Reading through this thread filled me with certain degrees of dread.
I'm interested as to why you are worried. Do you have a fear of the parts failing or my workmanship
Do you really need to resort to Mercedes parts to get the job done? And are the unverifiable Alfa Workshop parts worth the risk, until proven otherwise?
Why not, its appears to be an equivalent part, the 166 boys have been using it for a while and I've seen no reports of it being a bad part. Dare I say, it may even be better specced than the original. As to unverifiable Alfa Workshop parts, I don't think a recognised specialist would risk their reputation and sell poor parts?
I agree with batwad. Get the job done by a professional outlet such as Autolusso (which I suspect is where batwad got his done, being in Beds). Powdercoating the arms is also such a good idea, especially the springpan arms, which do corrode and can fail the MOT in their own right (and that's before you get to the bushes).
The arms will be stripped and hammerited.
Save yourself the hassle, the struggle to get the old bushes out etc, get it done properly. And yes if the upper wishbone balljoints are newish, don't bother with the upper wishbone bushes, they hardly do anything anyway.
It's no hassle, I have access to a press at work, and I don't see why the job wont be done properly! I enjoy working on the car, it gives me something to do when I'm bored
EDIT: May have come across a bit defensive there, changed the wording a little!
