big_johnson Posted June 26, 2004 Share Posted June 26, 2004 Has anyone ever thought of swapping an older 31 spline H233B into an R50 in place of the 33 spline one? It seems like this may be a good idea, since most (all?) of the WD21's have disc brakes in the rear, and have many more locker options available. Would there be any major reason to avoid doing this? How about the ABS still working? This wouldn't be a top priority on my list, but it is something interesting to consider. Any thoughts? Link to comment Share on other sites More sharing options...
Mr. Pickles Posted June 26, 2004 Share Posted June 26, 2004 Um, I have rear drums. Wish I had discs though. Link to comment Share on other sites More sharing options...
squam1 Posted June 27, 2004 Share Posted June 27, 2004 what year did Nissan make the switch from 31 spline to 33 spline? Was it when they went to the monoframe (Nissan speak for unibody)? Or are there R50s from 96 or so that have 31 spline axles?? guess the real question would be is the rear suspension (mounts etc) all the same as well as the width of the axle. Like you said, ABS would have to be a consideration if you would like to keep that feature Link to comment Share on other sites More sharing options...
big_johnson Posted June 27, 2004 Author Share Posted June 27, 2004 Um, I have rear drums. Wish I had discs though. Didn't some older pathys have discs? Or am I totally mistaken? I could have sworn I heard a reference to the discs on older pathys somewhere. :confused: what year did Nissan make the switch from 31 spline to 33 spline? Was it when they went to the monoframe (Nissan speak for unibody)? Or are there R50s from 96 or so that have 31 spline axles?? I'm 99% positive that the 31 to 33 switch occurred at the same time as the unibody switch, so in 96. I would assume the mounts and widths are similar or identical, because both axles are still H233B's, but with slightly different internals. Maybe 88 or someone knows for sure Link to comment Share on other sites More sharing options...
88pathoffroad Posted June 27, 2004 Share Posted June 27, 2004 Only the SE's and LE's have rear discs...dunno on the spline count change year, though. Link to comment Share on other sites More sharing options...
87pathy Posted June 27, 2004 Share Posted June 27, 2004 they did several things to them over the years, some of them had 10mm ring gear bolts some had 12mm then they changed the spline count. etc. etc Link to comment Share on other sites More sharing options...
