[928uk] Rubber CV boot

[Simon Crowe]

Hi Ken,

The shafts are not handed, but I would suggest keeping them on the same side after rebuilding them.

I think the S4/GTS shafts may be different to the earlier cars?

Cheers,
Simon.

If it’s at a slight angle it will slip and damage the bolt. When you come to do this it will make more sense as it’s not so easy to explain.

I bought a torque wrench specifically for this job a few years back, so to buy or borrow one is by the easiest option. There is a more scientific way to do the job involving weights and a breaker bar etc but I took the simple route.
