    The previous two posters must be smarter than I. The only time I went RTV only on a diff gasket, I had problems. I always use RTV/gasket to keep the thing sealed.

    What do you mean by "is it hard to get off." Do you mean the gasket or differential cover? And I use the gasket and a ton of rtv. Never leaks. /forums/images/graemlins/thumb.gif

    I just do a single thin, about 1/8" diameter, bead on the diff housing itself, stick the cover on and bolt it down, never had a leak yet /forums/images/graemlins/thumb.gif.

    Comes right off with a putty knife to /forums/images/graemlins/thumb.gif

    i use rtv personally... i think if u have any kind of damage to the cover or housing (ie not full on breakage, just rough spots, slight bending etc) then rtv seals better than a regular gasket. It gets in all the nooks and crannies, while a reg gasket assumes its going between 2 perfectly flat parts.

    Silicon and a gasket for me.

    The rtv will fill in imperfections like the previous post states. I always smear (with my finger) a very light coat on both metal surfaces. This works very well. I just pulled the cover off my 12 bolt last weekend and the paper gasket delaminated perfectly. There is a 100% complete gasket on both the diff and the cover, just 1/2 as thin. There is no way this will ever leak. Also, don't over tighten the bolts if you use a gasket. It will crush the gasket and cause leaks. I torque em down to about 15 pounds and have never had a problem with leaks.

    Good luck

    I always use the gasket with the RTV on the cover, since the cover is easier to clean off than the housing, for the next time you pull the cover.

    Really should only *need* one or the other (RTV or gasket only) but it doesn't seem to hurt to go all RTV, or gasket/RTV. *Very* little RTV though...I spread it with my finger so that its thin enough to almost see through.
