Rear main seals always a pain, so time consuming no matter what motor it is on. Thanks for another great video

[glennfields]

I hope that I never have to do something like this procedure but I enjoyed watching it being done by a first class, master mechanic. Thank you Kenny! I appreciate you brother.

Great video as always.
7:10 there are repair kits for worn shafts, it’s called Speedi sleeve.
Just type it in here on Youtube and learn all about it.
It saved my wallet when I owned a Ford ranger with leaking crankshaft seal.
Keep wrenching, love your work.

YOU WANT TO AVOID DOING A REAR MAIN SEAL!?! I bought a Chevy 5.3 v8 suburban. When I got it whenever you would shut it off it would leave a small quarter size oil spot by the rear main seal. I did not want to do the labor and at that time I did not have a lift!! You know I’ve never believed in snake oil too much! Lol so I bought some Lucas stop leak. I was already using Lucas in the suburban anyways. I added Lucas stop leak for three or four oil changes that rear main seal sealed up and it never leaked again I pulled cars and plowed snow with that truck. I also drove it to 325, 000 miles never a leak on the ground again, great video Kenny! Also, if you’re driving an old vehicle, make sure you use some kind of oil with seal conditioner in it. My preference is Valvoline max life which I took the truck to 325, 000 miles worth the truck is still running and driving today! Good luck!

Another thing I use for transmission piston seals is cut the outer ring off a cool whip lid, run a lighter around the outer edge to remove any sharp edges. Then run it around the seal to push the lip in without hurting anything. Used to use a feeler gauge but after cutting a few seals, I tried this. Works great.

Great video!!! One important part of any seal replacement is lubricating the lips of the seal prior to installation. If the surfaces were cleaned with brake clean or another cleaner then the seal may be damaged since it will run dry.

When I kid, my father would always work on his own cars. We had a garage but you had to jack the car up and put it on blocks. When I was off from school my father would give me tasks to do to get the car ready for the work he was going to do the car. This time the bell housing seal was leaking on the transmission. So after all the work and finally getting the transmission out from under the car, my father put the new seal in. And of course like you say reverse procedure to put everything back. Come to find out he didn't get the seal right, somehow he distorted it. And we had to do it all over again!!

One way to check anything like this for burs is run a little ball of cotton around the groove where the seal goes

I just did a rear main seal in my wife’s 2017 dodge Journey. It was frustrating because it later became obvious that the Mitchell DIY instructions were meant for a different model in the 3.6l variety. Figuring that out was easy compared to sneaking the transmission back in.

The rear main seal was leaking on my 1998 Dodge B1500 Class B motorhome and I used some AT-205 seal stop leak and it quit leaking.
1, 000 miles later, I changed the oil and it was leaking again so, I put in the stop leak again and it stopped. Hopefully this will keep working as I am on the road full time for over a year now and do all my own work but this is a big job. Good news is, no need to remove trans. The 5.2 liter engine has a split rear seal that can be removed after dropping the oil pan but you have to remove a crossmember to get the pan out. Then you remove the rear crank bearing block, remove old seal, install new 2 piece seal. Watched several vids on how to do it. Still a big job for me to do out in the woods alone. Going to put it off as long as possible.

Thank You for another very informative video Kenny.
Much Love and Hugs

[craiggerber]

thanks for teaching us how to. your honesty and straight forward . Thank you.

[adanarvizu]

Thanks for the tutorial, FYI you can use the old seal to tap the new one in. Regards!

[lo-wr]

Make a run to home depot or lowes to get a seal installer, lol a man after my own heart. Old cobalt and I would have added AT205 to the oil and call it a day.

I remember when those pop corn aluminum heads came out, I'm not to sure designing blocks is a good idea, I'm really glad you're adding tools to your videos.

[markhuyette]

Thank you for the tips and have a blessed day today 🙏

I love being a mechanic, most of the time. It's a sense of a true accomplishment that only one would understand. The high one gets from that diagnosis and the completed repair is indescribably. Unless I'm working on my own vehicles, not only because of the inconvenience but because it's my money I'm watching add up the further I get in to it. But a mechanic replaces what's bad on the way to the main project at hand. Mechanics don't do what customers nearly always tell the mechanic, just do what what the car is in for, i.e no preventive maintenance.
But I think that's because a mechanic understands the work involved. It's great for business, that's for sure, because we can gamble when that vehicle will be back they actually can double the repair cost by skipping it..
But sadly many people hide their shame and take the vehicle elsewhere when those other parts break and blame the previous mechanic when they dam well know they were warned.
That's why I take what people say about a mechanic with a grain of salt. Unless it's a jiffy lube employee at most Walmart mechanics, but they aren't mechanics in my humble opinion, they are just highschool kids.
They say cops see the worst of the worst, and that may be true, but a mechanic has to be a close second seeing what conditions people will drive with. "Just replace the tie rod, and leave the bad wheel bearings and clunking ball joint(s) alone." Three weeks later they blame you for the wheel bearings or ball joints saying it's something you did installing the tie rod 😂. Of course they are just trying to get free parts and labor. Document everything!
God bless.
