Just recently a new noise began on my GMC
2500hd 6.6 duramaxx. Every time I get between 15
and 20 mph there is a whooping noise (seems to be
around the front wheels). It's a pulsating pattern
every second or so of whoop whoop whoop whoop.
Any thoughts on this? Thank you
Sounds like you should have the front wheel bearings inspected.
Check for flat spots on the tires. Check the wheel bearings.
