Morning All.
I've been offered a rear axle set up from a 92 sierra 4x4 cosworth. It will include Diff, Shafts, Hubs and discs, no calipers though! all that for £50, Worth it or not, and whats the diff likely to be?
Thanks in advance.

Could be ok, depends on whether the diff is 7" or 7.5"

I would think you'll want the 7"

thats what i was thinking, but aside from seeing a few pics, i wont know till i get there!

if its a locost, im sure you can make the 7.5" one fit anyway, which would make £50 a good price i suppose. Depends on your engine, if your going BEC you may as well hold out for a 7" diff, which must be lighter.

I am going the BEC route, but maybe if i dont want this diff then someone somewhere may. Not easy to tell from the pic but what do we think this diff is then?

If it's from a 4x4 then it should be a 3.62 LSD.

The diff is a 7"

If you can get the numbers from the little tag on the top left corner of the diff that should help identify it

If it's an LSD for £50 if I was you I'd buy it.

If you look on the tag, you should see something along the lines of

83BG AA 362, the first 4 can change, the last 3 are the ratio and the middle 2 are type of diff.
If it has A's then it's an LSD

Thanks guys, think i may well just bite it and go get it. worst case, it gets sold again! he who dares wins!! (well sometimes anyway!!)

Cossy 4x4 should definately be a 7" and an LSD. In fact I can tell from that photo it's a 7" so go and snap it up.

Cossy 4x4s I believe have vented rear discs and different calipers to a normal sierra to accomodate - even more overkill than solid discs for a locost! So dont worry about the lack of calipers and try and pick up some brakes from an average disc sierra.
