Owen Posted June 4, 2001 Share Posted June 4, 2001 Thanks to all who have told me that the 280Z stub axles are best because of their strength. But what about 280ZXTs? I know these need a little work but will fit in the 240Z carrier. Are they significantly weaker? I would assume the things get stronger and beefer as the years go on. Thanks.

jeromio Posted June 4, 2001 Share Posted June 4, 2001 Since the ZXT stub has the same diameter and number of splines as the 240, the argument is that they're weaker. This makes it incredibly easy to use the ZXT CV halfshafts on a 240. Quote Link to comment Share on other sites More sharing options...
Owen Posted June 5, 2001 Author Share Posted June 5, 2001 Ahh, that's right, the 240Z stub works with the 280ZXT comp. flange. Interesting how this older car is even stronger than the newer ones, the ones that fit at least. Thanks! Owen Quote Link to comment Share on other sites More sharing options...
jeromio Posted June 5, 2001 Share Posted June 5, 2001 Just to make sure there's no confusion: The general agreement is that the later 280Z stubs are the strongest - hence the group purchase on the weld-on flange adapter to allow for CV axles with 280 stubs. Personally, I'm using the CVs with the stock 240 stubs - it was easier and I don't plan on running 500hp or slicks. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 5, 2001 Share Posted June 5, 2001 Jeromio, Was there anything else involved if you use the 240z stubs and Cv's? I need to change to a R200, and if its not a major undertaking, I'd change to Cv's at the same time, same deal here, I won't be running that much HP (probably 350-400 tops when I get around to phase II of the project) or slicks.

jeromio Posted June 5, 2001 Share Posted June 5, 2001 I got all my info from Terry Oxandale's site. Basically, you have to come up with a way to seal the inner bearing. The solution I used was a stock 280ZXt seal with a piece of rubber to make up the difference. I went to the home center and found a rubber plumbing coupling - it was the center part of a PVC shower drain . I used that along with some of that plumber's cheater black rubber tape stuff. You stretch it, wrap it around, it sticks to itself and then shrinks back a bit. It sounds cloogey, but it ended up looking pretty robust. The other 2 methods are to either use an R200 pinion seal with the outer rubber removed (I couldn't get this to go in the carrier no matter how much of the OD I ground off), or cutting a "ring" of PVC pipe with a section cut out to make it the correct OD.

Guest Anonymous Posted June 5, 2001 Share Posted June 5, 2001 Thanks, yeah I got to reading Terry's site last night about it. I saw he used a bushing in that one method. I may try it, as I really don't want to have to worry about U-joints. The outside 240z stub axles and flanges bolt up to the CV flange (on the wheel side) as is? Thanks for the info.

pparaska Posted June 5, 2001 Share Posted June 5, 2001 The details I have are at: http://members.home.net/pparaska/240ZCVHalfshaftConversion.htm Other than the inner seal at the companion flange, and the swapping of the dust sheild on the companion flange (from the 240 part to the 280ZXT part), it's a bolt up. Assuming that your CV shafts don't bind when you install them. I've heard of two people this happened to : Greg Kring, and now DavyZ.

DavyZ Posted June 5, 2001 Share Posted June 5, 2001 No, that was someone else--I had the leaky rearend remember? No biggie, but not me. Quote Link to comment Share on other sites More sharing options...
