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.

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 " 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.....)

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.

Makes grinding noise when pushing brakes. This is the 3rd time going to the mechanic. Each time they said it was something else. Pitman Arm, Brakes now Barrings.

When going 50 mph rear end makes humming noise
1999 Chevrolet Suburban 1500- 2WD185,000
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.

Differential is noisy and would grind when you let off the gas. Complete master rebuild kit is required to fix.

I too have developed noise in the rear differential area. going to have the wheel bearings changed. hop that fixes the problem.
Strong humming sound on front Driver's side....very "heavy" sounding - almost as if we were driving in low gear. Took to dealership and they just called letting us know that the wheel bearings out going out on both sides. I am hoping our extended service warranty will cover the cost.

When I bought the truck used, the rear end made noise for 4 years. Then it started making a hard 'clunk' when making a hard left turn. The 'clunk' got more frequent. Shop inspection show the spider gears in the rear end were very worn, then they finally slipped and started breaking teeth off the gears. $840 to repair.

Outer pinion seal was leaking very slightly, but I caught it early enough and it was relatively inexpensive to replace (~$180). Mechanic said unit still had plenty of fluid so I attributed it to normal wear and tear on a 6 & 1/2 year old truck. 4 weeks later and 450 miles away from home, the rear differential was howling so loud car needed to be dropped off at a local aamco. Got the dreaded call today that the rear differential was shot and required complete replacement with a remanufactured unit ($2800). Clearly that leaking gasket was not simple wear and tear but a predecessor of impending doom in the differential. Warning to all 2007 and 2008 suburban owners....sell as soon as your ODO turns 100k, if not sooner. (especially if your rear differential seal starts leaking)
Noisy rear end and metal shavings in oil, noise from outer ends of axles and pinion area. Not fixed yet.
