Well thats the point, sure the BA will give out someday, as does the AX-15. How many post have you read where guy's need to rebuild thier AX-15, replace it or are having issue's with it. All I'm saying is why spend money because it might break, my starter might break as well, so should I go a head and replace it now? On my 89 MJ, 3rd gear was blown out of the BA at 156,000 miles, I drove it around like that for another year. Thats plenty of time to save the money and I still wasn't walking. I never did replace the tranny, I sold to a buddy who is still driving it around without 3rd gear. I mean it had 3rd, it just made such a racket putting it into 3rd, it was better not to use it. Like most, I will be keeping my eye's peeled for a good deal on a ax-15 and 231 to have them on stand-by, at least at this point I'm able to bargin shop as I don't have to have it right now. I can get a new AX-15 and 231 for 2 grand or go used for much cheaper. 2 grand is alot, but it would be new as in peace of mind. I'm not pushed, so I have time to figure it out and which way I want to go.
