Should you be able to turn the top mount by hand?

[Jon.G]

Since having my car back from birchdown, I've noticed there is a knock on the passenger side going over some bumps in the road. Had a quick look at my suspension at weekend and you can turn the top mount with the piston by had. Now then, it has the new style top mount kit on it, so sits away from the chassis slightly, and the dampers were refurbished by BG in august. Since then I've covered approx 5k miles.

My question is, if anybody else has the new style top mounts if they can spin it with there hand and the piston moves too?

I can't test the other side, as it has the old style topmount which sits flush on the chassis.

I was thinking it might be the balljoint the knocking, but after seeing it move I suspect something else has gone? Any help advice?

Anybody any ideas?

i dont have trophy but i can spin my old style top mount hats by hand and remove them by hand admittedly its tough but can be done

Does the piston from the damper turn with them?

I've ordered a ball joint anyway, as that could be all it is.

I've had issues with the new style top mounts. The new designe is flawed still IMO. Had to revert to using the older style stuff on one car to stop it knocking. f**king renault

Is it the usual full lock knock that you've still seen danny? As I don't have that, its just over bumps in the road which is why I've ordered a ball joint.

no it shouldn't turn IMO, never had a problem with the new ones

He's not paid up

Ah right. Guess I'll have to have a look this weekend and find what the cause of this is. Sounds like the whole suspension unit is moving going over bumps (not compressing, but being pulled back)

no it was over bumps as you said. one side was ok, but the other wouldn't do what it was told.

I might stick the old top mount back on then. As I never really needed to change it to the new style anyway. Funny how it only knocks on the side with the new style top mount...

i had to battle to get my top mount off to fit my washers, but after that i only tightened them slightly so id imagine if i really tried id be able to get them off by hand.

original top mounts though

Sorted my problem. My Sach damper is fucked again after 4k miles/6months.

Me and Ben at BG Motorsport have concluded that the wrong piston was changed during the service carried out in august. On a brighter note, if this turns out to be true (which we are sure it is) he'll be refurbishing them and replacing the piston FOC.
