Default Top mount assembly, and renewal

Hi all

Just been trouble shooting a problem with my front suspension topmount. A clanging/twanging of the spring when turning at slow speeds.

I clamped the spring down to relieve pressure on the top mount and the rubber seat and metal ring dropped down with the spring.

I can put my finger on top of the metal spring and feel ball bearings floating about loose and free. Assume this isn't right!

Which bit needs replacing? Anyone got a good exploded diagram of it all?

Cheers

I've never heard of the bearing breaking up but it sounds like yours has. I don't have a diagram handy but basically, the spring loads the upper mount bearing (via the rubber bump stop) and, if it is failing, will cause the effect you're getting. You need to extract the leg from under the wing and replace the bearing. This can be done on the car. You need good spring compressors and may want to change the shock(s) at the same time. Not too bad to do. Regards.

Yes it has broken up, see pic! I'm looking for the correct part to replace and struggling though - is it just the bearing I need which is pressed in to the top and bottom metal parts?

Karlos, the eBay/PartsForVolvos topmounts do not include the bearings so they're no good. If you remove the topmount, you can take out the bearing which seems to be pressed in to the bottom metal plate (right of pic). I've ordered two new SKF bearings from EuroCarParts, part no. 669880020 @ £15 each to replace it.
