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.

:rant:

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 ;)

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.....

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. :thumbsup:

    • Can't see that being a thing.
    • My fob has never worked, I once attempted to follow the procedure to re-key it, (I have other fobs for the car alarm thing in there). I actually have three of them. Do aftermarket alarms take over the pairing mechanism for central locking? Or do they piggyback off it? I suppose it depends on the system, right? I have four sets of keys/keyfobs. One definitely works, one I think works, one definitely doesn't work, and I have the OEM one that has never worked :p. Is this fixable/workable/whatever? I mean I know it's beyond "just clean it" but how *do* they get synced up?
    • It's actually a really weird comparison... the MX5 is on another level and I kinda question this comparison at all. It'd be closer to compare it to a GTI/Golf/Hatch anything that kicks around. NC MX5 with a turbo has the right to go up with and beat the FD RX7 or 180SX or any other JDM hero car. That's the comparison that would really ruffle feathers.
    • @MBS206 you need more shed in your life... What sort of car is your mates race car?  Hopefully he returns the favour when you're ready to get cracking on yours! None of my mates are into cars so I don't have to worry about that as a distraction thankfully.  I have enough other distractions so I don't need that one too!  Between working 6 days a week (5 1/2 really so 55 hours or so per week), both kids have basketball almost every week night (including Friday night in Melbourne - 2 hours away), my daughter plays netball as well, my sons footy has started now and I coach his under 14's side as well as I'm on the Footy club committee this year, I ride motorbikes every spare Sunday I can find, plus trying to be some sort of a husband.  Life is a busy little exercise at the moment!  I wish there were 8 or 9 days in a week sometimes!
    • Ha ha, that is very true!  I'm too scared to leave it in the position though, it tingles my balls seeing it like that!
