cooke Posted May 4, 2012 Share Posted May 4, 2012 I just have one question i need to know, i have been offered an A02B diff and want to know if it is a direct fit from an A01A diff with no other mods required, ie is it just the diff needs changed, i have a non turbo auto Quote Link to comment Share on other sites More sharing options...
Josh42 Posted May 4, 2012 Share Posted May 4, 2012 I have an A02B on my NA Auto so the diff itself is fine ratio and size wise, not sure if you'll need to mod anything else? Josh Quote Link to comment Share on other sites More sharing options...
James Posted May 4, 2012 Share Posted May 4, 2012 Yes, plug and play swap over. Same 4.083 ratio and casing size. Quote Link to comment Share on other sites More sharing options...
Nic Posted May 4, 2012 Share Posted May 4, 2012 Yes, plug and play swap over. Same 4.083 ratio and casing size. The final drive ratio will depend what car the diff has come off as the auto TT and facelift TT was fitted with the same diff. Quote Link to comment Share on other sites More sharing options...
cooke Posted May 4, 2012 Author Share Posted May 4, 2012 If the last ratio is different will the diff still be ok to fit Quote Link to comment Share on other sites More sharing options...
David P Posted May 4, 2012 Share Posted May 4, 2012 (edited) A02B diff-to-prop flange is larger than A01A. The diff flange can be swapped, the proper way is to strip the diff and re-shim but if not stripped, a bodge-around is to replace the nut in exactly the same position. N/A 4AT 4.083 A01B N/A 5MT 4.083 A01B N/A 6MT 3.769 A02B T.T. 4AT 3.769 A02B Edited May 4, 2012 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
