Ah, yes, a pattern forming...  ...didn't you used to own a Renault, and say unkind things about it.  Its all payback

[Keith ABS]

  Doesnt everyone say unkind things about Renaults whether they own one or not

Anyhoo - back on topic...

Did you change the bush and has it made any difference to the knock you have..

I have the same problem at the moment...

I changed from air suspension back to MV6 shocks and it has improved but still feels loose, especially when in a right hand corner over a bump, I can feel the rear move then get grip... on left hand corner and a bump no problem..

I shall replace the rear subframe bushes and go from there I reckon...

Im not running Elite suspension, but APEX (-40mm) springs all round with Bilstein shocks front and BORG MV6 rear shocks but will be replaced with Bilstein when funds allow... the rear shocks are perfectly OK and have a good rebound etc... and no leaks...

Not yet, took me around 2 months to get around to changing those shock bushes 

It's clearly from passenger side, spring is fine too, so I guess diff mounts or donut bushes.

However I thought rear donut bushes, stiffen'd things up handling/body roll wise but not known for causing drop-link type noise

Subframe bushes clonk when knackered...

Rear drop links, such as they are, make cockroaches look fragile

Looks promising they are the cause then. Been reading threads on changing them, bit confuddled though, you can put a stand on the subframe like this?



With jack out of the way, releasing the subframe bush cover bolts, can the the bush be extracted with axle stand in position? Or does it need to be moved? To allow the arm to lower?

As the guide says just put stands in normal manner 

[05omegav6]

Back the car onto ramps/curb
Support subframe with a high reach jack
Tqke weight off bush
Undo all four bolts
Remove bush using preferred method
Slap new bushes in
Refit plate/bolts
Job jobbed

You DON'T want the subframe to move

Thanks Chaps. Ramps it is. 

My Big jack should reach sub frame, in some position as that stand I think. Guessing not too much pressure....

Now just to find some time to do it.

Finally got around to ordering these, when I went to order last week only 1 in stock. So 2 are on there way. 

Few questions:

1) What is the preferred method of removing old bush? Perhaps at this age, they might just fall out? 

2) Do the new bushes have to be inserted in any particular way?

3) Worth greasing up and putting them in, or just as is?

4) The plate that supports the bush and surrounding area is rusty, worth slapping on some Hammerite Underbody Seal?

Might take a few pictures and make a guide. 

[Diamond Black Geezer]

Only feedback I've got personal experience of re: the above is don't use Hammerite/Waxoyl seal. It's not the best. Ok if you've got a brand new car (though it's known for flaking off) as you're onto fresh, rust-free metal. Apply it to an older car as 'protection' and you'll be trapping rust (and possibly moisture) under the surface. You'll be looking at a nice black, textured surface, unaware there's a sheet of rotten metal underneath.

Many other products have appeared since then. Rustbuster 121 Epoxy mastic for one


I've yet to replace my rear bushes, and will be doing so with a whole spare subframe I'll be acquiring, with a full stripdown and repaint, new bushes, handbrake etc.. 

[tunnie]

Thanks 

I've still got some knocking at the back on rough roads, drive though a car park at slow speed with big pot holes its fine. But at speed on rough roads, there is knocking from passenger rear. 

New shocks, as old ones where leaking anyway. Checked springs, all good. Rear bushes are original, so thought could do with a change.

Snap  Although after a while say on a long run it disappears

Foreskin ear warmers. The middle may drop out...
