  • Thanks sir!!

  • You got it!

  • Great video, i think i know why my pinion seal busted, ive been mudding, off roading, and am thinking that possibly that air hose is blocked. I guess ill find out!!

  • Great video, very educational. Now I'm ready to tackle this problem.

  • Thanks, guy! We try!

  • Man this was good you guys should be making videos and selling them to make $ off this

  • That's Why the SAE cert is there. This Guy is awsome and well, a good Teacher. I wish I would have learned this way. I had to learn everything from the Ground up and still going to School. My Main ideal is Honesty. Great Shop. Mechanics get a Bad rapp enough said. Cool Vid

  • Well, you're right - sort of - but it has been years and the nut is still tight. I inspect that car once a month :)

  • No new nut! Tut tut!!.at least use thread lock lol.

  • Wow, thanks for the comment... LOL. It's explosive.

  • Thank you for a very informative video... especially ... 1. verifying the #turns when removing and replacing the pinion nut and #2.... checking the vent...

    THANK YOU ..... GREAT WORK!!!!!!!

  • Great Video Guys!!! Thanks for the Vent info. I think I'll do mine now. Wish me luck

  • im a.s.e certified. i had fun in auto tech school :)

  • Thanks for good video and narration!

  • good

    thank's

  • Great video.Just wish I would have watched it before I improperly preloaded my bearings after changing my seal.Costly mistake and lots of work to fix.Almost have her done now.

  • This is a good video, great information.

  • Very goood video!!!!!!!

  • Yes, you can replace just the spider and axle gears - they're available separately and are quite simple to change. Just make sure you flush all metal particles out of the differential.

  • @McCuistian i changed the differential seal in my 94 toyota previa, but it is still leaking and i don't know why?

    so if u could help me out with it that would be awesome. thanks

  • U shuld make a video of rebuilding a differential.

  • @kodye414 come on dude for christ sake that would be epic failure!

  • This is one hell of a video. I learned alot. Great Job.

  • great vid. too bad i didnt watch this before i pulled my pinion nut off without marking it :)

  • No. That's what counting the turns is all about...

  • i thought u hve to replace the crush sleeve whenever u release the pre load pressure on it.

  • Nobody can say for sure how much a shop would charge except for the shop.

    Secondly, the popping noise is something you'll have to find - loose parts don't always show up to the naked eye. Bite the bullet and take it to a shop.

  • What do I do if I'm leaking differential fluid out of the back of the drum where the axle connects to it, on the rear passenger side of my 93 ford f250. I have no shop grade jack and stands. How much would this cost at a shop plus my truck pops underneath when im in reverse and give it gas. Would this be the u joint, or the suspension bushings???? ANYONE????????

  • You have to remove the seal, bearing, and the sleeve (which can either come out easily or be kind of stubborn). You're really supposed to replace the nut as well, and torque it in small increments until the pre-load on the bearings is right (measured with a beam type inch pound torque wrench based on the amount of torque to keep the pinion turning after you've started the rotation of it.)

  • Outstanding video, I'm waiting for more.

    How much extra effort is it to replace the crush sleeve and torque the crush sleeve to specs again? By the way, does the front diff on these axles have a vent tube as well? Thanks again for your effort -- I know how much work this can be.

  • Thanks for that video. I noticed my pinion seal was leaking a few weeks ago when I was changing the clutch on my Jeep. Now I know how to properly change it.

  • nice video.. Just installing a used rear end in a friends truck tomorrow, and noticed this seal was leaking.. I planned on just impacting it off, but now I know how to properly do it!

  • Thanks... I just wish I had time to make more videos...it's a labor intensive process to make a good one.

  • @McCuistian Thanks for the video.seems like u are professional mechanic. Just need some answer, my car having problem with the rear axle shaft. Only one side of the drive running. We found out that the gear inside the differential worn off after more than 10 years never change. Any possibility that we only need to change the worn gear without change the whole sets including the shaft?My concern on different materials and types can affect the performance. Looking forward from your reply soon.

  • This is a real world approach to pinion seal replacement nice vid, I thought when you asked the kid to paint a mark he was going to paint the whole rear-end white haha, nice catch on the vent thats what seperates mechanics from parts changers. Keep up the good work.

  • Only rear wheel drive cars...

  • nice video, what vehicle is this? does this apply to every rear end?

  • Great video < Thanks

  • very good well done

  • Thanks!!

  • DO MORE "HOW TO" videos, the rear end is a monster by it self, this was very informative.

  • Good stuff guys. Kudos to both of you.

    Working on replacing blown jeep ring and pinion but found this helpful even in my spot.

    Thanks!!

  • "You know better than that, We could knew better than that"... lol

  • The torque is not as important as not OVER torquing it and distorting the crush sleeve. That's the point.

  • McCuistian: Thank you for sharing this video. I saw that you did not get a new pinion nut or driveshaft screws. The Ford workshop manual and Haynes recommends doing this without the parking brake and by removing the wheels and calipers and using a torque wrench and a special tool. How can you be sure that you are getting the right torque by counting the turns on the nut? What about any possible stretch or fatigue on the pinion shaft or nut? Should this be accounted for?

  • Thanks for posting this. I have to do something similar on my Impreza, and was intimidated until now =)

  • Great video! Very informative and wow, I really will do this to mine now. I got a 1986 Chevy Astro. Keeps leaking, gonna change my seal...maybe just check to see if that breather hose is clogged.

    Thanks a lot!

  • Not sure how you can do that when the seal is destroyed during removal.

  • What I wished this video showed was how exactly the seal is damaged from pressure. Also, it would have been helpful to mention to look for damage on the pinion flange or people will be repeating seal replacement. Thanks for the vids. Your a swell guy for doing so.

  • Great video. I have a 2005 dodge 1500 4x4 and the pinion seal is leaking, its all over the spare tire etc...I was wandering why it would blow like that. that part about the pressure gives me an idea why mine may have blown, since it stays on the road, city and hwy driving only. thanks again for the video .

  • @01po01po the vent hole is likely clogged

  • that was a real handy video you posted there, i have to do that on my 1993 toyota hilux next couple of days, wouldnt have done it without it, thanks guys

  • great video. thank you guys.

  • Side of the differential there is a 1/2 inch pipe plug (it's bigger than 1/2 inch by the way) and you take it out. Pump or squirt rear end oil in there until it comes to the base of the hole.

  • Did you replace any lost gear oil? If so, where do you fill it?

  • Checking the pre-load with a torque wrench isn't a bad idea, but if you take pains to put the nut back where it was you'll do just fine - the car we did that work on is a state vehicle that has gone many thousands of miles since we did the work with no more leaks and no issues. When rebuilding a rear end from scratch, you really need to check the pre-load with a torque wrench (because you're supposed to have replaced the crush washer and you're crushing it for the first time).

  • I've read some literature stating that I should measure the bearing pre-load torque with a torque wrench. Is that a good idea? If I do exactly what you do (use the paint pen to mark everything and count turns), should I come out with the exact same results?

  • Good video; answered some questions I had. I wish you guys made one of changing out the bearings.

  • You do apply the parking brake after removing the driveshaft so the pinion shaft won't move.

  • Im sorry one more question, do you apply the parking brakes during this procedure?

  • I am going to attempt to replace this pinion seal on my jeep wrangler , I got confused when seeing others just yanking the drive shaft out and having to mark with soap stone, but watching this looks like I can just let it hang out of the way and mimic this?

  • Also here's my actual differential video just thought seeing is more than words

  • This video is pretty cool being I have to do this exact same thing , I have some pin play in my differential and am thinking it has to be my axle bearings, if you wouldnt mind could you listen to my video and tell me if sounds normal or bad?

    My diff looks good from all moving parts in the rear, but that pin between the spider gears moves to much I believe. Had a mechanic quote 1800 and up for fixing but I cant accept that except these axle bearings n pinion seal. Thanks much for any imput.

  • Great video. I am in an auto tech program and this cleared up a lot. Actually seeing repairs being done makes it easier to understand other aspects of the differential.

  • wished i saw this earlier. it would've save me a trip back to the dealership today for a second new seal! good video. now i know better. thanks.

  • You're funny. We don't have an accent here in the south - now those guys from Massachusetts and New York, now those are annoying! (not really... I love those guys).

  • what an annoying accent these guys have but the vid was very good and instructional others dont teach just tease good work

  • Thanks for the excellent vid!!!!

  • great video amigo

  • Excellent video. My Dodge Ram needs new seals on both differentials. This helps a lot! Mucho gracias!

  • Great video guys!

  • positively the best video i have seen on this. i need to do this on my jeep, now i can do it no problem! thanks for posting this very informative video! 5 stars.

  • them damn dana 35s, i gotta do the same thing to mine lol

  • thats all good but the Crash-Bearing is like a lock washer an thats not got no more preload on it .

  • It is designed to crush, not crash, and it's a sleeve, not a bearing.

  • Very nice, you can put a fule filetr on that hose, purolator F20011

  • Thank you ..it was a great help

  • I did it last Sunday, thanks to your video, and you for talking the time to post it.

  • Great video. Rebuilt my first rear diff. over the course of the past 3 days, that crush sleeve is a pain!
