My 1997 gmc jimmy (s15) has a vibration at low speeds, goes away at around 50mph. The vibration sounds like rolling a gear on a hard surface. This vibration will also go away when you put it into 4 wheel hi. this jimmy has push button 4wd. Any answers would be appreciated. thanks.

SOURCE: 4 wheel low works but 4 wheel high does not.

sounds like the encoder on the side of the trans on the drivers side

SOURCE: 1995 gmc jimmy will not shift out of 4wd high

sounds like the vacuum lines are either pinched or the vacuum pump is shot. try getting a mechanic look at the lines on and around your transfer case... also try checking the fuses for the 4wd selector. let me know how it goes

I recently took my vehicle to a transmission shop and they had to rebuilt the transmission right through. I was recently told that the transmission is a common problem in these vehicles. Sad that GM can not fix or recall the transmisison since there is a problem.

Check the switch on the transfercase remove the vacume lines if there is oil in them the switch has to be replaced and the lines should be cleaned out you should also check under the battery tray to make sure the boot is not ripped that controls the leaver to engage the front axel

This is your one of your axels.. they are damaged inside.. Get them removed asap it can cause major damage if it brakes loose..each axle costs about $90-100
