    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

  • 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.....)

    Have a howling noise coming from rear end. I have replaced the Pinion bearing once already. Also I have a clunk noise upon acceleration all ujoints have been replaced.

    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.

    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)
