stagmatt Posted May 1, 2011 Share Posted May 1, 2011 Hi, can anyone here quote/measure lengths of the Z31 300 ZX Turbo half shafts? I am trying to find out if they could replace the Datsun UJ half shafts I am currently using on an exotic Triumph/BMW axle conversion. I would need the lengths fully extended and fully compressed, both LH and RH side (slightly different). Length between wheel flange and the face closest to the diff seal is what I would need (or to end of stub shaft, quoting stub shaft length). Any help much appreciated! This forum is a real helpful source of info. Thanks, Matthias PS same request will go in the 300ZX forum, hope this is OK. Quote Link to comment Share on other sites More sharing options...
Nigel Posted May 1, 2011 Share Posted May 1, 2011 I can't tell you the lengths, but keep in mind that 240Z guys do use the Z32 Turbo CV axles to replace the u-joint axles. However, the outer CV joint bearing cage needs to be flipped to effectively shorten the axle in order to make it fit. So, if you have someone give you the lengths of an unmodified axle, it may appear too long. Nigel '73 240ZT Quote Link to comment Share on other sites More sharing options...
stagmatt Posted May 1, 2011 Author Share Posted May 1, 2011 Nigel, thanks for your comment. Yes, I know about the flipping. Are you sure the shafts come from Z32? I thought it needs to be Z31 Turbo. Are they identical? Matthias Quote Link to comment Share on other sites More sharing options...

SATAN Posted July 9, 2011 Share Posted July 9, 2011 (edited) Long one At rest = 21 1/2" Extended = 22" Compressed = 20 1/2" Short one At rest = 20 3/8" Extended = 21 1/8" Compressed = 19 5/8" These measurements are from the mating surface of the companion flange side, measured out all the way to the very tip of the input shaft. They are not EXACT, but I would trust them within 1/4". I measured them with a tape measure while resting on the floor, then in a vice pushing down on them, then pulling up on them. These are normal 84-89 turbo 300zx half shafts. These are not the NA shafts and these are not the 88 shiro special half shafts.
