As a retired mechanic after 55 years in the trade, I used to do it exactly the same way. What I would also do is to clean up the seal surface on the flange with very fine emery paper lubricated with methylated spirits ( white spirits). Far less likely hood of leakage again. I do this for all seal surfaces. That said, excellent video. Thank you Kenny

[@eddiereichel9354]

In almost every rear differential leaking issue I have come across the vent tube is plugged up.

[@harrystalick5260]

As below, also a retired mechanic of 55 years in UK. I would always check the axle breather for blockage after fixing an oil leak. Good job Kenny.

[@eddiereichel9354]

Sometimes just getting the vent unplugged fixes the issue. You can have a million years experience and not know everything. You would be surprised now many mechanics dont understand that suspension bushing bolts should be tightened at ride height. Heck Kenny here just posted the "funny looking valve cover video" There is a TSB about that issue. The PCV check valve goes bad and ruins the valve cover. Maybe he did it off camera but he never checked it. That is the root cause of the failure. When that check valve is ignored long enough the turbo is not long for life because its trying to pressurize the crankcase which its not designed to do.

[@eddiereichel9354]

I wouldn't be surprised if we have a follow up video of "axle seal leaking" since the pinion and cover are both new seals they are the next weakest link.

[@wonjat5]

You’ve done this job many times and it’s worked fine. Personal preference, clean off first, mark etc, but polish seal edge of flange, reinstall with a little bit of gear oil on the seal lip. I’ve never liked using an impact to tighten up rather feel if you’re getting too close to damaging the crush washer. Ouch! overdid this as an apprentice, a lesson well learnt.

[@haldooley4940]

Count the threads as well as marking just like you did

[@goodcitizen64]

That's the exact way my father taught me when I was about 12 years old! Many decades ago! Great video Kenny!!

[@ericknutson602]

Thanks for the great tip on marking the pinon Kenny. Taco bell with beer . 😅

[@petescustomcarshop]

I've never replace the crush sleeve when replacing the pinion seal. I can't say how many pinion seals I have replaced but I will say it's a lot. I set many 9" Ford gears for IMCA and USMTS Modifieds and I have hammered the old crush sleeves out so I could set the preload on new gear sets. Never had a failure. Thanks for sharing.

[@SeanBZA]

Best tip I can give to clean those oiled surfaces is a wooden outdoor broom, which you cut into small blocks, so you have 6 or so out of a single one. Hard bristles easily shift the dirt, and only a tiny amount of solvent needed.

[@bobby9195]

Good evening Mr Kenny, hope you had a great Tuesday and thank you for the video sir. Your information is very appreciated and helpful

[@stephenmeeks684]

Do you not need to check the dif vent as well?

[@glenndarragh4417]

Thanks for this vid Kenny, I've learned something today. I've always understood to retighten the pinion nut back to the original marked position. Interesting that you go slightly past this point, makes sense when I think about it.

[@MUSTANGGT12]

I do thank you for making longer videos!

[@betomendez4304]

Thx Kenny great video 📸

[@glenndarragh4417]

FWIW I like to check the diff breather while I'm there just in case it's blocked up with crud.

[@Jack-ns5mn]

On one job I ran in to an after market device that positively locked the pinion nut in any position with wedging action from allen screws. This would allow you to set any preload you wanted even if the crush sleeve was over compressed and would avoid any backing off when reusing the pinion nut. I've tried red lock tite and had it still back off when trying to save the old crush sleeve.

[@haneyoakie14]

Yay Kenny! Good work!

[@richardpatrick7701]

I do almost the same, just I mark the socket and count the turns, and use a breaker bar,rachet. Just did 4 pinion seals this past summer.

[@schuck9326]

Great job and tips. I have shyed away from seal replacements due to the crush collar. Now I know another way to do it. Thanks.

[@goldwingconepatterns2565]

I was glad to see the gloves were on when you had the fill plug in hand. Quite the metal sliver supply on the plug. Good tips on filling and making sure you know just how much to put in.

[@ironcross420]

Snappy make that socket for 12x12p drive line socket like yours, old tech I worked with said his Snappy at Ford said a 3/8" 12mm 12p extra shallow. The size of the impact swivels top was the special at time. I bought a 12mm 12p 3/8 impact swivel and 17mm for tranny, with 36" 1/2 to 3/8 ext.

[@gerryhuff4624]

Good video, I learned something new

[@markr478]

Loc tite on the bolts and pinion like factory? Maybe check diff. Vent for blockage? Just an idea.

[@chuckpearson9966]

great video thanks!!!

[@brad6665]

Vent tube or cap on top of axle should be checked for blockage so that pressure inside axle tube releases. I never use chrome sockets (usually 12 point) for impact, air or electric, they were designed for hand tool use only. Most people don't have in their tool inventory the black impact ( 6 point) sockets and 12 point impact sockets are usually found on the expensive tool trucks only.

[@brycelund7155]

Chrome sockets still have a lifetime warranty so send it.

[@wingman8447]

Great video. Thank you

[@watershedwonders1744]

Recently I thought its old, check the rear diff oil, that square drive was in so tight that the drive on the racht rung off. I did get it out and it did need some oil. Wish the last guy had taken your class

[@zeal514]

great video!

[@deetee3153]

Enjoy your content Kenny

[@Jack-ns5mn]

On that seal puller grind the tips rounded and if you are careful you wont damage the housing as easily.

[@HealthSupercharger]

Nice job

[@leonardhirtle3645]

Just working on the old 9.75 in. Ford. I think that was the original gear oil.

[@Toolaholic7]

The new crush washers,a pain to compress.Some older rear ends do not have a crush washer.Replaced the pinion seal in my dad's 1946 Dodge pickup,has a steel sleeve instead of a crush washer in the differential.

[@glennfields8121]

Brother Kenny, you are way too funny when hearing the sounds from squeezing the bottles of gear oil into the housing and you say sounds like Taco Bell! LOL I enjoy seeing you have fun while working.

[@gadasavideos8564]

Watched another video. Guy used a torque wrench to see how many inch pounds it took to turn shaft before loosening the nut. He then tightened nut slowly to achieve the same torque torque

[@brycelund7155]

Only accurate if the differential carrier is removed. This is the only way to get the nut tightened properly. This is the old school way and still the best way.

[@peterbenson3776]

I believe the numbers on seals and bearings refer to their measurements that would make a good short video..

[@StrongerThanBigfoot]

I do these on semis all day and I wish it was this easy.

[@oserratos]

"uhhh taco bell"... I felt that one haha

[@wolfbarber9272]

I don’t know why you marked that u joint. I only do that when I have to replace the carrier bearing to get all the u joints lined up.

[@alexanderzubar9593]

Do you verify the diff actually has a crush collar? Not many of them do. Ford 9 inch and some late Mopar 8.75 do. Maybe some newer ones do too. If no crush collar, then Kenny’s method works, you just end up with slightly tighter flange nut torque but no change to pinion preload because pinion preload is set with shims at original assembly. If it has a crush collar, this method could result in overloaded pinion bearings and burnout. With a crush collar, to maintain correct pinion preload and pinion nut torque, add a .020 thick shim washer on the pinion shaft before installing the flange, then tighten to your marks but not further.

[@haneyoakie14]

7:50 leverage is a wonderful thing

[@danmyshrall]

What kind of school did you get your automotive Tech training and how many years?

[@rustystubbs242]

Great video but I dont know about that shortcut. I always replaced that crush washer. Not worth risking a comeback and the increased risk of eating the cost of a rear diff job.

[@toddp3314]

Is this the same process as a 2001 8.8 or what I call a 10 bolt?

[@kenpickeringsr216]

I don't understand the three marks before disassembly. How do you know how many threads you used tightening the nut, as that is how the tension is determined. What am I missing? Thx

[@philspear73]

If you notice it took some tightening to get it to line up. Then he tightened a bit more past. That's how you know it's good.

[@needhelp2453]

You don't know how many threads. As you tighten your listening for the sound to change and you're feeling for the play to go away. When the play is gone and the sound changes abruptly, you continue to tighten until the mark on the nut is just beyond the pinion mark. The mark on the flange is just not that important. Also, he was feeling for the rotational torque to increase slightly.

[@mikea1973]

U are supposed to count the threads..u are correct..

[@needhelp2453]

@@mikea1973 if you remove the nut with an impact like he did and installed it with an impact, how can you possibly count the threads.

[@mikea1973]

@@needhelp2453 u bump the impact in small increments ..remove the socket and count the threads..its not rocket science..just like u count threads on a outer tie rod..so to keep the toe correct.

[@simike24]

Why do you not use impact sockets?

[@timmieclark9976]

Those impact guns can be rebuilt DIY if you want to keep it.

[@toddp3314]

Are the marks to keep the correct backlash?

[@brycelund7155]

The marks are for the pinion bearing preload. Backlash is set by shimming the carrier.

[@barrygrant2907]

Nothing personal, but my dad taught me cleanliness was next to Godliness when working on mechanical things, and only enforced when working on Air Force aircraft. It amazes me how many YT channels don't clean items before disassembling parts, even though they will often state--be careful this crud doesn't get into the part. Clean the crap off the parts before taking them apart. It does no harm and can only prevent future problems. I simply don't understand the reasoning behind not getting rid of grease and grime before taking something apart. I hate paying for a mechanic's work and being unable to tell if he's actually done anything, as it's just as grimy after as before.

[@eddiepond86]

This is a lot of the reason why I’d rather fix things myself. In a mechanics defense, they don’t get paid to clean.

[@bryanalbright3019]

Did you check the vent for air flow. Blockage could cause high pressure when hot. 😢

[@barrygrant2907]

@@eddiepond86 But a good mechanic cleans up before doing a dirty job and after. I'm not saying a steam clean is called for, but a simple spray and wipe goes a long way toward showing care was taken.

[@goodcitizen64]

I ran into the problem of not being able to clean stuff prior to repairs while in the US Army. We're in the field a lot and had no means to clean the area beforehand, the best I could do most of the time was a wipe down with a rag if we had any dang rags! The Army was much different than the AF...even when working on the helicopters and such! Working on the tarmac was a different animal than working on vehicles and heavy equipment!
