Re: Possible to Repair Synchros?
 

I had to change the chains on both my YJ and XJ within about a few
months of each other and it really isnt that tough. I did them both
from underneath so I could leave the case in.

Re: Possible to Repair Synchros?
 

Hey John, thanks. That is what my brother said he used to be able to
do on the older jeeps. (cj's) I am waiting for a little warmer
weather, to give her a try....I don't use her much in winter, just sits
in my garage (unheated...lol) I have got to get some manuals like Will
said. Sure would help on the tranny & Transfer case. I may just look
around for a used tranny, after checking the mounts & linkage. Someone
also mentioned the little vacumn unit for the 4WD doesn't always work
right on the yj's.(think there is one on the side of the tranny?) I
know I had trouble once with the vacumn unit on the front axel....I
think my Dakota has a similar set up. Don't have to lock in to shift
to 4wd?

Re: Possible to Repair Synchros?
 

The AX5 is classified as a "light duty" transmission, and in my opinion you
would be taking your chances with a used one, unless you took it apart and
gave it a complete inspection. The weak links appear to be the fifth gear,
and the synchros. Every once in a while someone posts here that they
managed to shatter fifth gear, or the shaft that it sits on, trying to pass
someone else, this in a four cylinder Jeep! Before replacing or rebuilding
the transmission, I would make absolutely sure that it doesn't have any
water in it, fill it to capacity with the correct fluid, and test drive it
one more time.

I like to replace the "small parts kit", whatever is in it, and seals, when
taking apart a transmission or transfer case. This gives you some peace of
mind, which may be illusory, but I don't mind that. If you rebuild the
transfer case in place, you are not going to replace the front seal. This
would bother me. There is a vacuum switch on top of the transfer case too,
that sometimes gives problems. There is a cable kit to eliminate the vacuum
deal, that you might like. This gives you the curious option of low range
two wheel drive.

Re: Possible to Repair Synchros?
 

You must have more flexible hands and arms than I do - it took me long
enough to split the case on the bench that I didn't regret dropping
the tc (not the tranny, just the tc). Pop the linkage loose, 6 mount
bolts and 2 drive shafts and it's out. I would be worried about
buggering the case trying to split it in place.
