Hi all!

I’ve just been cleaning up the CV joints and noticed that there is some wear on the shaft bearing journals.

I’ve had a measure up and the diameters, and the area inboard and outboard of the bearings is 1.249”, so assume that the ID of the wheel bearings is 1.250” to give a clearance of a thou?

Having measured in various positions on both CV shafts, the minimum diameter is 1.241” , so, 0.009” down on nominal size.

I can’t find a tolerance for the shaft diameter, but assume that this wear will make the CVs scrap?

Any thoughts.

Cheers!

Outer ones for disc brakes? (Feel free to ignore that as a daft question)

 

You might get away with it as the inner races are clamped by the hub nut - or that might be a pointer to the cause. Loctite style remedies are also available. Though if splashing out on new bearing is what led to your discovery you might well be better off biting the bullet and not taking chances with what you've already spent.

Yes, sorry, I forgot to say, 1991 Cooper with 8.4 discs!

I think I’m going to replace them as I’m not going to use loctite or risk more damage in the future!

They must be a very neat fit, even with 0.001" 'wear' they are scrap.

OK thanks Moke Spider, that’s definitely confirmed that they are scrap!
