need4speed Posted February 4, 2008 Share Posted February 4, 2008 Are defender 90 axle cases/diffs interchangeable, ie if i bought a crusty pair of early axles to rebuild, could i fit 24-spline diffs into them without hassle? Or would i have to buy a pair of 24-spline axles from the outset? Quote Link to comment Share on other sites More sharing options...
sean f Posted February 4, 2008 Share Posted February 4, 2008 It is possible to fit 24 spline diff into early axles but... It not a simple as it seems. The diff just bolts straight in. To get the halfshafts to fit you will need to change the stub axles to the later (shorter type) finding the correct profiles for your axles is a bit hit and miss. I ended up sat in Brookwells with the old ones going through there parts list and looking at all of them to work out what would fit. This then means you will need to change the hubs to the later (narrower) type as well. The discs and calipers will be fine as they all fit in the same place. I found all this out after doing it myself. It was worth it on mine as the axle was in place and modified for air springs. If you are getting second hand axles then get the 24 spline ones the first time, by the time you have got all the bits to convert older ones it will probable be cheaper anyway and certainly simpler.
