texasjack Posted September 22, 2017 Share Posted September 22, 2017 My 90 has a bent left rear axle. Will an 87 axle fit in the 90? The 90 is an automatic with 4.0 engine. The 87 is standard with 2.4 engine. Thank you Jack Link to comment Share on other sites More sharing options...

Dzimm Posted September 22, 2017 Share Posted September 22, 2017 The axle will fit fine however the gearing is probably not the same. If it's a 2wd it won't be an issue, if it's 4wd, figure out the gear ratios before swapping. Link to comment Share on other sites More sharing options...
gogmorgo Posted September 22, 2017 Share Posted September 22, 2017 The 2.5/manual will likely be 4.10 geared, the 4.0/auto will most likely be 3.55. I'd rather have the 4.10's. Is there a matching front axle from the '87? Link to comment Share on other sites More sharing options...
Pete M Posted September 22, 2017 Share Posted September 22, 2017 Jack, are you talking about swapping the axle shaft or the whole axle? Link to comment Share on other sites More sharing options...
Big Dan Posted September 22, 2017 Share Posted September 22, 2017 The 2.5/manual will likely be 4.10 geared, the 4.0/auto will most likely be 3.55. I'd rather have the 4.10's. Is there a matching front axle from the '87? Depends on what year. My 86 4 speed is 3.55. Sent from my Nexus 6P using Tapatalk Link to comment Share on other sites More sharing options...

Crash Posted September 26, 2017 Share Posted September 26, 2017 Figure out gear ratio for new rear axle, and find a front that matches. XJ d30 will be plug n pray Link to comment Share on other sites More sharing options...
ComancheKid45 Posted September 27, 2017 Share Posted September 27, 2017 Axle shafts will swap right over, assuming it's the same model rear end. Link to comment Share on other sites More sharing options...
texasjack Posted September 27, 2017 Author Share Posted September 27, 2017 I am swaping the axle shaft on the left. I checked the bulkhead label and it had a 4.0 engine. Thank Y'all for the help!!!!!!!! Jack Link to comment Share on other sites More sharing options...
