This is not a happy post....

I pressed my new bearings in today, which went very smoothly, and as I had a few hours before I was going out this evening I thought I may as well fit everything quickly.

Passenger side went fine.

Drivers side, while doing the hub nut up through the spare wheel, I felt the resistance drop off. I can now neither undo, nor tighten the nut. Not pleased at all.

Is there anything it can be apart from a stripped nut/shaft thread? I ask to save the car from rageful angle grinder and chisel hell which may descend upon it as for the first time since I've owned it I feel like giving it a righteous kicking...!

Hi guys, thanks for the feedback - I've calmed myself a little now and realised that there are far more imporatant things in the world than a stripped thread! And having it fail at speed would probably have been a lot worse.

To tighten the nut, I just use a breaker bar. I'm a bit of a weed, so a little extra leverage seemed like a good idea, but I'm rather surprised I've managed to strip such a large thread. On the drivers side, the shaft thread is a normal right-handed one.

Thanks for the tip of trying to make the threads bite with a bit of pressure on the nut; I should have thought of that myself as something to try first.

I bought the bearing kit from TVR Parts, and they came with new nuts, so I used them. I don't want to blame the bits though until I've got it apart and found out what failed. The bearings themselves are SKF, so a good brand. I don't think the nuts are marked, but one would hope they are of decent quality too. I'll update this when I find out more though.

Thought I should update this quickly, now I've cut the nut off.

It was the shaft thread that failed, so no dodgy bits sent from TVR Parts - their good name remains intact!

And Philpot has been a gent and sent me a new stub axle, so it should be back on the road soon and I will be more careful tightening nuts up in future!

What's the state of the thread on the other side, and do you know what torque it's been done up to?
I'm going to borrow a torque wrench from work that goes up to 350Nm so I can do both sides properly. Better safe than sorry...
