Leave the Volvo bush on, torque up to 50nm.

 

thanks matey

 

Np Daz. I have them in both my driveshafts. Lot better than the Ford offerings !

 

well i thought it would be daft not to put them in while i was there

 

What are these guys?

 

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.

 

Does anyone know the part number for these or do Volvo only do the one driveshaft bolt?

Cheers

 

The part number on my volvo one is 30714142, and it would see i need another one..

i'm so pants with these things..

Popped into my local Volvo dealer today to get some drivshaft bolts ready for a service next week. Quoted the part number to the parts salesman and he said they are the driveshaft bolt for the XC90!!! I was expecting them to be for a C30.

Can someone confirm these are the right ones before I go pick the up?

Cheers.

 

Yes they are correct, it does shock a few people when they say there off the xc90

 

The price shocked me more. £3 for the C30 ones, £18 for the XC90. I knew something wasn't right when he quoted the C30 ones.

Cheers though.

What time di you get away on Sunday? We didn't leave til about 7. Traffic was worse on the way out!!!

 

I waited till most of the traffic had gone from inside, i left about 7:30 and took a very steady drive home as i cooked my clucth on the way in

 

part number 30714142 Torque to 50Nm.

 

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.

 

Have you noticed much difference since fitting the Volvo part?

 

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 £50 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.

 

Surely you are stretching the rubber and not the bolt?

 

You compress the rubber bush with the washer on the bolt and as you tighten the bolt it stretches. The rubber bush helps to dampen out click from the driveshaft splines moving. Another way of achieving this is to threadlock the splines on assembly (as ford do in the recall)

 

Hi guys,

I'm looking into getting my Driveshaft(s) replaced/refurbed very soon, would you recommend I have these bolts fitted when I do?

 

Most definately

 

on another note i didnt have driveshaft click untill i fitted a new bearing and volvo bolt

 

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?
