I was looking at the rear end of my truck and noticed a lot of rust on the cover to the diferential. I did not appear to be a surface rust issue, the exterior laver had flaked off.

Anyone else have this issue?

I guess I'm off the the dealer.
I have 51,000 on it hope this is still covered.

 

Only rust from perforation will be covered.

Gat a can of rustolium paint and spray it. I do mine that way. Keeps it looking new.
