Is This Stuffed? Damaged In Transit.

[D.I.Y. Mik]

Got my diff back from sydney via couriers.

It seems to be damaged. See that bit is bent back.

Theres a new Kaaz 2 way in there with no oil yet.

Would a hit big enough to do that, damage the centre too?

If i bolt a driveshaft to that it will be bad, right?

Im very dissapointed, a diff was something ive saved $ for, for a while now and it looks broken already.

Canberra Centenary Hillclimb this weekend, wont be able to enter now.

But mainly the $1900 i just spent.

Make sure you have insurance on the couriers.

Could it have been damaged in transit, possibly. What's more likely, is that it was damaged when the person assembling the diff was installing the half shafts. They require a decent hit to get them past the circlip. Having said that, is it a big deal? I don't think so. It doesn't look too bad, and I think it will pull straight once bolted up.

I don't think a hit that big would be enough force to transfer into the diff itself and do damage, but I also don't think bolting up a drive shaft is a great idea either. I may be off on this, but I wonder If you could remove that bent outdrive and take it to an engineer to be straightened and annealed to reduce the internal stresses.

That sucks mate, but the LSD will be fine. If you know someone with a dial indicator, set it up against the flange face and rotate the shaft with the indicator against the flange that's taken the hit (I know one of the ears is bent but it's to see if the actual flange is out of alignment with the shaft, so set the dial indicator in towards the centre a little). You shouldn't see too much runout, otherwise the shaft/flange is out of alignment. 0.1mm (.004") would be a ballpark limit. If you've got a spare half shaft or can find one, just put that in.

I doubt that would have been caused by knocking the half shafts back in, probably dropped in transit.

Being cast, you run the risk of cracking the flange if you straighten it. If you do decide to straighten it, make sure you crack test it afterwards. Alternatively, replace the half shaft to be on the safe side.

Trying to bolt a half shaft onto that might not straighten it, and if so, will then subject that bolt to fatigue loading. Bolted joins rely on a good contact surface between the 2 components. A slight gap (and misalignment) will lead to broken bolts through fatigue and uneven loading under the bolt head.

As others have said, I think that the diff centre is protected from thrust loading from the half shafts, so that shouldn't have damaged the diff centre.

Certainly does suck though - hard to get good help these days

Thanks guys.

the shop rang and he said take it out and try to hammer it flat again, carefully.

It works 90% of the time.... apparently.

Ill give it a go, if it doesnt work....... new shaft.

Mine was the same when a mate shimmed my old diff... The bolts will pull it flat of you double up the spanners

Why not put a new half shaft in? I wouldn't risk it hammering it back as it could crack when on the car.

[D.I.Y. Mik]

Yeah, new shaft.

Its very strong, and i cant bash it flat.

Now i gotta find one...........

[macaroni646]

Don't the Kaaz diffs use standard half shafts? If so, ebay or wreckers should have plenty.

well that sucks. I reckon it would take a decent hit to bend that. My guess is it had something heavy on it or dropped during transit. Unless you can see a crack on the diff housing I would not worry about any other damage other than the easily replaced halfshaft. Just count the splines on the half shaft, they do vary. Or maybe award can send you one as a goodwill gesture.....

[D.I.Y. Mik]

All fixed now.

Picked up a shaft from a local import wrecker.

By the way Duncan, i owe you one for sure, you took it down for nothing, and the freight company charged a fee for being late, not actually delivering it to me, and damaging it.

So tell us when your down this way so i can buy you a case of beers or something.
