How to seal the Ford 9" third member (with no leaks!?)

Hey all,
I have an elementary question.

How the devil do I get my 9" ford to stop leaking around the flange and possibly the studs. Hard to tell exactly where it's coming from.

Do you guys use the gasket? RTV? How important are those little washers? Mine where tore up so I didn't reinstall. Is that the problem.

Sure appreciate any info on what works!!

THanks. jer.

I've always used the RTV black or blue - no gasket. I think the copper washers provide some seal against the rough texture of the case. You can tap them flat again or find some at Lowes or home Depot maybe.

how to seal a ford 9"

I use a new gasket and new copper washers (most real parts stores stock them,I beleive) . If you are using synthetic gear oil you may still have some seepage,that stuff will seep through anything.

The key is the new copper washers for the bolts. You are better off using no sealer or gasket gunk. Use a new gasket and clean both surfaces completely. Re-assemble with new washers and do not over tighten.

Hey thanks for the info!

I have heard both sides before, but I think the gasket with new washers probably is the best. I guess the washers must be copper so they can crush down a little.

That is correct, they actually crush down around the threads of the studs and seal them against the third member case. I have seen aluminum washers to from the factory used on Ford 9 inchers. Also I have seen regular hard metal washers used (non factory) and the subsequent leaks they cause.

thin layer of ultra black on both sides of the gasket, let set up for about 15 min, copper crush washers(from Ford). Sorry, do not reuse old ones. Set pumpkin, torque to spec, check in about 100 mi or so, re-torque if needed. If you have problems, make sure the vent fitting is not clogged.
just my .02, but it works for me
