Anyone encountered this on a 166?

It was knocking when I got it on harsh bumps from LH side. I replaced the strut, coil, Strut top mounting bush, Upper Wishbone, Roll bar drop links, and lower wishbone.

Still knocked afterwards. Took it to a reputable aftermarket suspension specialist. had it for a day and said the knocking was coming from the LH tower. They replaced the Strut top mount again, and in the process dismantled that whole strut and put it back together again.

Whatever they did, improved it considerable, but it still knocks on speed bumps and pot holes, so they didn't charge me for it. They said I should take it back if it gets worse, and it is back to it's old ways... almost.

SO what do you guys think it could be? Any known issues? I didn't replace the Roll bar bushes, but they looked ok.

You have changed everything which would normally stop knocking, but I had the same and it was the anti roll bar bush. When fitted it did not look to bad but when removed this was how they looked.

Both were changed at the same time.

..just in case by "left side" you mean "right side", it might be worth have a close look at both ends of the top engine mount.. when they clunk it sounds like a suspension clunk, but luckily it's a very handy clunk to fix...

thx for the suggestions. drops links replaced.

The only reason I didn't replace the Roll bar bushes was because the seller on ebay let me down, and I didn't want to wait any longer. I'll get them replaced and see if that cures it. They don't look as bad as those in that picture though, but if that's what caused the knocking on Paul.O's then it's worth a shot. I suppose I can't tell how bad they are until I take them out. Pretty easy job I think too.

err no, PITA job, at least on a 147 but the set up is the same, just a bit more room to work on a 166, the only saving grace if changing the damn things did actually work. The subframe has to be disconnected at the rear to allow some downward movement so the ARB can be pulled out, this involves removing exhaust, disconnecting steering, undoing the strut from the wishbone etc etc. Nightmare.

Normally in my experience.

Knocking = Drop link or anti roll bar (replace the links first)
Squeaking = Upper Wishbone

Done the Drop links, time to do the anti roll bar bushes.

Where can I buy these, what aftermarket items/alternatives are there?

the sole seller on ebay pretends to sell them, but if you try to buy them he tells you he can't source them anymore.

Alfa Dealer tries to sell me the entire ARB, which will be a pain to replace compared to just flipping out the bushes.

So The 'pretend' ebay seller advertises the 166 bushes as a 21mm bush. Is this correct?

Anyone suggest any 21mm alternatives? They look like a pretty standard shape to be honest, so there is sure to be sone suitable alternatives.

EDIT: I just measured it with a vernier it's 22mm. So much for ebay.

Thanks, I've got some Generic Poly Bushes, 22mm, and the certainly 'look' the same shape, they were only 10 pound so I'll give them a go at the weekend, I won't put too much faith in it though.
