Rear hub seals and bearings

Post by robinhayes25 »

I am in the process of renewing the rear hub seals and bearings on my 1957 A35.
I am running into a few problems. I am having to use a 48mm socket to remove and replace the hub nut. It's not doing the nut a lot of good. ( I live in SW France and simply can't source a 47mm socket).
I have pressed in the new seal and bearing on the right hand wheel in my vice.
The bearing fits flush when I have pressed it in using a vice, but when I try to mount the hub onto the car as it slides onto the shaft the bearing becomes proud of the hub by about an eigth of an inch and will not reset to being flush with the surface of the hub.
What am I doing wrong ? Also, is there a torque setting for the hub nut ?

My memory is terrible I'm afraid Robin but I can remember borrowing a specially made spanner for this job. I did manage to remove some nuts from scrap axles quite easily with a chisel . The nuts undid with minimal damage. Are the torque settings not in the Workshop repair manual?

The bearings are loose in the hubs due to wear, or possibly due to them being manufactured slightly undersize... Sometimes a problem with cheap Chinese bearings... Locktite Bearing Fit will sometimes fix it, though it won't fix poor quality bearings...

The manual gives no torque setting for the rear hub nuts. Just do them up tight... :whistle:

There's a PDF copy of the workshop manual in the member's area of the website if you haven't got one... :thumbs:

As Neil says, but if you strip the thread on the end of the axle that means a replacement axle !

Thanks gents for all your replies.
I have now purchased a 47m socket via ebay (arrived today).
will try it in the next few days.
BTW I tried to refit the original bearing (which was flush originally) and again as soon as I tried to fit the hub to the car, again it became proud by about an eigth of an inch.
