Thread: mix and matching hubs and stubs

Disc brake sals stubs are shorter than the drum brake variety due to a narrower spacing between the bearings, something to do with being able to fit alloy wheels. Something tells me the Disco hubs will also run the narrow spacing.

Also from memory, the half shafts are shorter because of this.

So...............would think 300TDI Defender stubs should fit as they both use the same bearings and the spacing MAY be the same as well as the hub seals should fit. Only one way to find out.

Not completely true.

My '91 drum brake Defender has the same (narrow bearing spacing) stub axle dimensions as the Disco 1. So there must be a change over sometime during Defender production.

(Also the problem with the alloy rims is the external size of the hub casting, which can be machined off to fit the alloy rims without having to change stub axles or hubs.)

It also means that just like when fitting 110 front hubs onto 110 rear stubs there is a 20mm narrowing of the track.

Can we start a table, where we specify the VIN of the vehicle (or donor axle), whether they are narrow or wide bearing spacing and the height of the wheel face and drive flange face when the hub is sitting on the floor with the wheel face at the top?

This way we may be able to sort out all the differences in a single source.
I wonder if we should also check (and tabulate) the axle halfshaft lengths by inserting a measuring stick into the diff and measuring the flange face of the hub/s?



I will complete my measurments over the weekend.

chasing the answer to my main question first.....is it OK to fit D1 rear hubs to a salisbury rear stub

i have done this already to a custom trailer axle and have towed it for a few thousand km's.

just want to make sure the bearings are sitting on the right spots......it all bolted up OK

You need to qualify just what salisbury you are referring to. Just stating salisbury stub axles is misleading.

As per the earlier replies, early drum braked sals have longer stub axles for wider hubs and bearing spacing.

The bearing spacings on my '91 Defender (Salisbury & Rover diffs) are exactly the same as the bearing spacings on the Discovery 1 hubs I have.
