eaglescout526 Posted June 18, 2020 Share Posted June 18, 2020 I kinda remember there being an axle assembly part number for 3.73 gears. I think there was five options in the digital catalog and that ratio was one of them. Link to comment Share on other sites More sharing options...
Pete M Posted June 18, 2020 Author Share Posted June 18, 2020 can you screenshot a page? car-part.com does not list such a thing and my parts manual only goes back to 87. Link to comment Share on other sites More sharing options...
jeeptec1 Posted June 18, 2020 Share Posted June 18, 2020 The elusive 3.73 gears. All my years of working on Jeeps at the dealership and owning I have never seen 3.73 in an MJ. I’ve had people say yes I have 3.73 in my Comanche or Cherokee . I run there vin on the Chrysler VIP system and check there options list. 3.07. Sorry. My experience with both MJ and XJ 2.5 L4 and 2.8 V6= 4.10. 4.0 manual trans 3.07 gears. 4.0 automatic 3.55 gears. I’ve seen a couple of manual trans vehicles with 3.55 very rare special order. I believe the parts catalog does show 3.73 . I’d have to verify at work tomorrow. Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
Eagle Posted June 18, 2020 Share Posted June 18, 2020 I have the hulk of an '86 XJ in the yard. It has a 2.8L V6, auto, and 3.73 gears. I haven't seen many '86 MJs, so I can't say that I've ever seen an MJ with 3,73s. Looks like for '86 the choices in the MJ were 3.31, 3.55, or 4.11 Link to comment Share on other sites More sharing options...
Green Mesa XJ Posted June 18, 2020 Share Posted June 18, 2020 can you screenshot a page? car-part.com does not list such a thing and my parts manual only goes back to 87. Car-part is based off Hollander parts catalog, there will be odd ball stuff that will not fit any existing category, if the inventory guy is on his feet then they’ll list it close as possible and list it in the description. If they are on their toes they’ll list any 3.73 they find with the correct number 434-01564G, 434-01433D (front axel Dana 30) , 435-01421E (Dana 35 rear), if the inventory guy isn’t on his game it’ll be listed as whatever they think it looks like with a check ratio.1984-85 xj Hollander does list 3.73, the fact they don’t list it for 1986 XJ & MJ means it was so odd ball AMC or Chrysler (depending when Hollander got information from Jeep ) never listed it as a option. I know I’ve got 3.73 axels off 1986 XJ, I’m sure I’ve seen MJ with it but wouldn’t swear to it.I tried years ago to get a build sheet for my old XJ, I was told records didn’t go back that far.

89 MJ Posted June 18, 2020 Share Posted June 18, 2020 I saw an XJ with 3.73s, but like everyone else, not an MJ. I also saw this FB know it all trying to tell Pete he was wrong. Pete, I don’t think you were wrong. Link to comment Share on other sites More sharing options...
Pete M Posted June 18, 2020 Author Share Posted June 18, 2020 Just looking for some evidence, one way or the other. can't really use car-part.com as an outright bible, it's just a reference. really wish I had a paper 86 parts manual. Link to comment Share on other sites More sharing options...

fiatslug87 Posted June 18, 2020 Share Posted June 18, 2020 From what I see in the '81-'86 & '86-87 Parts manuals 3.73 were not offered in MJs. Manuals can be downloaded in this thread (the '86-87 manual was a hard copy that I PDF'd) Link to comment Share on other sites More sharing options...

SoCalManche Posted June 19, 2020 Share Posted June 19, 2020 I think the most annoying part of watching that argument unfold was the other guy saying he trusts what he encounters himself, not taking into account that axles are swapped all the time.

Pete M Posted June 19, 2020 Author Share Posted June 19, 2020 part of it was I missed a word. the one guy said waggys and my brain skimmed over that. but in the end I was still hunting for the same page that answered everything. as I tell my eldest nephew all the time, it's important to read ALL the words. (he's a little genius and if he gets an answer wrong at school it's almost always because he read it too fast) Link to comment Share on other sites More sharing options...

Pete M Posted June 19, 2020 Author Share Posted June 19, 2020 I'm a clinically forgetful chap. I just try to look stuff up before typing and so it makes me seem more knowledgeable than I actually am. I have very much forgotten more stuff than kids today know (but it's mostly because it all evaporates so easily). Link to comment Share on other sites More sharing options...

It's impossible to know everything, and I am frequently amused by people who like to think that they do. To survive (if not succeed) in this world, what's more important is knowing where to look for information, so that you DON'T have to rely on fallible, human memory.

cruiser54 Posted June 20, 2020 Share Posted June 20, 2020 I had the priveledge of ordering brand new Comanches for myself as demos. Only 3 or so 1986 and earlier. Never saw 3.73 as an option. Link to comment Share on other sites More sharing options...

I had an 88 chief, metric tone, tow package, auto 4x4 with np242 with buckets and lighted Lund, and 3.73s with trac-lock. All on original order sheet from dealership. but, that’s a unicorn. an 84-85 xj with carb’d 2.5 and auto would be the most likely source for 3.73s Link to comment Share on other sites More sharing options...
