Rear Diff makes a high pitch noise with throttle applied at 40+ MPH
In 2wd problem starts at 10mph w foot on gas. When I take foot off gas or put into 4wd the problem goes away. Sounds like I am driving on rumble strips on the side of the highway. I have had this 08 suburban in the shop 5 times this year. Just had a bearing replaced and the truck just hit 90k miles.this is my 2nd suburban and both are falling apart at 85k and I did all the recommended maint.

I have had this howling noise coming from the front end since about 90,000 miles but very seldom do I use the 4 wheel drive and if I do it is 4 auto so it has lasted about 55,000 miles so far making this noise but now if you put it in 4hi the noise multiplies 10 fold and it didnt use to do this
Excessive noise coming from the front, end gets really loud when in 4 wheel drive. Also 4 wheel won't disengage until you come to a complete stop. Have not figured out correct repair yet.

Every once in awhile when I turn (either way) it makes a weird sound and feeling like there is a flat tire. Tires are fine and have been balanced.

Drive train bearings grinding into its own bolts. Entire axle rotates full turn after put into park. Loud clunk when put into drive from reverse. Do not want to take to mechanic. Suburban is worth less than the cost to repair it.
10/29/2013: Had auto ride go out in rear-end at 135,000 miles. Had my mechanic check for "howling" sound in rear end thinking possible wheel bearings. He took a scope and said it is definitely coming from the rear drive pinion gear bearings. This will be the 3rd time fixed. Car is all highway miles. Transmission guy I spoke with said he "....is seeing more and more of these things and is not sure if is caused by the fluid or poor quality of parts...." Going back to dealer to rip them a new one, if that doesn't get me anywhere, than I will go to a transmission expert and have them replace it. The non-GM transmission guy said expect around $1,200 to $1,500 for repairs. (previous repairs were covered under GM 100,000 mile warranty) so I don't know what they even charge. I would guess the factor of "pi" (3.14159265359.....)

Differential is noisy and would grind when you let off the gas. Complete master rebuild kit is required to fix.
Front diff noise when the four wheel drive is used (30 thru 50) miles an hr.fix is to re build front differential.

Front end Humm or grind when turning in 4hi ... only when turning when driving, nothing when stopped no noses. Really quite an smooth 2hi
A thumping noise in my front end. Even when you go to right and left high-speed and low-speed it'll do it
The drive shaft just spins in 2wd and makes a loud banging noise and suburban won't move unless suburban is in 4 high or 4 low I'm told the rear differential is no good and is going to have to be changed

Started making a mid-high pitch whine when accelerating or maintaining speed above 40mph. Stopped when letting off accelerator. At lower speeds it was a lower pitch noise. Replaced differential assembly.
