Broken rear hub & replacement

[KevanP]

Hi, during a recent track day, my passenger side rear hub nut came off leaving the rear wheel with a rather large negative camber and no drive from that side. I was lucky the wheel never came off.

 

Since then I've taken it all apart and found the following:

1. Thread was stripped on the outer drive shaft, which was probably cause of the hub nut coming off.

2. The outer hub (part with the wheel studs on) the spline section had snapped. Leaving what was left of the splined section half left on the outer hub and the other half in the inner upright.

 

So I need to replace the stub shaft, due to the damaged thread and the outer hub due to the splined section snapped. Not sure yet if I need to replace the bearing in the upright, but I might just to be safe.

 

The question I've got is this splined section on the outer hub is quite thin material and I assume its a standard westfield supplied hub. I've never replaced it. It's on an SEIW ZK with Sierra rear diff/driveshafts.

How does this splined section compare with a standard ford item? Like the ones that can be bought from Burton's?

What size bearing do these take? Both from westfield and standard from ford's? Are they different? Do I have to buy Westfield parts? I assume not as these are standard ford's parts?

Any advice welcome. 

 

My Essex group have been really helpful in guidance, but thought I'd out this out there for the wider forum to view and comment on.

 

Lastly anyone else seen a similar issue?

I know when I bought my kit in 93 the hubs were exchange items and Westfield machined down the Ford ones o/d to suit the Volvo bearing fitted to the upright. The stub axles were standard Ford items.

That's really interesting, I had a hunch that's what might have been done. Worrying that part snapped....

Get in touch with @Rednop1, he usually has those parts available second hand genuine Ford. Unfortunately, newly made hubs or stub axles aren't really that strong.

 

ps: any picture of the damaged items? maybe we can get some insight from them.

Set of pics as requested. As you can see there isn't much material left of westfield are machining them down to take a volvo bearing...
