question about removing diff & driveshafts from a donor...
fha772 - 10/5/14 at 12:59 PM

all,

Just a quick question, which I'm sure I know the answer to...

Can I remove the diff and driveshafts from a 2wd sapphire cosworth, and still leave it on it's wheels?

I know where there's a cosworth shell, with the diff still fitted, but the lad who is selling the bits is worried that it won't still be able to keep it on it's wheels if I take the diff and driveshafts.

Cheers Frank.

The ones with bolt on shafts can be removed with the wheels on.
Push in shafts you have to take the wheels off.

Cosworth has bolt on driveshafts, so should be alright (in theory).
Might be tricky to undo the driveshaft bolts though.

I am pretty sure, but took the wheels off when I did it so not 100%.

Lobro/bolt on shafts... Yes

If you take the drive stub and from the hub/bearing, it'll still stand but if you push it around the hub flange will work loose and give comedy wheels.

So, it still needs the driveshafts bolted through the hubs to be able to push the shell about?

It's ok, because I only need the inner part of the driveshafts so I can make up some hybrid shafts to fit my Mercedes.

Not if they are bolt on. Bolt ons leave the stub axles behind in the the bearings and hub carrier.

Just cut through the drive shafts and leave the outer bits flapping about.
Just to note, the FoMoCo LSD isn't a true LSD. Have you considered finding a proper LSD?!

I've looked at a few different lsd's, the sierra 1 is very similar in size and also mounts in almost the same way.
Even though it's not a full lsd, it's going to be a lot better than the open diff I've got now.
The diff I've found is a 7.5 inch 3.64:1 bolt on driveshafts.

Edit; I just thought I'd clarify, when I said leave the wheels on, I meant leave as a rolling shell after I've removed the driveshafts and diff, I can take the wheels off while I remove the parts, then refit them.

To clarify, Cossy Sierra has bolt on shafts you can unbolt the shafts and remove them with the lobro joints and STILL be able to roll the car around.

Need to take issue with comments about Ford LSD, yes its viscous so does not lock hard like a plate diff does, it is a true LSD just set up for the road, plate diffs need setting and only work for the conditions there set for, so in a sense only ever work properly for one set of conditions unless you reset for road or track
Quaife ATB is supposed to be better than Ford viscous and less intrusive than plate
For the road Ford viscous is probably fine, on track better than an open and cost wise soo much cheaper than the others
