Thanks for the video. I just changed the seal on my 2011 Chevy Silverado 4.3l. For those of you who haven't done this before, don't let the size/length of the drive shaft intimidate you. Mine was aluminum and not heavy at all. Furthermore, I decided to leave the driveshaft elevated. I placed a milk crate with some 2x6's just forward of the differential and added a 2x4 between the mid cross-member and drive shaft. This means you simply disengage the drive shaft and shift it out of the way enough to access the seal. I think this was much easier than dropping it all the way down and and lifting it up back into place. Simply use whatever you have in your garage to keep it elevated near the same level and carefully shift it to the side.
@margaretjohnson7910 Thanks for the adding your helpful information for viewers. Thanks for watching the video & adding your experience. Keep wrenching! Kenny
Good video, my only recommendation is replace the bushing & yoke also. As you could see the seal was already replaced, it went bad again because of a bad bushing/yoke/u joint, which cause vibrations.
I just did this on my Astro. The seal was original and tight against the transmission housing. To remove the seal, I used a good brand new chisel and hammer to VERY carefully to go around the seal flange and separate it without damaging the transmission. After that I hit the flange with a screw driver to deform it slightly at one point in the old seal for removal. Worked perfectly and in a couple minutes it came right out. No damage or marks on transmission housing. For installation of the new seal, one of the cups in my ball joint press fits perfectly over the new seal.
I have a 2001 GMC 1500. Had the output shaft seal replaced. It is still leaking where the tailshaft and the seal meet. Not leaking from the rubber boot. I noticed that in the video you put grease on the inside of the seal and sealant on the outside. My mechanic did not put any sealant. Would that cause the leak? It is only a tiny drop. What kind of grease did you use? Trying to find your seal prep video. Thanks.
dont know if youll see this or not but i was wondering if there is an underlying issue because my rear diff is leaking a bit too and so is my tailshaft thanks in advance!
If the seals are constantly going bad, the tailshaft seal could be caused by either excess play from a worn tailshaft bushing or rust build up on the shafts yoke. Possibly even a worn yoke. The pinion seal in the rear axle could be from too little preload on the bearings or similarly , a rust or crud build up in the yoke that rides in the seal. I've on a rare occasion seen the yoke actually get a wear groove from the seal. Thanks for watching
Send a photo to the Facebook page Wrenching with Kenny with a description of the information you're looking for. I will have Kenny look at the page tonight. Thanks - Meg aka Mrs Wrenching
What tool? The seal puller? If he doesn't use one, and doesn't like to use one, why the hell would he show it's use? He's showing you how HE does it. You wanna know how to use the puller, check the top of the RUclips page. There's a search bar there. Type in "how to use a tailshaft seal puller". Genius.

Looked kinda like the rear differential had some leakage too. I was thinking one of the U-Joints might be bad or may have been at some point.
Definitely made me feel confident about trying this myself
Great video Kenny, just what I needed to "brush up" on replacing the seal in my 2003 Sierra! Subbed, liked and shared!
Man, I don’t know if I could have ignored how bad those u-joints looked. But overall great video on how to replace driveshaft seal.

Thank You Sir, Your video & wisdom is very knowledgeable!
You are most welcome. Keep wrenching 🔧
boss man you make it seem so easy i hope this will work fot my 94 impala SS
It will. You've got this. Let me know how your repair goes. Keep wrenching 🔧
Thank you so much I’m gonna do this in the weekend so Helpful 🙌🙌🙌🙌🙌
Good video without being overly wordy. Thank you.
Thanks boss a Gare fix my truck tomorrow 👍👍👍

If the OG seals were not packed with grease then why pack the new one with grease?🤔
What did you pack the seal with sir?
I have seen the tail shaft it self let fluid leak out yoke some have a air hole for when you push them in it let’s air out
The rust pattern on the yoke can cause them not to fit correctly in other positions
Great video
What about the leaking pinion seal ?
Keep them coming
Looks so easy...when you do it.
Lol . Thanks !! Been doing this for years !! Thanks for watching !!

Thank you for that video.
Thank you Sr👍🏼
What did you pack inside the seal?
Transmission assembly gel. Any auto parts store or Amazon has it. Keep wrenching 🔧
How much would you typically charge for this kind of job?
what’s the part number?
What would be the cost of that seal replacement, you know from fair to high? TIA
I have a 92’ with a 91’ manual getrig HM290 transmission. Is it the same process?

Was the trans already empty?
What is the blue stuff? You packed the seal with. Thank you!
Transmission assembly gel. Thanks for watching 🔧
@@WrenchingWithKennyYou’re welcome.
Which seal did you use? And where did you get it?
For future comment readers. Auto parts stores. Year, make and model specific.
I’d go with the brand National or Federal Mogul…
How much would you expect to pay at a local garage to do this job?
$80-$130 an hour.
What grease did he use ?
Transmission assembly gel
I need some help I have a 79 c10 and the tail shaft has play in it I think that’s ruining the seals. Is that play normal
The shaft goes in about 1 inch then we feel resistence. Very strange. Seems to go in like that in 3-4 different locations on the driveshaft
Ahh yes, dont show the tool or how to use it. Thanks genius

Right? I sat through this video to see the install tool and how to use it. He showed EVERYTHING but that.
What grease did you use to pack the new seal?
