Question about 2005 GMC Sierra

1 Answer

I have a 2005 GMC Sierra Z71 4x4 that recently started making a loud creaking noise in the front end. It is very loud and occurs instantly when turning the steering left or right, and also is noticeable but much quieter when going over bumps at lower speeds. At high speeds I don't hear the noise occuring. I have tried to located the source of this noise but I can't pin it down. Any ideas?

You might want to check the ball joint. None of them have grease zerks and can dry out. They will cause a noise when turning or hitting a bump, if really bad. Hope this helps.

SOURCE: The rear problem with a 1999 gmc sierra truck

do you know if you have a limited slip rear diff?
if you do your grease is worn out or if the fluid was replaced it need to have a friction modifier put in the diff (can be found at any auto part stores.)

if its not a limited slip diff you might have spider gears going bad. then you need to remove the cover on the diff and inspect your spider gears2f73bce.jpg b440737.jpgand these are the spider gears

I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.

check your wheel bearing at high speed they will make little. jack up the truck grab the tire on the top and bottom and see if you can move it back and forth if so , good chance bearing is bad

SOURCE: where is the 4x4 encoder motor sensor located on my 03 sierra

the encoder motor sensor is inside the encoder motor. the encoder is located at the transfer case. Remove the encoder and by part number 88962315 this is the sensor. you will have to retime the motor after
hope this helps

SOURCE: Ned to change the oil in transfer case

The Z71 typically comes with the auto 4wd transfer case (cannot remember the GM number). This requires AutoTrak II, which is available at a GM dealer. Do not use any other fluid in this transfer case! The previous post was correct in the location of the two plugs, but not on the fluid (the other types of transfer cases by GM use ATF). The transfer case is located under the truck right under the cab. There is a small skid plate under it, and a large driveshaft leaves the rear end of the case heading to the rear differential (axle). If you have the manual or electronic w/o auto 4WD transfer case, you can use Dexron III, but Dexron VI is a better fluid that is also now available at your local auto parts store. Again, if you have the AUTO 4WD button in the dash, use the AutoTrak II fluid from the dealer.

My wife drives a 2003 GMC Envoy and has been complaining about this same creaking noise upon breaking or going over speed humps. I researched this topic on the internet high and low and tried everything I read to no avail. I was about to give up and then realized it could be the motor mounts since when you break or go over bumps the engine does have some movement. Sprayed the most interesting looking motor mounts I've ever seen with silicone spray and the noise was gone! My wife has been complaining for years about this noise and now looking back what a simple solution!. By the way my motor mounts where not worn out, the rubber portion of the mount just needed a little lube.
