#297 of 313 Re: 1997 GMC Jimmy 4x4 no vacuum to actuator. [zorad1000]

I was right. The new switch that I put in saturday was either defective or wrong. I just put in a new OEM switch and the 4wd works perfectly now. Apparently there are two different transfer cases mine is a 233-c I don't know the number of the other case. The part no. for the OEM switch is 89059420 . I will return the defective switch tomorrow for a refund. I hope that my experience with this has helped someone. Lesson learned, use high quality parts the first time. I don't know if the two different cases use two different switches or not, I'll find out tomorrow.

Check vacuum line coming off the PVC going to in front of the fire wall drivers side for leaks!

Well the actuator has failed again because of trans fluid getting in it . I guess I should have blown out the lines the first time. However I have found a manual cable shift kit for the front axle. I will install this manual shifter cable soon. the kit is available at Summit. costs about $160.

I recently had some tires swapped over from winter to summer and upon getting a front end alignment I was told 2 bolts were rounded. One on each side and one front and one rear. Is this a hadr fix? Sould I just change the nuts rounded or just change all 4 bolts. How hard is it and what do I need. Thanks Mike

#303 of 313 99 SLT front differential not engaging

The auto 4wd, the 4wd hi and the 4wd lo lights just blink until 2wd button is pushed. The drive shaft from the transfer case turns but the front differential wont engage. Have checked fuses and replaced actuator. The battery was disconnected for a good 45 mins while I played around with the actuator. The fluid level in the differential is good. Have tried to trace the vacuum line but I keep getting lost.
#304 of 313 Re: 2000 GMC Jimmy Hub Bearings [jej0426]

I have had the same problem. I just had both front wheel hubs replaced at 107K miles for $750. I had to have mine replaced because to anti-lock
brake sensor failed in the left hub and the right one was noisy. I don't think there is a solution for this problems. Just like there seems to be no solution for leaking intake manifold gaskets or the flaky fuel gauges or the failing fuel pump. The is a nice "little" SUV, when it runs!

I have a 2000 jimmy and it is doing exactly as yours did. I was wondering if you ever got it figured out. If you have any advice that would be great.
#306 of 313 2000 Jimmy Issue making turn while in 4wd

I stumbled on to this site and found it to very informational. But have searched and searched and have not found the answer I'm looking for. While in 4hi, driving up a very steep hill (it performs better) the vehicle is fine. But when I turn the corner, it hesitates as if it's struggling about to cut off or something. Another time I forgot to disengage 4hi, I tried backing into a parking spot and the same hesitation occurs. Is my jimmy sick or just too old. Feel free to be brutally honest. Mind you I just purchased jimmy 6wks ago. Trip to the folks I bought it from is planned tomorrow.
