Rear Suspension "CLUNK"???

Superpro poly I'd use any day.
But otherwise only OEM rubber.

Poly, done right and correct durometer will be great.

SP use multiple material specs and designs to keep flex and ride.

My money is on the Watts linkage in the three centre bearings on the rocker. If you go ahead to replace these, insist on genuine only parts here or minimum A-grade parts. Last thing you want is to be replacing these just weeks after doing them. Don't ask how i know :wasntme:

Hmmmm.... Lots of food for thought. Daisy has her MOT on Tuesday, I'll get my tame mechanic to have a look at the rear end bushes on his ramp.

The springs aren't seating properly, (beginners mistake....), so facing the fact that I'm running out of time to prepare for the big trip I called the services of my trustworthy mechanic. This is happening tomorrow the 10th April.

Regarding the CLUNK noise some of us are experiencing:

I also mentioned to him a clunk that was there before and still exists after the new suspension being ....."installed". It feels like it's right under your foot, and sometimes also at the rear. I notice it more in wet weather, coming out of the driveway, sometimes driving along when there is a bit of suspension movement or coming to a halt and taking off.

The diagnoses from the mechanic is that it's the bushes from radius arms and trailing arms. This is apparently a common problem with a simple solution,....replace with new.
Well, the bushes from the old shocks looked like pancakes already, so I'm not surprised that other rubber is reaching the end of their life span.

My immediately question was......have you got Poly bushes ?
His opinion is that I better off put original rubber bushes, his opinion is that poly bushes aren't very good for this type of vehicle.
I'll find out the reasons behind this tomorrow and let you guys know.

As I thought the the springs weren't properly in place and the the other clunk noise was the radius and trailing arms bushes. Everything is now running fine, in fact, the ride is very good, particularly when loaded.


As for the mechanic's negative comment regarding poly bushes, the reason is that they restrict the travel greatly and they tend to brittle over time and fail without warning (not good if you're in the meddle of nowhere.

OK, I got to the bottom of this . My bilstein shock adsorbers were actually too short, and they were fully extending and "clunking".

New proper length bilsteins, no more problem.
