To cut a long story short, I got a set of Koni FSD Dampers and Eibach Springs put onto my 147 (did the front myself, got a indy to do the rears) about 9 months ago. I had the car in for a service at the dealers last week and asked them to take a look at the suspension to figure out which bit is making a knocking noise. When I went back to them I was told that the whole rear left was moving about 2-3mm up/down which was causing the knocking, but they wouldn't fix it cos someone else did the work originally.
Fair enoug says I. I wouldn't want to sort out someone else mess either so I brought it to a garage down the road from me to sort out. Went to them yesterday to pick it up and the guy there says that its perfectly normal for the whole suspension unit to move up/down a few mm and that most new cars are designed that way. The rear right which wasn't moving up/down had the spring mounted wrong and when he remounted that, the whole unit was now moving up/down a few mm just like the left.
What I'm asking then is who is telling me porkies. Is the dealer right in saying that the suspension unit (damper, spring, wheel hub) shouldn't have any play in it, or is the indy guy (not the one that installed the dampers for me originally) correct in saying the there should be some play in it.
Incidently, the indy identified the knocking noise as a knackered front left drop link, (dealer missed this) thats already the fourth one put on in 4 years. I think Alfa should make them a servicable item at this stage
Sorry for the long post but couldn't really make it any shorter.
