Rear End Whine
My dad's 02 suburban is makin some rear end bearing whine. It does it worst when the driveline is loaded. When you unload the rear, it still whines but is much quieter. If I remember correctly if you hear whine under load it means the pinion bearing is the culprit. Is this correct? Any other ideas out there?

If so maybe the lash between the gears was inproperly set.

How many miles on it to date?

Has he ever had the fluid in the rear end changed? If not, its definitely overdue. I'd start there first. Its a fairly cheap fix, if thats all it is. I just did mine this past weekend, took me about 30-45 minutes and about 25 bucks for the fluid.

I used dino oil when I did my eaton install and have had zero problems.
Don't for get the friction modifier!! 4oz bottle.
