I found them on the internet somewhere & saved them because they were not in my Hanes service manual. The 89 should have an NP231 Xfer case like my 1991 so should be the same. Usually the biggest problems are the hoses get old & leak or the front axle engagement vacuum motor gets gunked up due to lack of use. I have had to take mine off & soak with PB Blaster them move it back & forth to get it working again. Now every time I start the motor, I engage the 4WD to keep the shaft in that poor design motor moving. Eventually I will replace it with a cable system like the Posi-Lok of one I build myself from plans found on the internet. The cost diffs are Posi-lok is around $2-225 vs $25-30 for parts for the home made cable.

the front axle and transfer case for your Wrangler are vacuum actuated so you may have a vacuum leak, under the hood by your windshield washer solvent there is a black plastic cylinder with 2 vacuum hoses on top, one goes to the axle and one goes to the transfer case, one of these is most likely the problem, if the hoses are fine then you may have a bad actuator on the axle, good luck.
