Re: 89 Cherokee 4x4 won't engage on the fly
You are describing badly adjusted linkage I think.
The linkage under is open to the weather and needs some lubrication now
and then, but when the tranny and t-case were removed for the slave job,
the 'mechanic' obviously forgot or didn't know how to set the gear lever
back up it would appear.
The adjustment isn't hard, but... It really shouldn't have gone out of
adjustment. That implies he forgot to tighten down the tranny mount or
didn't set the tranny square with the vehicle when he did tighten it
down. I would verify the tranny is in straight and tight first which
could be the cause before adjust the linkage or 'symptom'.
I would visually inspect the mount to make sure the bolts are tight and
to see if the nut marks or washer marks seem to be different than the
old marks.
If that is ok, then to adjust the shifter, you put it in 4 low. There
is a stop there inside under the boot and you want 1/8" space to the
stop. An 1/8" drill bit can be used as a measured spacer. You then go
under the vehicle and loosen the one bolt on the shift rod so you can
move the tranny lever so it locks into 4 low. Then tighten the bolt
back up. This should set the 4 high in the correct place.
