I happen to be a GM certified mechanic and am very familiar with the shop manual. Packing the bearing is never mentioned. However, coating the bearings both inner and outer with the synthetic gear oil is. Liberally coat the bearings before install along with coating the axle tube or spindle, being careful to keep the sealing surface of the rear seal clean. That is how GM suggests this procedure.
What I read was very vague, so to be safe, I greased it which mix fine and wash out w the rear different oil. I tend to do more than less anyway. I was about to go on a long haul w the truck and I didn't want to take the chance of turning the bearing even once, dry. Of course I would have coated oil before letting it go dry. I appreciate the comment. I actually called a few chevy mechanics and they all had a different opinion on the matter so I went w the overshoot.
@@CopperheadGarage I have never used grease, but there should not be a problem, your grease will not effect the lubricating property of your fluid. Make sure to top off the rear end on a level surface, I usually pump the fluid in until it starts to run out and then quickly put the plug back in.
Thanks for the comment. The grease actually mixes with the oil and this was done according to the manufacture recommendation. Thanks for acknowledging that. Some people post videos without using the correct lrocedure which is clearly documented.
I know this a year old, but, I’m doing my oil seals on a 2012 GMC 3500 HD dually myself, I’m not a professional mechanic but lots of diy experience. I will be replacing the inner seals and axle shaft outer gaskets, I’m understanding how to torque the spindle nut, but not sure on the required torque for the 8 bolts on the shaft, I’ve seen guys do 120 ft lbs, 136ft lbs, and 146 ft lbs what was you torque setting on these bolts? I’m going to put a small coating of high temp wheel bearing grease on the bearings and seals when assembling. It can’t hurt to have some prelude. BTW good video on this repair.
I am about to replace my wheel bearings on my 03 Chevy duramax in a few days. Due to a high pitch squealing sound when I go above 65mph. Do I need to replace both inner and outter bearings or just inner?
On my 04 dully I put an extra wheel bearing nut in front of the nut clip it just s fit s behind the axle flange , never did trust the c clip and “ key way “ ! ( to hold it all together)
Honestly if you use a punch carefully and have a buddy who maybe has done the job before check your work after you reinstall your hub assembly, adjust parking brake and tighten your ring by reinstalling it with a punch in reverse and backing it off after tightening it a with a GOOD wack to the punch you can get away with not using the tool. (Remember to always back off and never try to go ahead to the next spot when installing your pin and ring since this is a delicate process lol)
I'm watching to see the seal direction installation. Which edge is installed toward the inner bearing and vice versa? Just for info; 97 GM book for 10.5 install (drums with seal and bearings) does not say to grease anything but the spindle. Spindle nut is torqued to 50 lbs/ft while spinning drum CCW and then backed off a quarter turn. The larger diff (11 in) does say to grease bearings. I see no harm adding some grease!
On the Axle prior to install... *There is a Donut shaped gasket that gets a Permatex #26 *This is to keep the Diff oil from leaking down the inside of your rear tires
I don’t understand why you would pack the bearings… In a full floating differential the wheel bearing both inner and outer are lubricated with the gear oil in the rear axle. Another question if that’s your thing, why would you only repack the inner bearing? Why would you pull the part and pack the outer bearing as well? Just a thought. Cheers!
I’ve seen a bunch of guys do it to 52 lbs then back it off and do 30 then you back it off retighten buy hand and put your key way and retainer on and bam it’s done that the 14 bolt full floating axel I don’t know now I’m confused
This was done directly from the manual. Some will say you don't have to pack the bearing. That's fine as long as you coat them throughly with the differential gear oil.
NEVER NEVER, pack these bearings with "GREASE", they receive their lubrication from the gear Oil, which should be applied to the Cleaned or New Bearing. I use Royal Purple 75w-140 here in Florida, if your in the colder North use the 75w-90
This has to be just about the poorest hub seal replacement I have ever seen. Never put grease on the bearings and where the seal presses on to the axle housing. Seal turns with in itself. You don't want the seal to turn on the axle housing. 40 year ASE GM Master Tech.
Th A Chevy 1500 and a 2500 are completely different in every respect. This video is very misleading. The axles are vastly different, the bearings are vastly different.
proper lubrication of the rear bearings is provided by the gear lube filled to spec, NOT grease!!!! DO NOT DO THIS!!! YOU WILL DISTROY YOUR REAR AXLE ASSY!!!!
It's by the book. Stop giving bad advice when you haven't even looked at the shop manual. The reason for the initial lube is so that you never run the bearing dry while waiting for the gear lube to get in. It all mixes in the end. I don't so stuff half assed. I do everything by the book. I bet you don't use torque specs either.
You mess your truck up and I'll keep mine running for a million miles. Yes, they are lubricated by the rear differential fluid that flows through the floating axle, but you should geese them when reinstalling so you never have a dry bearing before all the gear oil gets to it. I'm a professional. Read the shop manual.
That's the incorrect way to do it, but go ahead or you can follow the shop manual and do it correctly. I'm not going to do something half assed and make a video of it like most people do. I'm here to show people the correct way to do things. I'm not making a video of my opinion. I'm showing the proper way as GM requires. As an aircraft mechanic, we follow exactly what the manufacturer says to do because a lot more is at stake when you are just guessing on an airplane and if you don't follow proper procedures and there is an accident, you also face jail time.
Good stuff. Ill be saving this video for future bearing how to!!
You da man!

I used grease is that okay?

I would think that if you wanted something heavier than gear oil to pre lube the bearing assembly lube would be a better option
@@cm5838 Not needed, there is plenty of lubrication being provided through the axle tube, provided your gear oil is at proper level.
I like the video. It it helps to prevent metal to metal rubbing before gear oils gets there, it's good. A little grease in the the system won't hurt.
Thanks for the comment. The grease actually mixes with the oil and this was done according to the manufacture recommendation. Thanks for acknowledging that. Some people post videos without using the correct lrocedure which is clearly documented.
Awesome walk through, thank you for making this.

Where did you get that socket for that wheel bearing and what size is it

Where do you buy that size socket I've been to O'Reilly's and AutoZone I'm just stuck in the project right now

That was my thought as I didn't trust just oil.
What about the rings that go over the bearings?
called a bearing race. depending on miles, bearing and race should be replaced while in there.
Where did you get those new dust shields on the front? I can't find any at any parts store near me!
I stand corrected that's your rear. I need fronts and they look similar. I have a dually with massive drums in the rear.
Is this a dually model ?

Pretty much. Sorry for late response. Wheel hubs all are similar for the most part. Make sure you use the recommended oil for the job.
