    Question about 7.4l Oil Filter

    Just to follow-up on this post. I changed only the oil filter (to a new AC Delco PF454) and the leak went away.

    Had a similar issue - 99 K2500 Suburban (lifted on 35's). I was convinced it was the tires. One day I randomly decided to replace the crusty suspension shocks with some high quality Bosch shocks. The problem immediately went away. The old shocks had virtually no rebound - so the front end...
