4wd not engaging. Check actuator and seems to working properly. Jacked front end up and and when in 4wd the front tires spin freely. Any suggestions?


Does the driveshaft for the front wheels turn when in 4wd? The actuater might work but the diff lock for the front wheels might have broken. If the front driveshaft does not turn when in 4wd, the transfer case might be the problem.

4wd will not engage in 4HI, 4LO or Auto 4WD


most of the engine power is designed to go to, the back wheels UNLESS the transfer case is in LOCK position in 4 hi or 4 low..also was the front hubs locked in...some models still use lockouts in front..remember this also.. if most of the weight is up front as it is on pickups, the rear wheels are the least resistance for the power so they will move first unless thers enough weight on top of them say sandbags or firewood or just dead weight...(if the truck is used look under the vehicle to see if the front driveshaft was taken out..some folks do this for fuel economy purposes) good luck repost findings please...thnx

My truck is stuck in 4LO and the button in the truck dont work.


If its a push button 4x4 take it to the shop its a VERY COMMON Problem dealing with the electric.Once you pay the $400 to get it fixed get rid of the truck and settle for a Jimmy/Blazer/Bravada with a floor shift 4x4..GM had problems with the push button 4x4.DONT DRIVE YOUR TRUCK IN THE MEANTIME.YOU WILL BLOW YOUR TRANSFER CASE RIGHT OUT OF IT!

1986 GMC Jimmy 4WD problem


Rich. There is a vacumn engagement of the front differential. The switch is on the transfer case. There will be a vacumn motor(looks like a curise control unit if you're familiar with them) under the hood with a cable running to the front diff. Make sure it functions when you engage 4wd. Probably does. If not, make sure it is getting vacumn by removing the line. It should **** on your finger when covered. If this all works properly, you could have trouble in the front diff. Don't forget the simple stuff, like CV joints, axle nuts tight, etc. You're driving an 86 so I assume you have a little experience in maintaince. Good luck. TJ
