  9" grinder and 7lb hammer, then moved to a 4lb lump hammer and a cold chisel! Plus lots of sweat and swearing! Another impossible to remove locking wheel nut. Had to use 3/4 socket - breaker bar and scaffolding pole to remove the normal wheel nuts! Why oh why do tyre bays over tighten the wheel lug bolts so much?Customer supplied a refurbished wheel at £250 1.5 hours labour plus one 230mm disc, 5 x wheel bolts, tyre valve and weights! Not a cheap job! Wonder what the cars other three wheel lug nuts are like? |

I've tried to explain to the apprentice in my local garage several times that if you gun the nuts up to 700nm then stick a torque wrench on it at 90nm and it goes click, it doesn't mean they're done up to 90. I just can't put it in words that he understands. Last time I had tyres fitted he finally got the idea. If you use a nut gun on my car, I will break your legs.
Possibly a bit excessive, but seemed to do the trick

I really think the problem with this Alfa was?
The wheel bolts were covered in copperslip!
In my own mind, this extra lubricant allowed some idiot with a brand new 1000nm plus impact gun turned up to 150psi (not 90psi) To really wind them in and stretch them!
The copper slip should go the hub face to stop the wheel sticking to the hub!
Wheel bolts should be dry and torqued up by hand!
Modern twin hammer impact guns have to much stall torque now (this type of thing is becoming a industry problem).
We often have to go out and change a wheel now for customers because they can't get the wheel off!

Locking nuts are a pain in the ar*e, a lot of the newer vauxhall lockers feel like they are made of chocolate.

On my old Alfa 146 I had a right mare getting one set of wheel bolts off (can't remember why I was doing it), so I went around all the others. It took a scaffolding bar to move them. It wasn't overtightening, but some kind of corrosion I think.

Possibly a bit excessive, but seemed to do the trick Couple of months back I had a puncture repair and they offered to take off my spare and replace the repaired wheel. Didn't see them do it but when I returned home and checked with my torque wrench it was way over the 110nm. Some years back Hi-Q used a gun on the locking nut and chewed the key, after written complaint they paid for a new set and the cost of removing old set at my Vauxhall dealership, Hi-Q lost a customer that day, never been back. |

Don't know about other manufacturers
But I have noticed over the years the stated torque figures have all risen for all model classes
And there's a wide range of torque figures also
It could be difficult for an shop to keep up to date
Don't see why they can't print it below the tyre pressure label on a pillar
Though doubt the ones who over tighten would bother to look

What's considered "correct" when it comes to retorquing car wheel nuts these days?
Picked up the truck from the local merc agent on Monday. Got presented with a form to sign. Rear wheels had been removed. They had been torqued to 600, left to sit for 3 hours and checked again. I had to sign to say I would do them again in 50 miles time
When I used to do roadside wheel changes for aa etc, we had to write on the report form that wheels were to be retorqued within the next 30 miles

I've been quite surprised that last few times I have been to my local place they don't even have guns out in the tyre bays, they do them all by hand. Very refreshing to see. And the fitters even know the meaning of the coloured dots on the tyres and fit them in the right place unlike most.
