tkddav3 Posted January 4, 2013 Share Posted January 4, 2013 (edited) Hey guys, well....i was out in the supra last night and i might of had a female with me so we were just going for a drive. i didnt thrash the supra but i did give it some abuse and after a 2nd gear pull upto 120leptons (i did a few of these) i eased off and got back down to 30ish and heard a horrible sound! It sounds like a knocking/clunking sort of noise, it happens more and quicker the faster you go, you can hear and feel it coming from underneath the car, middle/back of the car. All of the gears select fine. i got it into 3rd but didnt want to go faster just incase but all gears worked as it should. So with my powers of deduction im thinking it might be the prop is fecked as the noise sounds like it happens on a rotation and the faster you go the quicker the rotation/sound? Or could it be the diff? Any advice would be very much appreciated guys! i havent had chance to jack it up yet and have a look. im off work sunday so ill have a look then Help Edited January 5, 2013 by tkddav3 (see edit history) Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 4, 2013 Share Posted January 4, 2013 Diff is my guess, especially if you still have a NA diff. Quote Link to comment Share on other sites More sharing options...
skippyboyo1 Posted January 4, 2013 Share Posted January 4, 2013 Diff is my guess, especially if you still have a NA diff. As above! I man had to smash an na diff with an na engine! Quote Link to comment Share on other sites More sharing options...
Havard Posted January 4, 2013 Share Posted January 4, 2013 Something doesn't sound right to me. You managed to get a female actually in the car? Without Chloroform? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted January 4, 2013 Share Posted January 4, 2013 i didnt thrash the supra but i did give it some abuse .... and after a 2nd gear pull upto 120leptons Does...Not....Compute... Anyway is it under load/off load? Going round corners have any effect? Quote Link to comment Share on other sites More sharing options...

Chris Bailey Posted January 4, 2013 Share Posted January 4, 2013 I thought the AO2B Diff is the TT LSD? Someone will correct me if im wrong (Which will be the case) Quote Link to comment Share on other sites More sharing options...

RobD Posted January 4, 2013 Share Posted January 4, 2013 120 leptons in 2nd? That's some long arse ratio's dude! Either that or you've got tractor tyres on the back! Quote Link to comment Share on other sites More sharing options...
Paul372 Posted January 4, 2013 Share Posted January 4, 2013 I had this it was the diff, drain out the oil and if there's some big chucks of metal in with the oil then bingo diff has gone Quote Link to comment Share on other sites More sharing options...
David P Posted January 4, 2013 Share Posted January 4, 2013 (edited) If it turns out you've toasted the diff, I'm about to remove a good A02B 3.769 from mine to fit a 4.083 and/or, also I'm in need of a T.T. prop-flange and a filler plug from a dead diff.

TheTurtleshead Posted January 4, 2013 Share Posted January 4, 2013 If it's the prop, I think I have a spare TT6 Prop, need to measure it. Quote Link to comment Share on other sites More sharing options...

SilentAgro Posted January 4, 2013 Share Posted January 4, 2013 When you get the car sorted.. Can I come have a ride in the car? I do have long hair so might be taken for a woman... Quote Link to comment Share on other sites More sharing options...
tkddav3 Posted January 5, 2013 Author Share Posted January 5, 2013 (edited) cheers for the info guys. i gonna go and jack the car up now and see what i can see! then maybe drain the diff oil. how much would a replacment diff set me back? haha agro more than welcome mate. just dont tell her! EDIT: ive got the car up on stands and while rotating the rear wheels, you can turn them so much before you hit resistance and there's a clunk. You can keep rotating the wheel but just have to push past the moment of resistance and then it free's. Keep going in a cycle. I've got a video of the noise do I'll chuck that up if I find out how Edited January 5, 2013 by tkddav3 (see edit history) Quote Link to comment Share on other sites More sharing options...
tkddav3 Posted January 5, 2013 Author Share Posted January 5, 2013 If this vid works, the metal clonking sound is what i mean http://s1195.beta.photobucket.com/user/tkddave/media/006-1_zpsd8db5ec5.mp4.html?sort=3&o=0#/user/tkddave/media/006-1_zpsd8db5ec5.mp4.html?sort=3&o=0&_suid=135740837440206882801477378798 Quote Link to comment Share on other sites More sharing options...
Pulley Posted January 5, 2013 Share Posted January 5, 2013 id drop the diff out and pop the rear diffplate off and have a look, the small case (A) torsen diff (B) isnt any where near as strong as the big case (B) torsen diff , so you may have stripped some teeth Quote Link to comment Share on other sites More sharing options...
skippyboyo1 Posted January 5, 2013 Share Posted January 5, 2013 I don't need to watch vid just from what U've said it's the diff. Mine sounded the same and when drained I had bits of metal everywhere!! I've done this twice! Just change it mate I wouldn't bother stripping etc!!
