1995 Ford Bronco - This write up is for changing the rear main oil seal. As you can see mine was leaking, not all that bad, but I had the time. This is not a… 1995 Ford Bronco - This is from sitting about 2 days, maybe a little bit less. 1995 Ford Bronco - The first thing you have to do is drain all the tranny fluid. I would say you don’t HAVE to do this, but I was changing mine any way. If yo… 1995 Ford Bronco - This is what the inside of the pan should look like, if you have big particles or pieces get your check book ready. 1995 Ford Bronco - Make sure you take the magnet out and clean it before you put the pan back on, mine wasn’t too dirty since I change the fluid once a year. 1995 Ford Bronco - The black thing with the spout is the filter it just pulls off. Be ready for more fluid to come out there is about a quart behind it. 1995 Ford Bronco - This is one of those parts I always get from Ford. (The tranny filter that is) I also use Royal Purple synthetic tranny fluid; it’s pricy b… 1995 Ford Bronco - This is what is looks like with out the filter, now all you need do is put it back on and bolt up the pan. 1995 Ford Bronco - Now that she’s empty with the pan back on you can drain the torque converter. 1995 Ford Bronco - Take off the little plastic cover and rotate the engine until the drain screw is right here. I just stick a big socket on the main pulley o… 1995 Ford Bronco - It holds about 4 quarts and it takes a long time for all of it to drain, so have a beer. 1995 Ford Bronco - With all the fluid out its time to start disconnecting things, like both of the tranny cooler lines. Make sure you only turn the little fit… 1995 Ford Bronco - They are both on the passenger side this is the one towards the front close to the exhaust. 1995 Ford Bronco - Now unbolt the starter, you can just set it on the exhaust or something, just as long as it doesn’t hang by the wires. 1995 Ford Bronco - Now just gently pull the kick down rod off the linkage, no need to un-bolt anything. 1995 Ford Bronco - You can just let it hang 1995 Ford Bronco - Next disconnect the front drive shaft. Make sure to be careful with the bearing caps if you are reusing the U-joints, I wasn’t so I didn’t… 1995 Ford Bronco - If your bronco suffers from the notorious “thunk” this is a good time to lube your shaft, if there is a bad time for that?!? 1995 Ford Bronco - Next peel back your carpet, if you have it to get access to the tranny access panel. Yours prolly wont have the wiring mess mine does, whic… 1995 Ford Bronco - By taking the cover off you get access to these 2 bolts which hold the tranny to the engine. I guess you don’t have to take the cover off,… 1995 Ford Bronco - Make sure you disconnect this wiring harness on the transfer case, there are 2 other plugs on the tranny, which you can take off if you wan… 1995 Ford Bronco - At this point I was taking the tranny out for the first time using a method I DO NOT recommend, I will show it to you guys just for learnin… 1995 Ford Bronco - A mechanic friend of mine suggested I simply by longer bolts and use them to slide the tranny back instead of removing it, so I tried it. A… 1995 Ford Bronco - Now it wasn’t easy to pull the tranny this far back, I ended up using a ratcheting strap, it was a big ordeal. But now you have access to t… 1995 Ford Bronco - Take all the bolts out accept one and then loosen it slowly until it comes off, make sure you have a good hold on the fly wheel before the… 1995 Ford Bronco - Make sure you mark it so you know which way it goes back in, you can see the black marks I made on mine in relation to the ground, you can… 1995 Ford Bronco - This is what your torque converter looks like, if you wondered. 1995 Ford Bronco - OK, now you have the rear main in sight, this is where things turned for the worst. I tried to pry if off with a screw driver, couldn’t get… 1995 Ford Bronco - At this point I knew I needed to remove the tranny. All my friends are loosers and refused to help me so I bought this $200.00 friend, it e… 1995 Ford Bronco - Ok, so now with the tranny out of the way I pried the rear main out with a screw driver easily. Be careful to not hit the crank (even thoug… 1995 Ford Bronco - I tried to get a pic of the scratch but the angle and such made it impossible. At this point I called another mechanic friend and asked him… 1995 Ford Bronco - So I bought this cost me $50.00 I about crapped my pants because it’s basically a little piece of stainless. (got it at NAPA) 1995 Ford Bronco - It comes with a little cup thing and you place it over the sleeve and the crank and hammer it on. The cup fits on that little lip of the sl… 1995 Ford Bronco - Be VERY careful cause one slip and repair sleeve is toast, and I don’t even want to think about taking it off. You should also put a small… 1995 Ford Bronco - OK, so now the Teflon sleeve……It said in the directions “not recommended for use with repair sleeve” I called both mechanics this time and… 1995 Ford Bronco - Now I smacked it pretty darn hard to get it on. I used the old seal turned around so I could smack it with a hammer. At this point I though… 1995 Ford Bronco - Finally got it on and got all excited to put everything back together. Tanny installation is the same as removal. It takes some time to get… 1995 Ford Bronco - Now for a seal comparison. This is the old seal, nasty and leaky. 1995 Ford Bronco - These are both new seals from NAPA (I discovered the NAPA Teflon and the Felpro one from advance are the same damn seal accept the NAPA one… 1995 Ford Bronco - Upon a closer examination I found the rubber one is tensioned to the crank by a spring because the rubber is very pliable, good for repair… 1995 Ford Bronco - So I did it all over again and put the rubber one on. Went on much easier. After I put it all back together after this go-round, I started…
