Replacing upper and lower ball joints plus axle seals because they're worn and leaking. I have everything torn down

Q1 : what kind of grease do you use for the wheel speed sensors? I pulled them from the hub and feel like they should be cleaned.

Q2 : my diff fluid (85-140) turned into silver paint. I'm running 31"s and this keeps happening. I'm not mudding or riding too hard. Wth?

 

Silver paint - Bad sign, can't make it grow back with snake oil. While diffs can be rebuilt, you might also find some at the big boneyards near you.

 

Also how hard do you have to pound on the steering knuckle to get it to drop?

 

I replaced the rear diff 10 months ago and it happened again?

 

Ok I have a splitter on here, took a blow torch to it and I'm pounding it with a sledge. I don't get it.
