Wheel Nut sending me NUTS!!

[Trem]

Same problem for me, just had to order a new key from McGard. Luckily I had my ID card with number on it so ordering was easy. Cost 18.00 Euros.

Yes, grease them and dont tighten very much.

The correct answer is to NOT apply any grease or anti seizing compound and torque the bolts to the manufacturers torque settings. This should mean that the bolts are tight enough to be safe, and do not seize.

If you grease the threads then any torque settings that you have on a torque wrench are not valid. You can snap wheel nuts quite easily with greased threads whilst still being under the manufacturers torque settings. Or worse still, you go for the manufacturers torque setting and stretch the bolt and reduce its strength, and then one day you lose a wheel at 70.

Things that tend to cause overtightening of wheel nuts are

1. Using grease or lubricant on the threads
2. Using an air impact wrench to tighten the nuts
3. Not using a torque wrench

And things that cause undertightening of wheel nuts

1. Torqueing up a hot wheel
2. Not using a torque wrench

Just an update, as yet NO BODY can shift this locking wheel nut because as soon as they see it or i tell them over the phone "its a Volvo!!" they cant help but Im not giving up. Friend has welder will try that next.
By the way I have been quoted £70+vat for the job

I got mine off with a socket from a Sealey SX202 locking wheel nut removal kit attached to my air impact wrench running from my compressor.

It does rely on the locking wheel bolt not having a rotating outer edge though.

Basically the removal sockets are reverse threaded and you just chose one that is about the right size, give it a quick bash onto the end of the bolt with a hammer and wind it on using the wrench and hey presto, off it pops.

Thanks Zimma but mine HAS the fecking roatating floating washer on it

So I torque them up correctly, dont oil them and come back 6 months later with a new set of bolts and a drill kit. Have you experience of getting these buggers off, because I have and all the quack tricks like welding and banging a remover over the top failed. It was smash the wheel off or drill.

hi,

i had the exact same problem with overtightened locking nuts (by volvo main dealer) on my xc90.the unlocking socket split under extreme force.last resort i took it to a mate of mine who is a class one welder and we had to weld 20mm bolts on to the end of the wheel nuts to get them out.he did this without even marking the alloys.only problem was the battery was disconnected to protect the electronics and after re connection the cd player went ballistic and knackered all its mechanism (£200 repair job) all this because of overtightening the nuts and a poor design of locking nut.i,ve never fitted a set of locking nuts since and never will.

best of luck

peter.

I got my new key and it still won't turn the locking wheel nut, it is close to becoming sheared like the last key.

I was thinking of getting something welded to the nut but I was worried about the wheel damage that may occur, is it something I should worry about or can good welders be that accurate as to not damage the wheel?

Ive had a re-read of what I wrote and want to add something about my experience in the matter.

1) Im not saying all the wheel nuts were greased, I use a smear of copper grease on the rotating ring just behind the front face - I used non on on the threads.

2) I nipped the locking nut up with a short wrench. The rest I did as always - tight to torque.

3) This is not a method laid out in any service schedule, simply my trial, error and carries no technical weight with anyone.

Before someone tries oiling the lot and saying the bastard DDN said......

As for welding, didnt do any good for mine.
