I have a 99 Silverado LS 5.3 new body style. I noticed a loud knocking noise coming from underneath the truck when I let off the gas. I thought it was the front drive shaft u joint but I took the drive shaft off and drove it and it still has the knocking noise. Changed cv axles both sides. Put new seals on the front diff. Brand new suspension. New control arms. And still can’t figure out what it is. Any guesses?!?!?!
I know there is extensive topic on this bit my question is a little different. I have all the the symptoms I have read about in other forums but I do NOT have any Check engine lights, transmission lights, or codes. My dealership said there is nothing nothing they can do and GM will not do anything unless it has had any of the above. Anyone else run run into this ?
