TobyMellin Posted October 28, 2016 Share Posted October 28, 2016 After spending a good hour or so searching, I can't find a definitive answer. I have a 2000 Defender TD5 with a banging rear diff. I've managed to find a guy locally who sells diffs from 300tdi's and TD5's, except the TD5 diffs are twice the price! Is there any difference? Will a 300 diff go straight in and accept the half shafts? Thanks in advance Toby Quote Link to comment Share on other sites More sharing options...
muddy Posted October 29, 2016 Share Posted October 29, 2016 Yes, as long as you get one with a 4 bolt flange, i.e. The discoverys front diff. Quote Link to comment Share on other sites More sharing options...
western Posted October 29, 2016 Share Posted October 29, 2016 only if both rear axles are the same type --- Salisbury rear on 110's on a 90 it should be a straight swap. 1 Quote Link to comment Share on other sites More sharing options...
Snagger Posted October 30, 2016 Share Posted October 30, 2016 Ralph is right - Muddy's advice assumes you have a 90, in which case any 24 spline long nose Rover diff will fit (any 300Tdi and later Discovery, RRC or 90 diff, or any 24 spline 110 front diff). If you have a 110, you need either the Salisbury diff if you have an early Td5 or the short nose 4-pin Rover diff if you have a late one. Any Tdi or earlier 110 rear diff will do for the Salisbury, and I think the 4.2 P38 shared the same rear diff as the later Td5s and TDCI 110s.

muddy Posted October 30, 2016 Share Posted October 30, 2016 Correct, I just took it as a 90 due to his sig. Quote Link to comment Share on other sites More sharing options...
TobyMellin Posted October 30, 2016 Author Share Posted October 30, 2016 Mines a 2000 90 TD5 with a non-Salisbury rear axle. I just wasn't sure where there were any ratio differences and the reason for people charging so much more for TD5 diffs over TDI ones. Much appreciated!

western Posted October 30, 2016 Share Posted October 30, 2016 90/110inc td5 use the same axle ratio of 3.54:1 not sure if that changed on the Tdci [puma] engined defenders. Quote Link to comment Share on other sites More sharing options...
Snagger Posted October 31, 2016 Share Posted October 31, 2016 There are minor detail differences, such as how the cross pin is secured - TDCIs use a roll pin at one end through a drilling in the carrier and cross pin, while older diffs used far superior circlips at each end. All you need to worry about is making sure it is not a modified diff with altered ratios and making sure it is 24 spline. Apart from that, buy the best condition and don't worry about the age or donor vehicle spec. Quote Link to comment Share on other sites More sharing options...
