99 K1500 Suburban 5.7L GU6/G80 Rear
I swear, I fix one thing on this truck and two other things pop up.
Trucks been inop for the past 6 weeks while I worked on upgrading the injectors and replacing front end components (ball joints, tie rods, and idler arm).
Drove it today for the first time to have it aligned. About 3 miles into my ten mile drive, I started hearing a humming noise but only when I let off the gas. As long as I was accelerating or holding the speed steady, I didn’t hear anything. Sound seems to be isolated to the rear of the truck.
Truck just turned 308,000 miles. I’m guessing that I’m looking at rebuilding the rear diff.
Is there something else that anyone recommends I check?
Fluid was changed in September 2023. Old fluid was dirty but no metal pieces found.
I’m planning on popping the cover off this weekend to check the condition inside.
This is another “new” repair for me and I would really like to do it myself. Doesn’t anyone have any advice or suggestions? Any good instructions out there?
Thanks in advance for anything you can recommend.
