rear hub nut size...67 saloon

Post by **cheekytrucker** » Thu Mar 20, 2008 5:59 am

Hi,
I need to replace the rear bearings and seals of my 67 saloon. Can anyone tell me what size of socket I need to remove the hub nut. Also is either driver or passenger side reverse thread, if so which.
Many thanks in advance.
Glenn

The nut is 1 7/8" AF or I believe 1 1/8" BSW (Whitworth). The RH or offside thread is conventional RH thread and the LH side is a LH thread.

Unusual to have to renew the rear bearings - they usually last a very long time indeed! Why do you think they need changing?

rear axle leaking oil badly, have renewed brake shoes twice, simply because axle oil has leaked through the seals.

Seals yes - you may need to remove any 'groove' the old seals have cut in the hub to get new seals to work properly. Bearings are usually fine! But check the diff is not overfilled - and check the little breather on top of the diff housing is clear and not blocked.

Many thanks, had not thought of checking the breather.

Thats usually the reason, you get excess pressure inside the axel body and oil gets forced out wherever it can! Just unscrew the breather and soak it in some petrol then blast it through with an airline

You may find there is an invisible groove in the surface the oil seal runs on. I didn't believe there was a significant groove on mine but the new seals leaked almost as badly as the old ones. I wound up doing the job all over again, this time adding a piece of thick gasket paper as a spacer between the hub and the seal, so that the seal ran on a 'virgin' section of the axle. That cured the problem.
