Jap Spec diff fitting to AE86	Mon, 28 July 2003 06:21

I've just fitted a jap spec disc brake diff (early series) to my AE86, but there seems to be a clearance problem at the support between the tailshaft and halfshaft. Is this usual or do I need a different tailshaft? Is this diffential itself longer? Cheers [Report message to a moderator]

you must have a a shorter nose diff.. in which case you will require a modded half shaft [Report message to a moderator]

Yes ... if you have ever seen the two piece drive shaft on a Jap spec AE86, you'd notice straightaway how much beefier the drive shaft is & the different lengths (not sure which one is longer though) ... same goes for the rear diff for that matter.

I got around my problem by getting a custom made 1 piece drive shaft which has worked fine thus far.

I have seen others adapt the existing two piece shaft to the car but I'm not sure how it was exactly done - you could ask Simon RX7 to have a look under his car for that matter ... Very Happy

its held in by bolts acctually.. the aust 86 with single tailshaft has mounting brackets mid way half way down the chassis for the two piece unit.. it is not used tho. [Report message to a moderator]

Thanks Guys for your thoughts. FWIW, I now believe that if I get a tailshaft from a T18 (which has the same chassis as the '86 and a longer diff) that will fit perfectly. So it's off to pick-a-part I go. [Report message to a moderator]
