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.....................

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Could be falling edge/rising edge is set wrong. Are you getting sync errors?

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Mistakes were made, my R34 Story

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
