Cross threaded wheel nuts

[rs-concepts]

1997 C180 Elegance

Hi, I have just returned from my local kwik fit, I asked for a new tyre but returned with the old one still attached and a cross threaded wheel nut on the front near side. Cheers guys!

Does anyone know a way of removing a cross threaded nut?

If the thread on the Hub is damaged aswell is it going to cost a lot to replace?

Any help would be great. Thanks, Rob

Don't understand this, surely it could only have been cross-threaded when putting the wheel with new tyre back on?

Presumably your car has wheel bolts rather than nuts. In which case the thread in the hub is damaged, not sure if this could be safely repaired with a helicoil ... or whether you'd need a new hub.

This is easy enough, the bolt will have to be undone with force until it shears off.
The hub can then be removed and the remains of the old bolt drilled out.

With a bolt, it is no use using penetrating oil if it is done up tight, as it will not get to the threaded part.

I do agree with you and hard to understand, a bit of a mystery how this could came about

If Kwik Fit have cross threaded the nut , take it back to Kwik Fit and make them put it right ....

Could be expensive and if it's not your fault , why should you pay for it ?

Rob said that they could not get the bolt out ????

Wondering, if you haven't removed the bolt, how do you know it's cross threaded. Does it look askew? And if they didn't replace the tyre you asked them to what did kwik fit actually do?

Yeah but he says ' Cheers guys ! ' , which suggests to me that he is saying Kwik Fit did it ...

I don't know ....

Sorry ...

The onus to repair is on the person who fitted said bolt. This I know from bitter experience. 4 hours of drilling at my expense when I sheered a bolt off.

Maybe the guy who put the wheel on was suffering from "bitter" experience

A new hub with bearings is about £130, if the bolt is really criss theaded that will be the best option. The only other one is to weld the hole up redrill and tap.

No, whilst a helicoiled repair is strong it is completely unsuitable for this application - unless the hub is clean with no damage to the threads then it's a new hub I'm afraid (assuming that the hub doesn't have captive studs which can be knocked out)

Never in a part that could have (almost certainly was) heat treated .
If this hub is the same as later hubs then it is extremely skinny -

In my experience its almost impossible to cross thread a wheel bolt if you start the first few threads with your fingers. If on the other hand you stick it into the socket of an air wrench set on a high torque and push it in the general direction of the threads in a hub then maybe the result will different. I know where I'd put my money on what happened.

But how come it's still got the old tyre on?

 

[television]

I think that the problem now is that if the tyre was fitted 2 years back, it would be hard to go back and complain to who did it last

 

[grober]

Double Post Sorry

Sorry gave the impression that it was KwickFit were the culprits on this occasion it was maybe done on previously? . HOWEVER the other possibility is that in attempting to remove this bolt "from the off" someone got their wires crossed on the settings on the air wrench and attempted to tighten rather than loosen the bolt? Almost certain that the damage will have been done with an air wrench-great tool in the right hands BUT--------??

That couldn't cross-thread it. And it couldn't tighten it any more than they would normally tighten wheel bolts.

Are you just guessing it's cross-threaded? Perhaps it's seized - this is a much more common problem.
