Knocking sound, rear end AU XR

I put some new tyres on the AU XR8 about 2 months back, ever since then, i have had this knocking/rattling sound when you go over a pot hole, coming from the rear passenger side, and it sounded like shocks to me. I had 2 opinions from suspension mobs in town, and they said it sounded like shocks too. So i pulled out the shocks, and they were nackered. So i put some bilsteins in, the ride is HEAPS better, but that knocking sound is still coming from the back left end, any ideas guys ?????

Re: Knocking sound, rear end AU XR

XR8fella, I had the same at only 11,000k's and its happening again at 40,000k's.
Its your top bearing plate which mounts to your chassis and the strut. The rubber insulator lets go/splits and causes knocks.
I'm surprised who ever put your Bilstein's in did not inspect/ notice this as they have to take these off to replace the struts.
Mmmmm labour again

Cheers
Maurice

Happy to be of help, should have mentioned this on my previous post, my Ford connections have told me this has happened to quite a few. Mine have been replaced under Warranty take yours back to the dlr to get replaced.

I have just had the rear suspension bushes changed in my XR6 at my local Ford Dealer.

It took 2 goes for them to get it right.

The first diagnosis was that it was a "D" bolt hanging off the towbar. After pissing myself laughing in the guys face and calling him and his technician mate complete morons, I took the car 3 km's up the road, turned around and took it straight back.

Unfortunately, the first 2 imbeciles had left for the day. So I asked for another technician to go for a ride in the passanger seat. I went over the first speed hump in the car yard and he picked the problem staright away.

Moral to the story - you can't put brains in statues.

It sounds like a rattliing shock absorber. Its not real loud, but its loud enough to get on you nerves straight away.
