But this might be accurate as when I was driving it didn’t feel like I had a 4.10 D35 and I noticed this at mostly take offs and free way driving(wish I knew how fast I was really going and RPM) Link to comment Share on other sites More sharing options...
Pete M Posted June 20, 2020 Author Share Posted June 20, 2020 It looks like that was the only way to get it in an MJ. find a dealership that can order up every little thing you want, regardless of it being in the official brochure. Link to comment Share on other sites More sharing options...

All on original order sheet from dealership. but, that’s a unicorn. Got a pic of the order/build sheet? Link to comment Share on other sites More sharing options...
schardein Posted June 21, 2020 Share Posted June 21, 2020 I have a D30 front axle out of a very early XJ (85, IIRC) with the V6. Has factory 3.73 gears, high pinion, non-disconnect. Grabbed it at a local yard several years ago for my eventual MJ 4wd conversion. Link to comment Share on other sites More sharing options...

I bought it as a rusted out parts truck from the original owner who never did anything but drive it. Link to comment Share on other sites More sharing options...
Green Mesa XJ Posted June 21, 2020 Share Posted June 21, 2020 I have a D30 front axle out of a very early XJ (85, IIRC) with the V6. Has factory 3.73 gears, high pinion, non-disconnect. Grabbed it at a local yard several years ago for my eventual MJ 4wd conversion. Yeah the 1986 XJ did come with 3.73, even though it’s not listed at places like Hollander as an option. MJ I’m just not sure, I think I’ve seen them in the junk yards but it was decades ago. Xj I am certain of because I bought axels off the 84-86 models with 3.73Sent from my iPhone using Tapatalk Pro Link to comment Share on other sites More sharing options...
