SNOW 2008 GMC Crew Question

To bump and risk partially hijacking the thread.

Any years to avoid between 2003 and present in either 1/2 or 3/4 ton Chevy's? (Yes, all Ford and Dodge guys will say ALL, I know)

Rear end issues,negative unless A) someone was stuck more than once and fried the rear end or was spining the rear wheels and hit dry pavement more than once or B) backed to far into the water launching your boat and water came in thru the vent tubes of the rear end housing (see owner manuel),the water would have to come over the rear wheel hubs.

Now the 5.3's (flex fuel) engine has issues,starts with oil consumption,have you noticed your truck burning oil?,the valves and lifters or cam are a short term fix but these issues usually start to happen around 60K on problem engines,get the work done and keep an eye on your oil level,report oil consumption even if its down 1/2 quart,make sure your shop documents it and get copies,further issues I can fill you in on whats next.

Knowone will admitt it from GM but even tho I'm not a wrench some of my guys agree the issue lies because of the active fuel management,engaging and disengaging,would make sense since GM had similar issues years ago with the cadilac northstar engine,only the engine would jump from 4cyc,then 6cyc from 8cyc,cycle back and forth all day long,burned oil like crazy...So far we have not seen the oil issues in 2009 thru 2011~

"The traction control system may activate on dry or rough roads while accelerating while turning or abrupt upshifts or down shifts of the transmission,when this happens a reduction in acceleration may occure,or a noise or vibration may be heard,this is normal."

Just a thought~

GM uses the Eaton G80 locker (Detroit Locker) in their vehicles.  This is actually common with the G80 while backing.  The G80 is mechanical.  They clunk and at times are difficult to drive.
