Doing rear main seal....
Bought a rear main seal for the Bronco today, going to do it monday or tuesday. Any tips from members that have done it before? How many beer job is it?

Depends on whether you are pulling the engine or dropping the transmission. There is one little key to installing it easily. If you can find a thin plastic ring that slips over the crank rearend and then the seal slips over that it will go right in. Otherwise you need to find a large ring big enough to sit on the seal while you tap it in. Also lots of engine assembly lube and oil to make everything very slippery.

Its a one piece replacement, so ill just be droping the tranny. Cant wait to see all of the other things that will be begging for replacement. Like a flywheel with 3 teeth left....

hey matthewc do you have an auto trans or a manuel trans. if it is manuel you can just replace the ring gear on the flywheel.
make sure you pack the groove in the seal with grease or you will burn it up on the initial start up. otherwise you should have no problems. how many beers depends on what you drink. i usually wait till after the test ride but i guess 6 hour job 2 beers an hour you better get a case so your helper doesnt complain.

C6 3 speed auto. Good point about the grease, is there a specific type I should pick up? Maybe the beer intake should be spread out, I dont want to be crosseyed by the time I get the tranny back.

I use lots of assembly lube and engine oil from what I will fill the engine with. A high moly content grease would work too, wheel bearing or chassis lube, but I have a lot of the assembly lube around from building engines so I use it.

I did it on a different Ford, and it took me a almost half a day. The actual replacement was piece of cake, getting there, and putting everything back was the hard, and time consuming part. An occasional helper or two can come really handy. BTW, that car had a stick and by that time I was an expert on pulling the tranny and replacing the clutch....

Thanks guys, this will be an early morning start. So have a helper, lots of grease, and motor oil. This will be such a relief when it is done! Thanks you again for the help.

Great. Thanks alot for freaking me out some more. By the way, I read on an earlier post from someone else that had done this that they had simply slid the transmission back instead of dropping it entirely. Does anyone know anything about that?
One more thing, I hear all of you american posters love that product called Seafoam. Is there a Canadian equivalent? Ive looked all over town for it, but to no avail. Ive heard it works wonders.
Finally, ive heard that the transmission should always be tipped up, instead of nose down. Is this true, and also are there torque specifications for the flywheel when it is finally reassembled?

When you take the driveshaft out, there will be leakage unless you fit something in there, also when you take the torque converter off it will leak, alot if you tip it.
The flexplate is torqued 75-85 ft/lb. Use loctite red to make sure those don't come off.

Thanks for the responses. Ill see if I can borrow a digital camera to take some step by step pictures of the process seeing as this seems to be a common problem with Bronco owners, and im sure people would like to have a visual display of the repair to help them decide whether to do it themselves.

Use a big MacDonals cup like the supersized one to slide the seal over. Just cut the cup so it will just fit over the crank. Works great, I had four cups cut at different sizes when I worked for a Dodge dealer.
