My rear diff sounds like my knees

Snap, crackle, pop.

My 2005 F250 rear diff pops pretty consistent when making a hard turn left or right. It has done this before, but not consistently.

Any recommendations? Truck has 100k miles.

Thanks

Did you just recently change the lube? Got enough limited slip additive? Mines ready for a new set of clutches, but it also did that when the lube got hot due to not enough additive.

Mines been doing it for almost 2 years now. Only does it when the diff gets warm. I have changed the fliud twice and added 2 bottles of additive the first time, still did it after 6 months so I changed it again and added one bottle of additive and one bottle of Lucas, same thing. But for me it only does it about 2-3 times a year the rest of the time I dont travel long enough to get the diff hot. Im thinking of a new limited slip, just havnt pulled the trigger
