Anything better than sierra rear hubs?

cloudy - 25/10/12 at 11:57 AM

Just thinking about building some ally rear uprights to take an alloy sierra bearing carrier, but also quite like the idea of using the astra front hub assembly

like so:

But this yields a 4x100 stud pattern...

I'm not sure if I can even buy new sierra driveshafts/hubs anymore? Does anyone have any ideas for better sources for 4x108 rear hubs?

Thanks,
James

I think the only new cars still using 4x108 are Pugs & Citroens (most new fords are now 5x108) - anything else is just as old as the sierra

Good call, the saab part looks quite good - what are the caterhams/westfields of the world moving to?

Some are moving on to MX5

Google seems to indicate the Saab 9000 were 4x108,

I guess MX5 is 4x100 though?

I have bookmarked this. Its quite useful for questions like this

Westfield are using the MX5 bits and I think Caterham are useing BMW bits, certainly the diff if not the rear hubs.

These might be of interest, released by Hispec few weeks ago. Made for the Cortina, but i know they can do custom jobs aswell.

For 108mm hubs try Mondeo front hubs and bearings.
Very cheap new and readily available.

Also of interest - the spline on a Sierra bolt-on stub axle is the same as the Mondeo.

The Sierra's splined section is longer than the Mondeo but this could be accommodated for by using a spacer.

Thanks! Any good ideas on mounting that bearing? Will it come apart from the stub without a press so the bearing can be pre-fitted to an upright?

The bearing I have shown in the photo of the Mondeo hub is not an integral part of the hub.
It is a conventional double row sealed bearing.
I have just fitted the bearing for the purpose of the photo.

I did ease the fit on the hub slightly so that I can get the bearing on/off as this is a mock-up part.

MX5 hub upright

This is an alloy upright I made for a buggy.
It used an MX5 CV, hub and bearing.
The double row bearing is held into the flat plate alloy hub with a machined top hat housing bolted from the outside face.

So if I understand you correctly, you used the supplied double row bearing in that custom ali housing? Looks very neat!

MX5 alloy upright

Yes, the alloy plate and the top hat have recesses for the bearing.
(the bearing is not shown in this exploded diagram).
