Hi Mark,
I think we've all spent ages working thru the kilos of rubber bushing under a merc, trying to find the place that one last annoying thunk thump thunk really comes from.
I was just about to swap out the guide rod mounts when I noticed that it was the intermediate arm bush (you know, rubber at both ends, sits inside a steel tube on the other side of the car from the steering box..) that was the culprit.
What I learned is that you need 2 people (one to move, the other to watch) when looking at this stuff. I'd tried alone many times with no joy; did it with a freind and we quickly found the real problem. Hope u do 2
Giles

Sticky brake pad stuff didnt work..but noise goes away when I apply brakes. I will start a new thread on this.

BTW, Tarnbarn, what is the intermediate rod you describe...I dont think I have this on the 123?

Thanks,

Mark

Hi Mark,
It's the bit marked 8 in the picture... comes free with a 123.
I'm crap at describing things with words.
Good luck with your clunk

That part usually causes squeaking when turning the wheel. I had already replaced that...plus my "clunk" is further forward at wheels.

Thanks,

Mark
