gruntus Posted December 11, 2006 Share Posted December 11, 2006 Gents, Just been given the offer of a Range Rover 3.9 rear axle (very, very cheap). I was originally going to convert to a disco rear axle on my 90 (rear drums) but been told the range rover axles should fit. The RR axle age is unknown but being off a 3.9 must be fairly newish. The questions: 1) Will this axle fit? 2) Is the diff the same? 3) Are the calipers the same as a disco/defender and hence won't need to bugger about significantly change anything? Are there any gurus out there who can answer this befor Ralph? Let the tournament begin............. Thanks in advance.

v8bertha Posted December 11, 2006 Share Posted December 11, 2006 Yep, the axle will fit. The diff may be a 24spline jobby... pull a halfsaft out and count at the diff end. Dimensionally, the diff is the same. Just plonk the entire axle on and make sure you know what vehicle it is from when buying spare bits like disks ISTR that the rear calipers are different on pretty much every disk braked Landy. Sure smoeone will be along with part numbers soon! Quote Link to comment Share on other sites More sharing options...

Matt Neale Posted December 12, 2006 Share Posted December 12, 2006 Should go straight on remove the byast valve from the front to back on the brakes. I've got to do this job at some point soon - just a quick check then.... removing the bias valve... Am I right in assuming I can (simply) fit the axle, and plumb it in using a new brake line without a bias valve? Matt Quote Link to comment Share on other sites More sharing options...

LS26 Posted December 13, 2006 Share Posted December 13, 2006 ...>The RR axle age is unknown but being off a 3.9 must be fairly newish. >... Like, less than 16 years newish Rog Quote Link to comment Share on other sites More sharing options...
s2hotdog Posted December 13, 2006 Share Posted December 13, 2006 It will fit as long as it has forward facing shock mounts I have a 89 RR axle on my 90 and used the same half shafts Easy to do only problem I had - bloody heavy and the tee pice was imperial for the flexible hose but the axle lines are the same (I used the drum braked one) so no probs I've done nothing else to the brakes and had no problems One of the best mods to an older 90 much better than cleaning out drum brakes after every off road trip Hope this helps Steve Quote Link to comment Share on other sites More sharing options...
