Rear diff sealing question
I went to ford today to pick up rear diff fluid, im changing out my rear diff cover for an aluminum one and fluids have 83000 on them. So he says when you put the rtv sealing on, you let it skin over then bolt it on and let it dry for 24 hours before putting fluid in it because the synthetic oil will eat through the rtv if you add it to soon. Thoughts? I read most guys were only doing a couple hours and then putting fluid in. This was one of their mechanics that I was talking to..And when adding the fm to the fluid should I start with a full bottle?4oz. And add more if needed..Thats what he recommended.

what i do is: tonight i would drain and clean the surfaces real good and then put the rtv on the cover and let sit for 15 minutes. then bolt the plate up to the rear diff and be done for the night. go out in the morning and fill her up. when i add the fm i just dump the whole tube in and then fill with diff fluid but i get the tube from autozone so i dont know how much is in the ford fm tube. i have had trouble in the past getting my f350 diff to seal up but when i waited to put in the fluid until atleast 12 or so hours later its been all good.....

I wished I would have waited atleast 12 hours to refill. instead of 1 hour, because now I see oil seeping along the bottom edge.

First, make sure the fluid you have doesn't have the FM in it already. Mine did. If it doesn't, add 2oz. and test drive by making sharp left & right turns. If you hear chattering, add the last 2oz. You can add it through the VSS sensor on the top of the diff if you don't have enough room to add it through the regular fill hole.

To be on the safe side ill to the removing of the plate and fluids and resealing the evening before and refilling the next day just because I would hate to have to replace 80 bucks in fluids again. I dont use my truck when im sleeping so drying overnight is no big deal. Lol. Well sometimes when I dream I do!! Lol
