Hi all – just a quick question for the forum collective.

Due to a sequence of events involving a tyre monkey with an enthusiastic rattle gun, I’ve got damage to some of the threads in both rear wheel hubs. The bolts will tighten but the threads on the bolts are being stretch in doing.

So I don’t have to replace wheel bolts each time I remove a wheel, and avoid having to replace the entire hubs, I want to try and re-cut the threads in the hubs.

Does anyone know what size tap & die I would need? And as I’ve not rethreaded anything before any useful advice/words of wisedom would be welcome (I shall obviously be consulting several videos on YouTube as well!), and apologises if this is a very novice/silly question!

Cheers

 

Re-threading is not the answer at all, you need inserts put in the hub to replace the thread, Helicoil or Keenserts (which is my favoured option). It must be done accurately or the wheel will not bolt up tight with the ball on the bolt not aligning to the ball socket in the wheel, so it would have to be done in a vertical milling machine or similar.
What you have is weak, a new hub is probably the cheapest way out.

 

Helicoil is mentioned by name in the Crossfire service manual!

 

I know but Keenserts are my favourite, I have used them in the past and they blow Helicoils out of the water in my estimation.
Whatever is used it has to be done accurately.

I would agree with the recommendation to just purchase new hubs.

 

Thanks to all for the input - looks like new hubs it might have to be!

 

With all my autocrossing and testing of the car early on, the hub threads were getting loose-sloppy and I installed helicoils in the rear hubs. Its important that you watch to see that the coils do not hit the parking brake hardware as they tend to be longer than the hub. Mine are doing fine years on, FYI. WW
