ;)

Not entirely sure how that solves anything :-\ creaking implies flexing, denting summat that already flexes surely weakens it further, unless I've missed summat :-\

Just out of interest I checked all the rear with it up in the air including donut bushes... is that ok? i.e. it doesn't have to be on the ground to test like the WB balljoints?

no way mate... im not removing anything  ;D just testing for now. ill post up my findings in a bit.

to be honest it sounds like a lot of people get the creaks. not sure I'm going to worry about it TBH. but its nice to know what I need to replace should I want to make it perfect :)
