2004 V70 wheel bolt torque

[Phil Russell]

I have come across various references on these fora to wheel bolt torque being 110Nm (81 lbft) but my recently purchased Haynes manual says 140 Nm, 103lbft. Which is right?
I run the 17" alloys.
Cheers, Phil

The earlier cars are 110, the newer ones 140.

Either will be fine, obviously 110 is easier to get off at the side of the road but only marginally so.

Thanks VolvoT5 ... since posting I actually looked in the 'handbook' with the car and it says 140Nm ... moral always read the manual although I did not expect to find it given there.
Out of interest I have never torqued any bolts or wheel nuts before on any of my cars. I checked how tight I would normally do a wheel nut or bolt using my socket set and it came out at about 82ftlb .. so quite a good guess. My torque wrench... previously used for wheel bearings and the like on my older cars... is longer than my socket bar so will be easy to get to around 100 ftlbs.
Am I the only one more used to ftlbs than Nm?
Thanks again
Cheers, Phil

Hello Phil. No, you are not the only one using Lbs.-ft.
I started driving and working on cars in 1959 (I'm now 75! ) so I don't have a clue what people are on about with all this Nm rubbish. !!!!
We Cambridge-its. must stick together.

Yes your wheel torque is 140 nm

All the cars except the C70 (which is really an 850 ) with the 14mm thread wheel bolts from 2000 to the current day use 14mm threaded bolts and all are 140 nm despite the bolt type changing from a friction cone to a fixed cone in 2005 ..

110nm is for the 850 and C70 and First generation V70 from 1992 to 2000 .

110nm is also for the S40/V50/C30/C70/New V40 range from 2005 to 2008 when a new nut with a washer was introduced and the torque went up to 130 nm .

You would think they would put a torque wrench in the tool kit .
however it's common sense , with the tools provided when you tighten until the bolt goes no further its around the correct torque . the bolt tightens and suddenly will not go anymore as it is a tough bolt and not elastic . Unlike some Renaults which just go on and on with medium hand pressure until they shear off . Never let anyone use an air power tool on the nuts , it cracks the chrome plating and they will then rust .
