V70 hub bolts

....and if you do fit XC90 bolts, they do not work loose so never need 'retorqing'.

are the ones I linked to the correct ones? Will get today if they are.

The way most dealers are today they will be special order,or they only have one in stock.

Just make sure you push the shaft into the box EVERY time you move something. The shaft has a habit of sneaking out when you're not looking

Tell me about it, that's why I had a new driveshaft fitted when I managed to break mine trying to change my wishbones. Personally, I'd let a garage do it then it's their fault if they knacker it up.

They don't look anything like them in the schematic mate. The XC90 bolts have a large conical rubber washer on them. I would get them from the dealer if i were you. They also come with thread lock already on the bolts. Just remember that these ones must be torqued to 50NM not 35NM that the other ones do.

Top tip

Spray a tiny amount of WD40 (or similar) on the face of the rubber washer that will go against the face of the car. This prevents it sticking and ensures the correct torque when tightening it up. Don't worry about the lubrication affecting the bolt. It's the pressure in the rubber washer when squashed up that puts tension on the bolt and prevents it from coming loose. Mine have been on 18 months now and they are fine.

I replaced mine recently after replacement wishbones:

Got them from the dealer today. Special order. £19 each!!!!!!! Hey ho, what price peace of mind?
the old ones should come out fairly easily should they? I will be gentle so as to not shear the head off

[LeeT5]

Yes they will come out easy if torqed in correctly.

Yes. There also 'stretch' bolts for a reason.

please explain why. most shafts have a m20 bolts. its only a driveshaft at end of day.

It may only be a drive shaft but you still don't want the bolts coming undone.
Basically, the threads on the bolt are a tiny bit closer together than the threads on whatever it's going into. as it's turned in, it stretches out and locks in place. The bolts should only be used once because once stretched and undone, they will never return to the pre stretched state. Therefore, when you retorque there will not be as much preload on the bolt and the risk of the bolt coming loose is greatly increased.
Don't ask me why Volvo used stretch bolts, how should i know that? Fact is, they did and the problem is, ppl don't heed the rule that you can only use a stretch bolt once and thus they reuse them. Obviously, that's why they keep coming undone, no matter how matter times you re torque them.

The reason for using XC90 bolts is obvious. Due to the large rubber and the 15Nm of increased torque the chances of the bolts working loose are reduced dramatically.

It is also important to note that over tightening the bolt will have the same affect as re using or under tightening.

I was thinking that martin, this problem is new to me but ive had mine apart lately as my cv had split a boot. I used oe replacements as things aren't ment to be rock solid,a cars geometry is to flex a little in the right places. I agree with using locktite as toyota's are full of the stuff. It still gives the flex along with tensile strength.
