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...

I have replaced the outside axle seals more than once. I have it down to a 1/2 day job.. It seems that there's a fine line to how much fluid goes into the differential. On the GM 1500s you just cannot overfill it but, measurement is an acquired skill. Most of the youtube repair videos say fill it till it runs out. Do that and tow and it will start leaking. I stay closer to what GM recommends and so far, so good.
I installed the unitized seals from Torque King 4X4. I also bought the seal driver tool.
I haven't towed yet, but we'll see if I kicked the problem this time. I used 4 quarts of gear oil and that put the level right at 1/4" below the fill hole. Between the better seals and proper fill level this hopefully be the last time I have to tear into these things.
