differential housing temps

[2broke2gofast]

I recently picked my car up from the tuner and made the trip home on the interstate which was about 60 miles. When I got home I was started doing some exhaust work and noticed that my differential housing was very hot. I didn't notice any noise on the ride home, but was wondering if the temps should get the the point the housing is too hot to hold onto. Any advice would be appreciated. Thanks

they get hot. friction creates heat.

Maybe time to do an oil change.
