squeaking sound when moving forward going over 25 mph.

[Rick27]

Can someone help me out please? I'm new to the forum. I have a 2003 GMC Yukon 4 wheel drive. I don't have power to going to my 4 wheel drive switch and I already changed out the transfer case sensor. Hoping that would fix the problem. The other issue that i'm having is, when I'm driving over 25 mph, I start to hear an annoying squeaking sound that also sounds like I'm crushing soda cans. Could this be a sign of bad wheel bearing or is from my transfer case? Please any help to troubleshoot these issues will help.

Thank you in advance.

Rick

Sure sounds like bearings. When traveling straight, on flat surface, move the steering wheel slightly to the left and right and see if noise changes. If turn slightly right then you are loading the left front bearing and vice versa.

It is likely your hubs. Jack the front end up and shake the front wheel. If you can shake it then the hub bearings are shot. The grinding metal rough moving feel if you spin it is also a dead giveaway but shaking it is the main deal. If its a solid hub the wheel wont shake at all. If the hub is on its way out there will be a lot of slop as there is no grease and its all metal on metal with no lube. IE the bearings are slowly being pulverized.

This is not always true, I`ve had bad hub bearings that were as tight as a new one but were bad.

X2. Can be tight but make the noise. Rick27 never posted back as to what he found. I hate that.

I had a similar problem with mine and ended up having a bad u-joint.

might want to check the fuses on the 4wd as well.

A bad ujoint will often PING when going from reverse to drive, or vice versa, usually due to the bearings being completely pulverized and the 1/4" of slop left in the ujoint as a result. Sometimes that will cause the traction control light to go off when the slip happens when going from reverse to drive. Also, at highway speeds you will have a horrible drivetrain shake which resembles driving on mini rumble strips. Sometimes they squeak like crazy as well.

Thank you all for the quick response. I haven't had any time to work on the truck. That's why haven't posted any results. I really appreciate you all responding to my topic. I did buy a pair of hub assembly from 1AAuto and I'm planning on installing them this weekend. Are you any of you having issues with transmission leak coming from the bottom of the dip stick hose? It's hard to get parts out here in Japan for my vehicle, so I have to order everything online and wait. Thanks again everyone.
