Howdy everyone, today we're sliding back under the 2003 Suburban 1500 to take care of yet another rear differential project, this time replacing the rear pinion seal of the driveline. Super easy and cheap project that can save you some serious $$$ in the off-chance you catch it before too much fluid has leaked out (yay preventative maintenance!) Hope you all find the video helpful and like always, feel free to reach out in the comments if you have any questions!
And happy pre-Thanksgiving everyone!
Parts List:
Rear Pinion Seal (GM 8.5" gear uses Duralast P/N: 710506)
-7/16 Socket or Crescent Wrench
-32 mm Socket
-Impact Wrench (some have advised against using one for this application, so I may have just been lucky - use at your own risk)
-Wheel/Hub Puller
-Seal Puller
-Rubber Mallet (helpful to seat new seal)
-Synthetic Grease (to help ease in the new seal, I used Mobil 1 but whichever you prefer)
-PB Blaster and/or breaker bar (if bolts are rusted on)

Generally, instead of grease around the outside of the seal you'll use RTV sealant to prevent the kind of seepage you had to begin with. On the instead rubber portion of the seal you can just use gear oil or vaseline. Regarding the pinion nut, the crush sleeve has already been crushed to spec, and it takes a lot of torque to make that happen, so if you just use some Loctite on the pinion threads you can just tighten the pinion nut to maybe 75 foot-pounds and not worry about aligning the marks as you have here, because 75 foot-pounds is not enough to crush the sleeve any further than it already is but it's enough torque to keep the pinion bearings under tension. Very good video though, thanks for posting it.

Using that puller to remove that yoke was a genius move 👍🏾

@spelunkerd 3 месяца назад

This is the way most shops would do this procedure, even though guys who work in driveline shops may roll their eyes. They would say you should reset the crush washer tension to reproduce the preload between the two bearings underneath. With the diff already installed, that's not so easy. Even though the torque spec on the pinion nut is really high, the final position for the nut is the more critical factor. So, just be certain that the exact same number of threads are still present after you're done, it's not so critical the white line you drew lines up exactly. Some would turn it a hair tighter to account for natural wear of surfaces internally.

@zeropoint7665 Год назад

Count threads not splines. Excellent instructional video😊

@connorhauss6044 Год назад

Went smooth on my 91 Silverado. Problem I ran into was filling the diff back up previous owner stripped the fill plug to nothing. Tried welding a bolt and wouldn’t budge. Filled from the breather hole and worked well no leaks.

@ZBrink11 6 месяцев назад

Pro tip: always remove the fill plug BEFORE draining differentials and transmissions.

@connorhauss6044 5 месяцев назад

@daviddelp868 Месяц назад

I know that having the tires on the vehicle (and on the ground) creates resistance against the axle turning when taking the large pinion nut off, but right now I have my truck on jack stands, with the drum brakes disassembled. So I don't have that resistance. I'd like to change my leaky pinion seal while I have the truck on jack stands. What should I do to keep the axle from turning while I try to loosen that pinion nut?

I have a torque wrench can I just torque it to manufacture specs?

@1Brain4Wheels 2 года назад

I think that could work, but when I looked into it, people said to measure the active/in-motion torque, not the breakaway torque (like what a standard wrench would set at) and so that’s why I just installed to the same thread count. Ideally if you can get a wrench with a torque gauge installed on it, that will ensure you get it dialed in just right!

@thesetruths1404 3 года назад

Also, when my opinion seal did that it was a rubberized washer that sat between the nut and the yolk that was either missing or all messed up and it was causing it to leak down the threads of the output shaft and that's what was causing me. It was not the main oil seal that you show tapping in. Was there another washer or anything like that on your assembly? I have an 87 so it could be different

Is it there a torquing procedure for the nut that holds the yolk onto the output shaft?

That’s why you count your turns and mark it when taking that nut off

How about you do it the right way and use a torque wrench

@tybrown4905 2 года назад

What’s the torque specs

@jscm3738 2 года назад

Because that’s NOT the right way. There is no torque spec. The correct way is to remove the whole carrier, & measure pinion preload. Nobody wants to do that for a simple pinion seal replacement, so this method maintains the original preload.

@autumnwoe6356 2 года назад

Very cool , thanks

@The_pipeliner Год назад

@@jscm3738 there is definitely a torque spec for the bolts holding the u-joint straps in place and that torque is 15 ft/lb. And that is a very important one considering the load it can receive if not torqued properly.
