Toyota Tundra vs. Chevrolet Silverado - READ ONLY

I have a 2000 sierra 4x4, 4.8 engine with 3.73, short bed. I traded in a 1989 f-150 short bed 5.0 4x4 with 100,000 miles on it. Needless to say, the ford did not vibrate, the engine did not run rough, The transmission, didn't make noises, the ride was positive not jumpy. If I wanted a truck to do all these things, I would have disconnected a sparkplug wire, blew out the shocks, and loosen a few lug nuts and i would have saved $24,000. I wish I had my 11 year old ford back.

I own a 1999 Silverado 5.3l engine. I have notice since the engine has 5000 miles that the engine knocks. I am a mechanical engineer and have owned 350's previously and have never heard such a noise. The noise sounds like low end noise and after reading your posted article I am convinced that I hear the main bearings knock for 5-10 seconds daily. and I cringe For 2001, the main bearing tolerances of these engines have been tightened for quieter, cold-engine startup. What the hell are these guys doing I pay 25k for a vehicle and now they are changing the tolerance of the bearings. Isn't it common sense that using a tighter tolerance will enhance a components life. What if anything are they saying about the 1999 5300 engines? Is general motors doing anything? Any comments will be appreciated. Thanks
