I Broke My R33 Gtr Front Diff :(

Hi all,

It looks like that a couple hours on the dyno were the straw that broke the camel's back....my front diff. On the way back from tuning the diff was emitting horrible sounds and after inspections it turns out we have a severely worn set of gears in it. The crown gear is missing all it's heat coating and well, is very worn down. Looks like a wrong batch of oil was used that was thin as water.

My mechanic in town has located one mob that has some 2nd hand diff innards for sale but with quite a price tag attached.

Do any of you guys know where else I could get some from, short of me putting up a WTB ad? Also, I take it that I could you gears from a 32?

....I have done a bit of "googling" but have mainly been coming across UK threads.

Thanks for your time gents

PS - car is currently in rear wheel drive "mode" with front prop shaft removed to save the diff from locking up completely or something horrid like that.

Having swapped to Nismo front/rear before i sold my GTR - no word of a lie probably the best mods I did.

The car handled so much better there is no scale of measure i could put to it thats how good the improvements were over stock/worn diffs as they lock perfectly.

Ah ok, yeh I can imagine. It would have to be as awesome as putting in new coil overs or something like that!

Only problem is that I don't really have a spare $1500 to throw at it...may have to do it later down the track.

Sounds pretty nasty with your sump!

Sorry about thread dig but could you please describe the sound when the front LSD broke?

Did it made clicking sound that you can feel while driving it?

Cheers

It sounded like a wicked set of straight cut gears ;-) No clicking or vibrating...just noise because of how the teeth were worn (no longer helical etc)

Is yours broke?

I've no idea at the moment, waiting for friend to come over and have a look at it, hopefully it's just the CV like I originally thought.

We'll see...

Well if it's clicking then there's a fair chance it's a worn CV....does it click when your driving around sharp bends/corners?

If the diff is making a clicking or clunking sound then it's bound to be in really bad shape haha

It turns out it wasn't either CV or front diff, oddly it was coilovers... Clicking sound happen when I braked it.

Oh well, all that worrying for nothing!

I am looking for a GTR front crownwheel & pinion at the moment.

Too much power to the front wheels - have broken the teeth off mine!

Already have good LSD centre - just need the gears if anyone has them spare

after changing ratios.....................

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
