Has anyone rebuilt an ax 15 on their own?

My tranny has been grinding when shifting into 3rd, and I believe it is the syncro. I've already replaced the clutch, clutch master cylinder, and slave and it still grinds. Has anyone rebuilt one of these on their own, or is it better to take it to the shop? any help would be appreciated

I know t can be done there. If you google AX15 rebuild you may come across the online manual step by step. But I always like to know its been done right the first time. I would take it to a good trans shop have them rebuild it for you.

They are easy to rebuild. You need some gear pullers though and a real good set of snap ring pliers. If you dont have about 40 hours to spend on it then just go buy a used one on craigslist for $500 and sell yours as one that needs a rebuild for $200.

I've rebuilt my engine, t-case, and axles, so I do want to try rebuilding it, I have a friend that has a master rebuild kit for an ax15 that he said is mine. I've just never rebuilt a tranny before

It really is not that hard. Here is an AX5 I rebuilt before realizing what a waste of time that was and swapping in an AX15 3-4 months later. I opened up my AX15 too, but it was good and did not need a rebuild. The AX15 and AX5 use the same design, except the AX15 is a lot bigger and stronger. Basically all your gears are on that shaft. You have to pull them off to replace bearings and syncros. It is time consuming, and basically like a giant puzzle if you cant tell by looking at it. Good times though.

Well I won't have the time to do this for at least 2 weeks, but when I do get around to it, I'll have another thread going

I will say if you aren't good at taking things apart and putting them back together again then don't attempt it. It's not that hard, but a forum won't get you out of your transmission being in a bunch of pieces if you aren't good with your hands.

Jeep AX 15 Manual Transmission Service and Repair Guide | Free eBook Download I found this page and downloaded the file, it seems like the ax-15 really isn't hard to rebuild. I'll rebuild it when I know I won't need my car for at least 3-4 days
