FSJ Model 20 axle question

Well, the old 258 is out of the Jeep, and the shiny new "blueprinted" 258 is ready to go in [img]/wwwthreads_images/icons/cool.gif[/img], so now its time to start thinking about the next mod, which is probably axles. Is anyone familiar with the FSJ Model 20, what I'm wondering about is if my Detroit Locker I have in the SWB Model 20 will fit in an FSJ 20. Reason being, I want to go to fs axles, I'll use a 44 up front. But, it sure would be nice to save $450 by reusing the Detroit I already have. I consider the 20 a decent setup, and from what I understand the FSJ one has thicker tubes and one piece axles.

Re: FSJ Model 20 axle question

I don't know about locker interchangability but the fsj 20 does have thicker tubes, 1 peeice axles, and is much beffer. You might be able to sell your 20 W/ a detroit for the same price as a d44 detriot and then you would have matched axles.

Re: FSJ Model 20 axle question

I thought briefly about that, but IMO the 44 is a step down from the 20, especially one with beefier tubes and 1 piece axles. The 44 will be fine for the front, but not for the back with 35-36 inch tires IMO. Anyway, we've been down this road before, I don't want to start it up again!

Re: FSJ Model 20 axle question

I could throw the ford 8.8 issue in just for good measure, and stir the pot, hehehe. Just kidding!!! You should look at the 20 on the early 80s Grand Waggys, I think they might have a slightly off set center section, but not enough to be concerned with. Im not sure if you will be able to get both axles off of the same vehicle. But I think so. I think that when the Grand Waggy went to the D44 rear was the same time they went to the driver side drop. So an early 80s ahould be the HD 20 rear and D44 pasenger side drop.
Good luck.

Re: FSJ Model 20 axle question

I got around to calling Randy's, I got my Detroit from them so I figured they'd be the ones to call. They said that the internals on an fsj 20 are the same as the CJ 20, if that is the case a savings of $450 is not hard to take. My gears will even fit if I so choose.

Re: FSJ Model 20 axle question

Jeff is right, I got a friend with an 83 Grand Waggy and it has the HD20 rear and a passenger side D44 front... im not aware of the 20 being a little bit off center, looked pretty even to me, either way nothing to worry about.

Re: FSJ Model 20 axle question

would a 2-piece model 20 have a large nut at the axle flange? Mine doesn't but I thought that I had a 2 piece axle.

Re: FSJ Model 20 axle question

brendan: from your sparse profile i assume you're asking about your j10? they have the heavy duty amc 20 with one piece axles as well. only the cj's (maybe some amc cars?) had the two piece axle.

Re: FSJ Model 20 axle question

tyhe amc 20 allways looks slightly offcentered because one tube is longer than the other.. but the pinion sits to the side, and is actually centered.
