got some today as i intend in changing the wheel bearing at the weekend and the other side driveshaft in a couple of weeks so i thought it would be a good idea to wack the volvo ones in.

my question is are there a straight swap leaving the bush on the volvo one's (i take it the st one doesnt have this as the one with the bearing doesnt)

also how much should i torque them up? there seems some debate when i did a search.

any help would be appreciated

The bolts that go in the centre of your hub/driveshaft. The standard Ford ones do not have a bush on the end whereas the Volvo bolt does. As you will probably know a lot of Ford parts are also common to Volvos also, as Ford own Volvo. That is why Ford use the Volvo engine in the ST amongst other cars. In general the Volvo is a better quality screwed together car, as such it has a damping bush on the driveshaft bolts that Ford chose not to fit possibly to save money maybe? However the bolt is a direct replacement, doesnt cost any dearer than the Ford original part and helps stop the driveshaft knocking/clicking, although Ford now also recommend locting the driveshaft splines also if you ever dismantle the driveshafts from the hub. These bolts should always be replaced after dismantling as they are "stretch bolts", this means they are designed to be torqued up only once. Hope this explains it.

Another couple of questions on the subject of the driveshaft bolts and the torque settings. Firstly regarding the 50Nms that they are torqued up to. For "stretch" bolts this doesn't seem to be very tight. They ain't gonna stretch much at that torque!

Secondly, the cooking version of the Mk2 focus has a tighter torque setting and a further angle tighning sequence, not that would stretch the bolts, surely. I would have thought that with the forces put on the ST compared to the standard car the torques would have been at least the same for the same.

PS. I've torqued mine (Volvo versions) to 50Nms and ledt them at that.

Not really it wasn't making a noise before. As the advice was it's better with the bush on it, I bought it from a local Volvo dealers off Ebay.

I actually replaced it as I replaced the tripod joint boot - O/S of course(a bloody expensive for a boot kit - around ÂŁ50 from the dealer).

It didn't seem that tight when it came off compared to others I've loosened which can be tightened up to over 200lbft.

I was just curious about how much stretch you get at 50nm which I reckon is about balljoint tight - not slack but not that tight either.

When I think about it though quite often the bolt or nut size is a fair indicator of the tightness of the thing and at 13mm maybe that's reasonable. Though as I said, according to Mr Haynes the "cooking version" of the Focus Mk2 is a bit tighter on the initial torque and an angle tighten (can't remember exactly what it is) after that.

When I went to see Gary about a possible driveshaft related issue - I actually took these bolts with me and he said not to bother as they're too long and can cause further issues? I still have them sealed and the chap I got them from off eBay said I could return them.

Thoughts?
