tommis85 Posted June 25, 2012 Share Posted June 25, 2012 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.

XKLABA Posted June 25, 2012 Share Posted June 25, 2012 where are you located, i have a 32 front diff I am about to pull apart to change to 3.55s for my 34 build Link to comment https://www.sau.com.au/forums/topic/403380-i-broke-my-r33-gtr-front-diff/#findComment-6415065 Share on other sites More sharing options...
tommis85 Posted June 25, 2012 Author Share Posted June 25, 2012 Hey, I'm located in Toowoomba....can the internals be easily exchanged? Link to comment https://www.sau.com.au/forums/topic/403380-i-broke-my-r33-gtr-front-diff/#findComment-6415134 Share on other sites More sharing options...
R31Nismoid Posted June 25, 2012 Share Posted June 25, 2012 Upgrade it. Do it once, do it right. Link to comment https://www.sau.com.au/forums/topic/403380-i-broke-my-r33-gtr-front-diff/#findComment-6415150 Share on other sites More sharing options...
tommis85 Posted June 25, 2012 Author Share Posted June 25, 2012 Upgrade it. Do it once, do it right. You're quite right about that - but that would cost a bit eh? I dare say those gears would cost as much as gearbox upgrade gears, so around $800 to $1000ea?

R31Nismoid Posted June 25, 2012 Share Posted June 25, 2012 Yep that it would. Nismo front IIRC is $1500 (cant remember exactly, i broke my sump at the same time - which is what can happen if you break one) Link to comment https://www.sau.com.au/forums/topic/403380-i-broke-my-r33-gtr-front-diff/#findComment-6415249 Share on other sites More sharing options...
R31Nismoid Posted June 25, 2012 Share Posted June 25, 2012 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.

tommis85 Posted June 25, 2012 Author Share Posted June 25, 2012 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!

XKLABA Posted June 25, 2012 Share Posted June 25, 2012 is it the whole diff you need or the crown and pinion gears, if whole diff upgrade to something like the quafe, if its just the crown and pinion I'm happy to post to you Link to comment https://www.sau.com.au/forums/topic/403380-i-broke-my-r33-gtr-front-diff/#findComment-6415264 Share on other sites More sharing options...
Count Grantleyish Posted October 20, 2012 Share Posted October 20, 2012 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?

Moodles2 Posted October 20, 2012 Share Posted October 20, 2012 The front diff isn't actually a LSD but a regular diff, Nismo do make LSD centers though to suit.

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...

tommis85 Posted October 21, 2012 Author Share Posted October 21, 2012 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 Link to comment https://www.sau.com.au/forums/topic/403380-i-broke-my-r33-gtr-front-diff/#findComment-6588220 Share on other sites More sharing options...
Count Grantleyish Posted October 21, 2012 Share Posted October 21, 2012 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! Link to comment https://www.sau.com.au/forums/topic/403380-i-broke-my-r33-gtr-front-diff/#findComment-6588587 Share on other sites More sharing options...
Munro Posted October 25, 2012 Share Posted October 25, 2012 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.....................
