Facts: *There is a Growl/Grind coming from the front driver side as far as I can tell. *Noise is present during deceleration 30mph and under. *Noise can not be heard during acceleration. *Noise exists while coasting in neutral as well. *There are no visible leaks anywhere? *Noise is amplified while turning. *Noise goes away after shifting back into 2WD. *There seems to be no issues shifting into and out of 4WD Hi or Lo. *Tire wear is consistent and even. *Front inside brake pads are not engaging rotor on either front wheel. Actions: *Changed out front differential gear oil. Drained a purplish, thick oil w/ what looked like metal flakes/sparkles. Magnetic drain plug had a few small splinters. (<1/8") Refilled w/ Valvoline 80W90 Synthetic Gear Oil - Noise still there. *Local performance shop seems to think it might be a wheel/hub bearing assy. If a bearing, would the noise be consistent during accel and decel in 2WD or 4WD? So I have my doubts about this being the issue. Questions: *Does the front differential disengage during decel or is it engaged all the time in 4WD? *If it does disengage, what controls this? Front Axle Shift Motor? *What do I look for to tell if it is a CV Joint? *Any suggsestions or help is appreciated!!!

Replying to: dans04z71 (Dec 08, 2008 4:36 pm) The cost, $175 timing chain, 10 cluch disc apx $3.00 each, Anitrobic gaskit sealer $17.00, 3 quarts Gm Trans fluid $24, 3 shaft seal $15 apx ? can't remember the exact price. and 8 hrs labor, first time rebuilding the transfer case. One thing I have not check out, it appeared to me there was a adjusting screw for the cluch plates. Only two of the clutch plates were fried the other eight still looked good. The point being I think maybe I could have adjusted it and it would have been good for another 20-40k miles. I put apx 80-100 hrs a year on it plowing every year so it has held up good.

I was shopping for a new Silverado 1500. The dealer said he had a new 2007 Silverado 2500 which had been "lost "in his Inventory which had an MSRP of $30,000 that he would sell for $20,000. When I checked on Edmunds I found 2 other dealers with similar deals on the 2007 model. Does anyone know whats up.? Other then gas mileage do you think the the 2007 2500 is better than the new 2008-9 1500?
