Posted February 9, 2011

i have a 2004 with the 8.1L. i removed the crankshaft pulley to replace the seal and noticed that it's not keyed. so now im trying to reinstall it and am not sure how it needs to go on. i noticed there are a couple holes along the outer ring of the pulley that appear to be there for balance, but im not sure. the end of the crank has a small beveled area at the very tip of it, but doesnt go any further back. i just dont want to put it on wrong if there is a way it needs to be aligned. any help would be greatly appreciated. thanks!

  At the first 420 miles my truck ate over 4 1/2 gallons of DEF. And it still guzzles it much faster than it should for normal non towing. It s on its third battery in under 4 years. It gets GM Field Tech approved fuel mileage of less than 70% of the EPA rating. I have hundreds of 100 score Chevy Smart Driver app, saying it is the most fuel efficient. After belonging to dozens of Facebook groups, and the massive engine, and transmission problems. Of Chevy/GM, Gasoline and Diesel, engines, on trucks and SUVS. Is the 2027 3.0 Duramax fixed to end these. Problems? I’m hoping buying a new 2027 will fix them. As this is my fourth Chevy I bought, the last three where new. GM ignored the Detroit MI BBB final repair I bought the Diesel to out last me. And I can’t afford buying three or four trucks, to make sure 1 is not in the shop! Thank you!
- Defective Brake Pad Wear Sensor?

  My 2020 Silverado 1500 LTZ Diesel has close to 100 fake, new brake pads sign on the dash board. Now it is says service the sensor, 1% wear left on it. IF CHEVYS HAVE A SERIOUS PROBLEM LIKE THIS. Why isn’t there a recall? Instead of members on this site calling the dealership, and being told without inspecting, you need new brake pads? The truck already went through almost $2,000 in brake pads, rotors, at around 40,000 mostly highway mileage. Mininimal brake usage!

  They’ll be a deal. Maybe the fifth level of the supreme leader. But a deal is going to happen.
