Re: £100 Alfa Update
I had a similar problem with wheel nuts on a car i had bought for spare parts.
the last owner had let the garage attach the locking wheel but with an air wrench I think and had stripped the inside of both the locking tools that came with the car.
thought I would buy a reverse thread unlocking tool to get the wheels off.
kit came with 4 sizes, one of which seemed a rough fit.
to get it on I used an impact rench to create the turning motion while pushing it onto the rusty old locking wheel nut.
this did work eventually but has now left me with a wheel nut attached to the reverse thread tool. I have tried everyting to get it off, but have basically managed to destroy the bolt trying it is that tightly wound on.
So when it came to undoinf others on the car I used an alternative method.
take a decent socket making sure it is going to be a tight fit and then with a big hammer, hammer it onto the bolt, once it is firmly pushed on a fair bit you can then undo it with your breaker bar or good length rachet.
this method was a lot more successful for me as I could remove the wheel bolt from the socket once I had un fastened it from the wheel.
the special tool is still attached to the stub of a bolt which i have had no luck removing even with trying to heat it up to free it so not very reuseable, you may be better off just buying a half decent sacraficial socket to use for this job.
