I would guess you need to replace your brakes. Sometimes sound can fool you when sitting inside vehicle so make sure that is where the sound is originating from first.

SOURCE: rear brakes (driver-side) squeal after replacing rotors and pads

you need to grease the metal clips at the top and bottom of the pads (dont get grease on the rotor or pad though) and also spray some "disc brake quiet" on the back of the pads. it comes in a red can and the spray that comes out is like sticky red paint. do those 2 things and the squeals will be gone.

99 yukon denali drivers side turn signal in rear tail light not working, i replaced bulb and still nothing, I looked at the connections and wires and found nothing, front turn signal blinks fast, passenger...


The circuit board needs to be replaced. Which is the board that the bulbs sit in. If you remove the turn signal bulb. You will notice the bulb socket will be slightly burnt inside. I had the same problem with my 99 Denali and replaced the circuit board for $35.00. Now everything is fine.

My 2004 gmc sierra has a slight squealing noise when turning left


If noise is come from front end, and your truck is not moving at a stand still, it's going to be your ball joint's, bad news, if there OE there will be no grease fitting. New ones will come with grease fitting for future lube jobs on ball joint's.

2002 gmc sierra denali rear axle noies


I have a 2002 Sierra Denali, and when it was only two years old, I began having the same issue that it sounds like you guys are describing. Luckily, I had opted for the extended warranty, because it turns out that the lube "specialists" at Wally-World had topped off my rear differential with standard rear-end oil. I turns out that the Denali's differential has a special "clutch pack", as they called it, that requires a secial, senthetic (aka: very expensive) lubricant. The **** WalMart added contaminated the diffy's oil, and caused the clutch pack to fail.... basically it started locking the rear axles, and not allowing one side to rotate at a different speed than the other, as is required in turning.
Well, it took the dealer nearly a month to acquire the neccesary parts for the repair, and as for the cost? Only a minimal deductible, and the dealer assured me that the $1800 extended warranty had paid for itself.... nearly twice!!!
WORDS OF ADVICE: If you own a Denali with AWS, Always instruct the lube guys not to touch your rear differntial! And have your certified GM mechanic check it at recommended intervals.
