manual transmission life and driveshaft play??

hey guys.. got a '93 wrangler w/ 109k miles on it.. shifting's a bit rough between 1st and second.. was wondering how long you guys clutches were lasting.. i've got the 6cyl.. also.. noticed a bit of play in the driveshaft.. heavy thunk when going between 1st and reverse.. guessing it's either worn ring and pinion, clutch, or maybe tranny.. dunno about the transfer case.. any clues?

Hey bud
Did you check the driveline u-joints (assessing the clunk not the clutch problems) On the clutch life I don't know, my bro owned my yj before me and he drives horribly and replaced the clutch before he sold it to me! Good luck
Willis

Oh by the way that u-joint is easy to replace if that is the issue!

If you are having troubles shifting only from 1st to 2nd it is probably in the transmission. Mine does the same thing (half the time I just skip 2nd and go 1st to 3rd) and I've been told it is likely the syncros in the tranny.

FYI I got over 150,000 miles out of the clutch on my Chev 4x4 (but I sold it and bought my Jeep ).

I agree with Willis91YJ, I would check the u-joints on the driveline first. If the pins in the u-joint either rust or get destroyed it can create slop in the driveline.

My 1st clutch job was around 85-90K miles. If you haven't done yours yet, it's probably ready to go. Especially if you're running big tires without a gear swap (like I was for awhile). Definately check out the u-joints like Willis said. I've found that when you go from 1st to reverse with a good amount of force in each direction, you can tell if a u-joint is bad.

u-joints are cheaper than tranny work(and easier if you do it yourself!)i would check your u-joints first.hth

The AX-15 isn't exactly known for it's smooth, refined shifting action... LOL! The 1-2 synchro, from what I have been told, is a frequent point of failure in the AX-15. Nothing double-clutching can's solve though.

Regarding clutch life, I just had mine replaced at 90k miles. It had plenty of material left, but the flywheel was glazed pretty badly (causing clutch chatter).

The thunk between first and reverse is present on my rig also. My U-Joints seem to be in good order, so I imagine it's just play in the diff and tranny. There will be play in any driveline, frankly (even my '99 Camaro "thunks" going into first gear while stopped).
