Rear differential covers
I’m getting ready to have the rear diff serviced and am considering adding an aluminum cover with heat sink. Have you gone this route? Does it make any significant difference? I have 155,000 miles...

Again, amazon sells the factory ford finned cover for approx $45.
Ford guys must be really lucky. Amazon has the 11.5" AAM finned cover for $227. The Ebay price of $190 with shipping included seems to be the lower option out there.
I've had leakage issues with my outer hubs and have some planned work soon. I'm going to be replaced outer hub bearings and installing unitized hub seals so I thought I might as well get this finned cover and install that while I'm at it.
I'm not sure if my seal leaking issue is related to poor seals, sealing surface, heat, or blocked vent tube. I'll certainly look into all of those, but the decreased temps created by the finned cover will certainly be a nice bonus.
