Yes lubricating bolts does make a difference to the torque settings, you can still apply a smear of lubricant - I do, however take into consideration this link provided by T-cut: https://www.engineeringtoolbox.com/t...ts-d_1693.html

Thanks Mike… that’s a hell of a reduction in torque, isn't it… but the idea of tightening a dry bolt really grates, even when it’s apparently the right thing to do.

Not sure what to do now, though – the easy way out is to get the tyre place to do it, but I could buy a 19mm impact socket and apply the breaker bar again.

Knowing my luck, one of the @!* wheel bolts would snap though… happier for that to be the garage’s problem

Grateful to T-cut for the link, as it might explain why I ruined a thread some time back when using my torque wrench. Now I just smear them with a little grease and put them on with my airgun without using the torque wrench. Never lost one yet.

Roger, check the size of your wheel bolts - 19mm sounds too big, mine are 17mm.

Keep well

Just don't do that unless you want it bent.

Quite right - the 19mm was the big impact socket from my late lamented M3's wheelnuts, which I'd hoped would fit the tractor


Thinking about the grease... fine if you do it all yourself, but once it's on it's on, and what about when you take the car to a garage for new tyres... doesn't that risk them overtightening them...?

True, but I always get the garage to fit the tyres on the rims and mount them myself unless I know the place, or just tell the fitter to reduce torque by 30% or whatever T-cut's link suggests and check once home. Pretty sure I've heard other owners say they torque them up themselves rather than trust the fitter's airgun.

Whenever I've worked on a car with dry wheel bolts they seem to be awfully tight and often loosen (with scaffold pipe) like a .303 going off. God help those who get a puncture with dry bolts. Never get this rifle crack sound if the bolts have been greased but I do carry a length of pipe in the boot as I know the provided tool is totally useless and even a wheel brace is inadequate.

Keep well

Right, that's interesting. Yes, a scaffold pole AND the breaker bar sounds about right Well, I've been meaning to get the 4W alignment done for ages, so it's booked in tomorrow, with a request to re-torque the bolts on all wheels - this is a small local independent, not the people who tightened them up in the first place

My thinking is that if I tighten them up using only the toolkit wheel wrench,
then if I have a puncture I'll at least have a chance of changing the wheel.

I jacked Mo up from the front jacking point once. The undertray was removed.
She slipped off the jack and put a nice V shaped tuck into the radiator, which then lost all coolant.
Replacing the radiator is a much longer story

Nowadays I jack up from the sides and put two pairs of bricks under the wheels. Then I jack up further and put axle stands under the sill jacking points.
I've seen Trikey puts axle stands in the same place. Make sure everything is level though.
For changing wheels I use the scissor jack. I have one from Tset (416) and one each for Mo and Kim.
I have one good set of wheels so have to swap them over regularly depending on which car I'm using.
Two sets of low profile tyres that never, ever stay inflated, so it's the high walled tyres I use.
And so to wheel bolts.
There is always one that refuses to shift. I now use a Millwauki to take them off.

OK... alignment all done, wheels swapped & all 4 torqued to 120NM.


The guy said my wheel bolts were getting rounded (200,000 miles' worth of butchery I suppose) so I should get some new ones.


Anywhere anybody would recommend for buying them? I don't want locking ones, really, just plain...


Thanks
