Tony240ZT Posted August 11, 2015 Share Posted August 11, 2015 (edited) I have MM companion flange adapters with an R200 and 280zx turbo cv's in my 240Z. My right side boot was torn, so I picked up a rebuilt replacement. The typical PepBoys/AutoZone don't carry these any longer, so I was happy to have found one. On the table at the shop I compared the best I could. The new one did seem a little longer there, but it also had a stronger return spring in it and the rubber boots were much more elastic, so I thought that's what accounted for the added length. I go to installing it today and it's around 2 inches too long. The splines pop in just fine and the companion flange is the same. So, the ends are identical to what I had, but the length is obviously different. I've been sitting on this shaft for a while, not sure if I can return it at this point. Given what I've described does anyone know what I have? Could this shaft be from a Z31? I may have to sell it to recoup some of my cost, but don't know what its application would be. In the picture I have the new one (bottom) that I was installing on the right side of the car and the left one (top) that fits fine.

jthom5147 Posted August 11, 2015 Share Posted August 11, 2015 It's been mentioned in other threads before: The replacement units sold by parts stores are z31 axles and are incorrectly marked as fitting a 280zxt also. However, you might be able to disassemble the one you bought and rebuild your axle, but the axles I bought from Napa and kragen were not able to be disassembled (diff-side cv joint is stuck on and no matter how hard I bang on it it won't come off, short of breaking the cv cage) Quote Link to comment Share on other sites More sharing options...

Luckily the shop still had my core. What a PITA Quote Link to comment Share on other sites More sharing options...
jthom5147 Posted August 12, 2015 Share Posted August 12, 2015 Yup. It bugs me that when they sell the axles they tell you that it meets all manufacturer's specs, but that's a lie. Quote Link to comment Share on other sites More sharing options...
NewZed Posted August 12, 2015 Share Posted August 12, 2015 A guy on zcar.com spent almost a week trying put a reman ZX booster in his Z. He got two mislabeled parts in a row. With reman parts, it's best to assume there's a problem and verify everything. Quote Link to comment Share on other sites More sharing options...
Eric JB Posted August 12, 2015 Share Posted August 12, 2015 I searched high and low for a pair of rebuilt 280zxt axles to replace my cores with ripped boots. No luck Then I searched for boot kits. I finally found them at Amazon. Quote Link to comment Share on other sites More sharing options...
