Hi all, i'm new to this forum.

I just bought a 5.9 last month, love it, but notice a whinning coming from front end. Seems to happen when I am on the interstate and let off the accelerator. Anyone have any advice and/or experience with this?

thanks!

I would check the front differential. Do you know how long ago it was serviced. The K&N thing doesn't whine near as much as suggested.
