Sprint snapped wheel stud - changing halfshafts

#1 Post by Howard81 »

Hello :D

I have just snapped a rear wheel stud on my 1978 Sprint. Although the car is a late model with the thicker studs on the front, the rear axle is much earlier (around 3000) and therefore has the thinner studs. I still have the original rear axle, which was swapped as it was very noisy and a bit rusty in the cups for the rear radius arms.

Due to the faff of getting the old studs out and having to press off the rear hub I was thinking of just swapping out the complete halfshaft assemblies. How easy is it to shim up this compared to the hassle of pressing off all the hubs and swapping them over on to the original halfshafts? Unfortunately I don't have a 20T press available nor a local friendly garage that I would trust with my car where I currently live!

Many thanks in advance.

The axle you have in the car check how meany shims you have, they can be different either side, there the shims your going to use as that axle has been set up, just change the half shafts over

I think if you pull the shaft out leaving the backplate loose you can get the studs in.
It’s been a while since I’ve done them.

More faff shimming up the end float if you don’t have too.


Plus are you sure some of the old noise isn’t coming from the bearings? .

Thank you, I was unsure if the shims stay with the axle or stay with the half shaft, or had to be set up again from scratch.

Unfortunately the wheel studs on a Sprint have a metal shield over the back so you can’t just tap out the old studs, you have to pull the hub off which requires a 20T press…
