Anyone had this issue with CV Propshafts?

If you are only repairing 1 thread (what's the others like) then Helicoil it 5/16th UNF. The hole needs opening to .328 thou tapping size (the stripped hole is likely to be 5/16th which is .312 anyway) but the main problem is keeping the drill or more especially the tap to thread for the Helicoil square at 90 deg in 2 planes. Not so easy at the side of the car kneeling down. !
These studs have only about 5 thou clearance on the hub boles and if you are clumsy the stud can be put in with a lean...which then stops you sliding the hub back over the other 5 studs ! If you need to do more than 1 (surprised if you don't) then make a jig up so you can drill through and tap through square.
There are maybe a dozen threads on this in the search function...go on extend yourself, I'm not sure you admitting to being lazy cuts the mustard with continuing to receive support. !

Thanks Micky, I will keep you posted!

Just on this Micky, would I need to buy a new bigger stud for the newly tapped hole, and if so, where can I find them?


thanks

CDD sell 3/8” studs Chix and can lend you a jig to fit them I believe.

Chix,

I used their kit to do mine a couple of years ago. It was easy-peasy with the trailing arms in situ on the car, and everything was in the kit that's needed, even down to grease & thread lock.

That is great fellas, thank you. I have emailed them.


might as well do both sides while I am at it, seeing as though I have got new drive shafts coming as well.

That is why I love this forum. Really helpful and patient friends, with the knowledge and the direct link to the resources you need.

This has been the perfect response guys, thank you.

Did the whole lot! Despite some people saying it was easy/ straight forward, it wasn't... but it's done, and they're on!

Nice repair of the studs… but the face is showing some corrosion…. Best to clean that up too.
Only then can the joint & loads be transmitted as intended.

Already done mate!

Drove so beautifully up to Newbury and back, chuffed with that fix!
