Thread: 217354 bush for front stub axle

Colin, is this the bush that the inner hub oil seal seats on?
A photo of your stub axle would be handy.

As I recall, the "Early type stub axle" was fitted with a replacable bush (which required heating to fit) but from Series III onwards the area that the seal ran on was machined as part of the stub axle. If damaged, you either speedie sleeved it or (IMHO and a better/easier alternative albeit at a slightly higher cost) replaced the entire stub axle.

If the seal surface is not too far gone it may be salvagable by an hour or so's work with some wet & dry sanding and then using and strategically fitting one of the double lipped oil seals.

No, the bush is the one inside the stub axle that the drive shaft sits in (or doesn't in the case of an S3 ?)

The Father-in-law was visting the other day and we were discussing the missing bush.
He thinks that the shaft being supported in 3 places (the drive flange, the 217354 bush and the roller bearing) would create problems unless there is some end float in the universal joint (sideways play once the cups are installed).
I'll have to check my parts manual to see if the driveshaft UJ was a different part number to the propshaft UJ, thinking about it one is sealed and one isn't so they will be different numbers.

A propshaft UJ has no endfloat, maybe changing to a common UJ meant that the bush wasn't needed (or could cause problems if fitted ?).
The bush seems to be difficult to obtain, I found a company in the UK that makes them but at 20GBP each.......

I've also hit another problem with using a propshaft UJ for the driveshaft but I'll save that for another thread.

I think the bush was simply omitted because it was found that no problems resulted from running without one. Unless being a real stickler for period accuracy, I would simply not worry about it being missing. If you are worried, making one should be a simple turning job, able to be undertaken by any engineering firm or amateur with a lathe.

I've been using a later stub axle without a bush for years . It is impossible to fit a bush to these. If I remember rightly that end of the stub axle has no step but has a slight taper to allow more movement of the stub shaft without touching it. The bush is a standard engineering item and should be available from any good bearing shop. W.

I just had a look at an old stub axle. There is no step.I'm sorry I should have checked before I posted. W.

Unfortunately the bush isn't available, I've tried.
It's sintered and thin wall, I could match the OD or ID but not both and they were longer than needed.
I did consider buying one with the correct ID, fitting on an expanding spigot & machining the OD then machining to length.

The vehicle I'm working on has a recess for the bush in one stub axle but not in the other stub axle (mix of parts over the years). Seems the bush was dropped during 2A anyway.
I do know the whereabouts of 2 NOS bushes at a reasonable price if anyone desperately needs them.

I think those bushes were originally for locating the Traka joints in the 80".
If fitted up nicely with U/J's they may save the spline for a bit longer in the driving flange.
