Ok, so my diff. has been slowly leaking for some time now. I've tried to fix it 3 times and it still leaks[:@][:@][:@][:@] My question is what am I doing wrong? I bought a new diff. cover and used the red high temp RTV. I made sure both surfaces were clean and dry and bolted it back one. I then waited 5 hrs for the RTV to bond and put the diff. fluid in. AND STILL IT F UCKING LEAKS!![:@][:@][:@] Someone help me....am I just retartded? LOL

 

never had a problem with mine ,,and i just use blk silicone too and put cover on right away and fill it up ....i just got a t/a cover i like it ..

I've never had trouble either. Do you torque the bolts to spec? I always try to torque when there is a spec and there is on the diff cover. I just use regular black silicone as well. I put the bolts in finger tight and let it sit for an hour or so, so that the silicone can firm up a bit. I do the final torque after that.

 

maybe you didnt put enought silicone around the bolt holes ,,or maybe the cover wasnt lined up with the holes when you installed it ,you may have slid it a bit ..maybe that what happened ..?? try agian..o that was you 3rd time ......get new cover

 

I did get a new cover cause I thought that might be the problem. I used a good amount of RTV....I made sure to cover the holes. The cover was lined up....uhhhh IDK[:@][]

 

i think you can get a gasket for them ..that might be what you need to do ...i know my stock cover was hard to get off ..i took off couple of times ,,,had to pry it off,,like it was bending ...

 

YEah, I had a gasket in there after I did the gears. But I called FORD to order a new cover and they said I didn't need a gasket....just some RTV. But I'm wondering if a new gasket would solve my problem.

 

worth a try .... i hope you saving the gear lube...?or you got the cleanest gears around...

 

LOL, I know. I actually have been using new gear oil every time[] I just feel weird re-using it.[&:]

 

maybe your not using enough silicone, or something is warped? do you have a vent up top of the housing that is plugged and it is creating pressure inside the housing when it heats up.
