The Raven Posted May 26, 2012 Share Posted May 26, 2012 OK people. I have just tried to connect the prop that came with my TT engine and auto gearbox to the A01B diff that is on the car. I wont fit, i tried to make the rubber mount/bush from the N/A prop fit but that failed also. The prop does not seem to fit the diff at all. What is the answer to this issue? Do i just need a different prop or do i need a diff? Quote Link to comment Share on other sites More sharing options...
JamieP Posted May 26, 2012 Share Posted May 26, 2012 The 3 bolt flange on the NA diff is different spacings to the TT flange, you can swap them though. Is it the right length? just wont bolt up? Quote Link to comment Share on other sites More sharing options...
The Raven Posted May 26, 2012 Author Share Posted May 26, 2012 Yeah its the right length. How do i swap them over? Quote Link to comment Share on other sites More sharing options...
JamieP Posted May 26, 2012 Share Posted May 26, 2012 (edited) Ive never changed one, there is a big nut on the flange, i presume you just undo that. Edited May 26, 2012 by JamieP (see edit history) Quote Link to comment Share on other sites More sharing options...
The Raven Posted May 26, 2012 Author Share Posted May 26, 2012 Just been to have a look and cant see a big nut at all? I will chuck up some pics later. Now i know im not going mad! Quote Link to comment Share on other sites More sharing options...
JamieP Posted May 26, 2012 Share Posted May 26, 2012 Just took a picture of a TT6 diff i have in the garage for you, at a guess id say you have to undo this big nut in the middle to change the flange. You might be better picking up a second hand tt auto lsd though tbh. Quote Link to comment Share on other sites More sharing options...
Parry_10 Posted May 26, 2012 Share Posted May 26, 2012 yeh you have to undo that nut and change the flanges over, thats what I had to do on mine Quote Link to comment Share on other sites More sharing options...
The Raven Posted May 26, 2012 Author Share Posted May 26, 2012 Now i see the issue. I think i will price up a diff and then go from there. Thanks guys, Quote Link to comment Share on other sites More sharing options...
TheTurtleshead Posted May 26, 2012 Share Posted May 26, 2012 Yes you will probably get away with changing the flange, however you should really reshim a diff when swapping flanges. Quote Link to comment Share on other sites More sharing options...

David P Posted May 26, 2012 Share Posted May 26, 2012 Your T.T. conversion will function better with a 3.769 T.T. auto A02B and you will get more for selling the 4.083 A01B than it will cost to buy the one one need. Quote Link to comment Share on other sites More sharing options...
The Raven Posted May 26, 2012 Author Share Posted May 26, 2012 How hard is it to swap a diff? Nuts and bolts job? Quote Link to comment Share on other sites More sharing options...
David P Posted May 26, 2012 Share Posted May 26, 2012 (edited) Nuts, bolts and Allen bolts, out&in in an hour. Edited May 26, 2012 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
The Raven Posted May 26, 2012 Author Share Posted May 26, 2012 Righty so the best way out of this is a TT diff? Out of wondering whats the a01b one worth? Quote Link to comment Share on other sites More sharing options...
JamieP Posted May 26, 2012 Share Posted May 26, 2012 (edited) How hard is it to swap a diff? Nuts and bolts job? Yup, fairly easy, you need a 12mm allen socket for the back of the diff and 10mm for the drivshafts, had to remove my exhaust an all.

David P Posted May 26, 2012 Share Posted May 26, 2012 (edited) The A01B is rare and worth £100? more than an A02B. Edited May 26, 2012 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
The Raven Posted May 26, 2012 Author Share Posted May 26, 2012 (edited) Wonderful thanks guys. The exhaust is off anyway, One question are the driveshafts the same? or do i need different ones?

David P Posted May 26, 2012 Share Posted May 26, 2012 (edited) T.T. shafts are thicker and stronger than N/A yet fitments are the same for A01B and A02B, the N/A shafts will be fine up to 500ftlb?

The Raven Posted May 26, 2012 Author Share Posted May 26, 2012 (edited) NO fear there i only want stock tt power Anyone got a A02B diff? Edited May 26, 2012 by The Raven (see edit history) Quote Link to comment Share on other sites More sharing options...
The Raven Posted May 26, 2012 Author Share Posted May 26, 2012 I should also add anyone know the part number for the flange i need incase i dont find a cheap ish diff? Quote Link to comment Share on other sites More sharing options...
David P Posted May 26, 2012 Share Posted May 26, 2012 (edited) A new flange would maybe cost you more than a used diff. Any old T.T. flange would do. Used A02B diffs are readily available, yet A01B diffs are almost as rare as rocking horse facies. I don't know what you're fretting about, just swap the diff for the one you need and be £100 better off.

The Raven Posted May 26, 2012 Author Share Posted May 26, 2012 I will continue my hunt then. Just to make sure i understand correctly, a crappy normal n/a diff will do for the part i need if i cant get the a02b? Just my car is sat at my mates lock up and it needs to be out of his way soonish Quote Link to comment Share on other sites More sharing options...
David P Posted May 26, 2012 Share Posted May 26, 2012 The "crappy" A01B 4.083 N/A diff you have, is as Torsen as the 3.769 A02B you haven't, except it's worth £100 more. Wake up to winning. Quote Link to comment Share on other sites More sharing options...
straightsix Posted May 26, 2012 Share Posted May 26, 2012 If I remember correctly, diff flange will cost you about £70 from Toyota. You'll also need a new nut which is about £4. Had to buy these parts myself about 2 months ago Quote Link to comment Share on other sites More sharing options...

Wake up to winning. Now i understand, no point buying a working TT diff to steal the part from when i should swap the whole lot out and sell the A01B.
