A RTV silicone gasket maker or a bought differential gasket? ?
I've got a leak, and I am going to just go ahead and replace the pinion seal and rear differential gasket in my 2003 F-250 Super Duty Diesel.
For the diff I've been told a million different ways to go about it, and at this point I don't know which is best.
Some have told me to use a RTV silicone gasket maker
Some say to just use a bought diff gasket that is the right size
My dad told me to use both and put the RTV on top of the bought diff gasket.
Any recommendations?

Please remember that there is NO PRESSURE in the Dif Housing. So sealing is easy. I use Hi-Tac to glue the gasket to the housing and use just the slightest skim coat of RTV on the cover. But you can glue it with RTV too, use a medium coat for that. Put the bolts in finger tight and walk away. Come back an hour later and snug it up, around 20/25 ft/lbs is the usual torque. Look up yours. Try to get a fiber gasket not a cork one.

Put a gasket. Install and torque the bolts according to the service manual. Check for leaks.
