Why does my GMC Jimmy 4WD make noise?

Why does my GMC Jimmy 4WD make noise?

Noise could be many things as u-joints, hubs, brakes, tires etc so need to look under it and start checking. Also look at the transfer case fluid and change every 50k as well as trans fluid/filter. On my 2000 Jimmy, when I press the 4WD button, I hear the clicking and I feel it shift. REALLY feel it shift! Feels like I’ve got the brakes on.

How can I tell if my GMC Jimmy 4WD is coupled?

Chack the actuator (crawl under the pass side front) by looking /listening to see it the cable pulls the axle coupler. 3. Check the front axle coupler sensor (wires to it) by unscrewing and pushing the ball in) which tells the TCCM or 4wd computer that the axle is coupled for all 4wd modes.

What to do if your GMC Jimmy has vibration?

Check/change the front and rear differential gear oil and the pinion seals can leak there too. Vibration must be traced to type – tire or drive train. If the U-joints are original and have no zerks on them they may be loose. Check the front wheel bearing and tire balance.

Where is the rear sensor on a GMC Jimmy?

The rear sensor is in the transfer case. The passenger side front axle has a coupler that engages the axle to the front differential when any 4wd mode is activated and a sensor tells the TCCM computer in the cab located in the pass side kick panel its engaged.

Why does my Chevy truck clunk when I turn?

Mine in the 2010 is different and there is a huge cv looking boot and u-joints on it that were clunking on me. I replaced and it went away. I would presume you got the “updated” version if you replaced your intermediate shaft so would not suspect it to be bad. It could be that something is shifting in the suspension and making the clunk.

Why does my transmission make a humming noise?

Thanks for your question about the humming noise in your transmission. Humming noises are usually an indication of a bad bearing. If you are sure the noise is coming from your gear box and happens even in neutral, then the output shaft bearing in your transmission may be starting to go bad.
