Today at Alf's Mustang Garage, we replaced the pinion seal on a 9" Ford. Whenever you remove the yoke and pinion nut, its recommended to reset the pinion bearing pre-load. This video shows the process of that procedure. If you want to see the pinion seal replacement, you can watch that video here-------- • How to replace pinion ...

    We've done a few and typically just mark the nut, the shaft, the housing, and the yoke and even count threads exposed or length of shaft exposed, the reassemble to exactly the same point, using lock tight on the nut and not going any tighter. Changing seal didn't change crush or bearings or shaft length between them.

    Hey, I see that you set the pinion pre load on your bench. I see a lot of KZread videos that perform this on the car or truck. I like your bench top method due to my arthritis. Are there any issues with doing it on the bench as you did? Thanks again and happy new year!

  • @AlfsMustangGarage

    Setting the pre load on the bench is the proper way. If it's up in the car, you're now adding the resistance of the ring gear and axles which throws off your numbers. This type of differential must be done this way. I hope that helps. Happy new years 🍻

    @@AlfsMustangGarage I was going to say the same. Most would would call me a hack but you can tell, with experience, what 15 foot pounds of torque feels like and yea, you get used to what your impact can do. I sneak up on it, then I use a breaker bar with a cheater bar on it until the slop in gone and then sneak up on it with the breaker bar till I feel a little bit of drag. I can tell when there's two pounds but I check it anyway, I give it a touch more, if that's 15 with a used bearing, I leave it alone. If was 16 inch pounds... I leave it alone. One inch pound is not the end of the world, especially with a used bearing. It's a little more critical with a new bearing I suppose. I have many times marked a line on the nut and the the shaft, reassembled it, got to that line and when just a fuz past it. Sometimes nobody in town has the parts and you can't wait. That isn't technically correct but if you can't get the sleeve, you can get away with it that way. just make sure you end up about right inch pounds. Keep in mind, if you're reusing your old bearing you have to thoroughly clean it with parts or brake cleaner and then thoroughly oil it with gear lube, whatever lube that diff requires. Even with the right tool it's going to be difficult to tell the difference between 15 in/pounds and 16 inch pounds. I only cheat and mark and snug it a little more when nobody's got the sleeve and the customer can't wait. I honestly have never had a come back over that. I've never had a customer say, "oh man, that rear end growls now" or anything like that. If growled before, it's gonna growl after if you're just changing a seal because they want the leak fixed. Anyway...Guys that do this for a living know what I'm talking about. Most of the time I can get a sleeve or I have one on the shelf. I grabbed up a shit load of Ford 9 and 8.8 and the typical chev that was in everything till about 5 years ago...can't remember the size. I have every size there is for Mopar because I'm a collector. And I couldn't get a sleeve for my 57 Dodge. Guess what I did? LOL

    Hey....Sorry to bug you again. I was reading about Crush Sleeves vs. Solid. I'll be doing my Ford 9 inch soon and will reuse the original bearing just like you did. Should I consider a solid sleeve? Reading about both sleeves confused me somewhat. As always thanks for your guidance...

    I would use a crush sleeve if it's for a driver. Solids are good for applications where you know exactly what size you need to put the right amount of preload and typically used more in performance applications. I hope that helps.

    So the 8" and 9" are setup the same. The difference is the overall size. The thing is, you can use a crush sleeve or you can use shims. Either way is correct as long as the bearing has the correct preload as per your application. Daily drivers usually get the crush sleeve as where high performance usually get shims.

Could I get away with just pulling the yoke from my Ford 9inch, replacing the seal and then putting the yoke back on and torque it down to where it was or close to where it was? I know the right thing to do is to put on a new crush washer and do the preload stuff... Do you of anyone that has done this sucessfully? - of course no liabilities intended in your response...Lol

    It also depends on your setup. Some of these are setup with shims instead of a crush washer like in this video. If you have shims, you can swap out your yoke, tighten down a new nut to the torque specs and then verify the pre-load with an inch pound dial torque wrench. But at the end of the day you could always ask around to your local shops to see if they can do it. Shouldn't cost much if you bring them everything.
