I think I'm going to have to revise my original opinion and agree with Dr Gollum. A couple of hours fannying about under the car this afternoon and I came to the conclusion that for the top hat to have equal clearance all round to the turret top in the inner wing you want the large hole inboard, and the small hole outboard. That's 2 hours of my life I'll never get back!

Two hours ? And the rest. Anyway, did you like my tin foil and cardboard FA Cup replica? And my real Top Hat?

The discussion is about the coil spring upper seat, item 2 in this drawing.
My apologies for the broken link to the drawing that I posted earler. Here is the corrected link that works.

This happened me last year. Something started to make noise in front after changing shock absorbers. My findings was that the outside of the #2 on the picture was hitting the arch. This may be also caused by the problem I have now (huge cap between arch and top plate) but anyhow I didn't turn the #2 I only took hammer and hammered it down 2mm and that did the trick. Next time I'll know to turn it to right position  :y

It's possible I suppose, but I think your problem is with the top mount. Here are a couple of pictures of a virgin setup :



You can see that the 6 rubber ribs on the top of the mount don't protrude above the top of the outer part of the bush. On your photo in the other thread you can see the rubber ribs, and the middle part of the bush is even higher. Something very wrong there IMHO and I'd be taking it apart before driving anywhere. Also, what does the other side look like? The same?

Old and worn top mounts can easily compress 15-20mm which would result in the 6 ribbed bits poking through even if nothing else is goosed.

My old MV6 was a bit like that, though not as bad, when I took the old top mounts off I put them side by side for a comparison.

I'm struggling to imagine how the rubber can deform 15-20mm without something else being wrong there too. There is a metal washer (17 in the image) between the strut and the underside of the top mount, so that would have to either be punched through or badly deformed.  And how much clearance is there between the strut top and the underside of the bonnet? One good speed bump and you might find some new piercings in the bonnet. :P

Something is pushing up from below, something of a smaller diameter to the rubber mount. I知 trying to work out from the exploded diagram what configuration would cause it to look like that.....but I知 struggling.

The shoulder on the top of the strut is about 2mm wider than the threaded part that goes up through the top mount :



This shoulder sits on the lower strut washer inside the top mount



You can see the silvery ring where the top of the strut has been pressed against the washer. On the LC, the washer punches through there. I believe Ian M (of ABS fame) also said he'd seen a few Carlton GSi's do the same thing. Once punched through all the strut load is transferred to the metal tube up the middle of the top mount, rather than being progressively distributed into the rubber by the washer. To me, that looks like what's happened here (assuming the washer was actually fitted in the first5 place)

There are some pictures of what happens to the washer on Dave F's site here :

Yes...I see. If that痴 the case in Muromans car, one large pothole should do the trick.
