Strange 'Gear' Whine

[88-GT]

About a year ago now (4-5000km) I did a complete rebuild on the 8.8 in my mustang. This included gears, trak loc rebuild, and all the bearings and races including axle bearings.

Lately I have been noticing some whining comming from the diff. It is strange though in that it only occurs while turning right at any speed above say 25km/h.

It is faily loud and is begining to bother me, still something that can be drowned out by music but I want to fix the problem. Any ideas on places to start, or probable cause? Thnx in advance for any help.

could it be a front wheel bearing....perhaps a LF wheel bearing

Were your side gears and spider gears pitted when you rebuilt the diff? I have seen alot of pitted gears and they only make slight noise when turning.

I ran my diff low on oil and it now whines like a b%$ch. I guess the bearings probably are ruined
