Yes, completely normal. That is surface hardening done at the factory. It is NOT overheating or damage.Folks; seen a birfield looking like this before? right side axle seal been making a mess, just dismantled to replace. what's thoughts on returning to service?View attachment 2491194
If it's tight enough to hold position, you're good as long as you see no chips or nicks on the balls, cages, or pockets.Breathing life into an old thread. Mine too shows this blueing. The balls and the cage does not show any chips, scratches, or corrosion.
HOWEVER, it sort-of sticks every now and then when I rotate it and will hold (not drop) every now and then. I cleaned all the grease out of it and brakleen is coming out clean(ish). Should I just grease it and send it?
How much wiggle / movement in the birfield is normal?

Many of us use Valvoline Palladium.All I could find locally was MasterPro Moly from OReilly. Doesnt say what percentage Molybdenum. Anybody know?
Here's a pic of the wear on one side of the cups. Like you said, swapping will help to get more mileage. @GerhardUngerer needs to dissassemble birfs to see and do this, IMHO, and also accurately evaluate situation.As above, tight is good, it's likely sticking just because everything is dry, lubrication is needed. If concerned take the CV joint apart and inspect.
IME you're better off taking the axle shaft out of the CV joints (Birfs); that will allow you to fully clean and inspect the guts of the CV joint and completely repack the CV joints before stuffing the axle shafts back in.
But also with the CV joints separated you can then swap the birfs to the opposite side axle shafts. When you do that the CV joints will then be running in what used to be their reverse direction. IME that can help get more mileage out of a set of birfs particularly because the left side CV joint tends to wear a bit quicker than the right side.
Use the highest % Moly fortified grease you can find, 5% is ideal, 3% is minimum, IMHO. Valvoline Palladium comes in both 3% and 5% but the 5% is harder to find (try Summit Racing or NAPA stores in the US for either).
There are other greases of course (Mobil, Shell, Chevron, Pennrite in Oz, ---) depending on where you live.
Personally I use Amsoil moly for everything on the truck. I stopped stocking different greases years ago.The first pic is for the knuckle bearings right? Not wheel bearings? Those use red bearing grease?

Both greases are "chassis" grease, as specified in the FSM.The first pic is for the knuckle bearings right? Not wheel bearings? Those use red bearing grease?
