Hi All

[Tyre kicker Gary]

I'm new to the group, have a lovely E220D AMG 40K on the clock and I've joined you guys to try and get some clarity on an issue that I have with it.

I get a constant clunk when it brakes to a stop, then the same clunk when I let the brakes off to move. Sadly, it also does it fairly often just bouncing over potholes or lumps & bumps.

At first I thought it was suspension based, but today, I jacked it up and played turn the wheel and have noticed a good old clunk when I turned the propshaft & held the disc. I can get about 1/3rd of a turn on the propshaft with a clunk at each "stop" I then held the propshaft still and turned the disc, still clunking.

My assumption is... this means worn driveshaft bearings, coz if it was propshaft bearings then it wouldn't clunk when I only span the wheels.

Also, is this it? I don't see how this would clunk going over lumps & bumps, but definitely can see it on stop/starts.

Anybody got any ideas, I don't want to spend £500 on replacing driveshafts if its some suspension bushes.

Help please. - I have a great video of this but its 12mb and so is too large to upload!

thanks in advance for any good ideas

cheers

Gary

Welcome

Find a good Indy and ask them to diagnose. Where abouts are you?

Could possibly be suspension or Ball Joints but the play in your propshaft is certainly suspect. As Dry Run - find a good independent for a proper diagnosis. My thought is prop but diagnose first rather than chucking £ at it and not getting a fix. Certainly it can clunk over bumps as the car negotiates them.

Hi and warm welcome to our forum, I hope you get your issue resolved ok?

Thanks all
I have found what looks like a decent Indy, he's ruled out the propshaft, it's what he says is acceptable backlash.

He reckons suspension bush or ball joint, so it's going in next week for a coat of looking at.

I will report back with what he finds
Cheers.

How did you get on?

Hi All, well, he's a great indie, very thorough. Main issue is front upper wishbone ball joint. 3mm of vertical play. Replacement part is £80.00 which I consider reasonable for the entire wishbone. There's also a small amount of play in the rack to tracking arm joint, so I'm getting that replaced whilst it's in.
FYI indie is Martin - MPH Autos in Buglawton, Congleton.
