{If the hub was repalced because it cracked, fine. If the teeth on the
slider are worn than the teeth on the gear are also worn. If the chamfer is
worn or the side of the teeth are mushroomed at al than the gear should be
replced. Also, the gear will tend to wear on the side that rides against
the main bearing. This wear translates to excess play that can also cause
the popping out og gear problem. Third gear does not seem to be as critical
and it does not get anywhere near the use.}

{ I am not aware og sleeved carriers being available for the 094/Syncro
transmisions. Where can I buy them or send mine to re machined? How much do
they cost}

{Again, i am not aware of this being available for the later transmissions.
I have used them with success on the earlier Busses}.
{ Another pint, my comments were provided to help provide some diagnosis for
someone with out a lot of Vanagon transaxle experience. I am amazed at how
much time people spend playing with the linkages when it is obvious the
transmission has a problem. The only adjustment that matters on the late
Vanagons is maintaioning the abailty to find 1st and 2nd gears or having
excessive play. Any other problems will not be fixed with the linkage}.
