Replace the vacuum motor. It is easier and faster. I doubt you can get parts to repair it anyway.

No 4wd


Most common problem is located under battery tray. There is a vacuum supply coming from top of Trannie going to a plunger style actuator that pulles the cable to activate the front diff. Either check for vacuum and fix or I've relocated plunger to top of motor so I can clamp with vise grips to activate 4*4

Look for a vacuum leak. Check all vacuum lines for damage or disconnected hoses and t fittings. Could be a plugged pcv valve.

1998 gmc jimmy you here the 4x4 ingage but the front wheels want pull


Hello Bj.

This is a common issue with the Jimmy's in that year.
Because you can hear the shift motor it likely works.
The problem is likely at the front differential. There is a vacuum actuator that has a cable that pulls on a lever which engages a clutch inside the differential tube.

This vacuum originates at the engine, goes to the transfer case. On the transfer case the is a vacuum switch which then directs the vacuum to the vacuum motor when 4x4 is called for.
You will need to check for vacuum at this motor which is located on the right front engine compartment down low. Tricky to get to but not impossible. Follow the cable from the right side of the differential if you can't locate it.

If no vacuum, trace it back to the leak. If no leak, the vacuum switch on the transfer case may be bad.
If vacuum is there, which I suspect it is, replace the vacuum motor and cable assembly.
There you are, if you have further questions, please ask me here.

Thank you for using FixYa.

I have a 1998 GMC jimmy the motor on the transfer case for putting it in to 4x4 needs to be replaced is there anything I need to know to replace it


yes
the gears inside the motor strip out because the
clutch pack inside the transfer case are hanging up
do to wear
so be carefull
you may damage the gears in the new motor
the way you can tell is to take apart the old transfer case motor and look and see if the 4 small gears are
chewed up

The problem is with your vacuum system. The hubs are operated by a vacuum pump/motor on each individual wheel. This is usually where the problem is. It's not expensive to fix but you might need a vacuum gauge/pump to diagnose which wheel the problem is coming from. Also, the vacuum leak could be from another part of the system. To know whether or not it is try your cruise control. If it works ok then its probably at the wheel. More than likely just a hose since you said it has rarely been used.
