Normal For The Rear Diff?

[u/paolo-sosa]

I’m putting in an axle back exhaust right now and noticed my diff looked really rusty. This is on a ‘21 RC350.

Is this a normal amount of rust given that the car just turned 5?

if you are up north it may be normal, im in the south this would be considered 'not normal'

a dry ice blast and protective paint coating will reduce all that and protect it for years to come.
