Maaaan, I been trying all day to find out what keeps the dang spindle nut from backing off. Because whatever it is, it is missing on both sides of my truck. Thank god i decided to finally fix my broken parking brake cables because the drivers side wheel was about to fall off… neither side had a retainer bendable castle washer or anything. I spent all day today running around to all the auto parts stores, and now I know I still ended up ordering the wrong thing. I even looked at those little wedge retainer things and thought “naw that can’t be it”… you have the only video so far I found that even mentions those let alone actually show them. Thankyou sir, thankyou very much
Thank you sir, you were very thorough and explained it well
Thanks for the video! This is helping me with my 82' F350. I'm new to solid axels so it's been quite the learning curve!
Glad to help
Very informative and professional, easy to follow! Thanks for sharing!
You want oil between the spindle and bearings. The viscosity of the oil keeps the bearings from spinning rapidly on the spindle and destroying it . If you put it together dry it will take time for oil to work its way in there.
Thanks, this helps. Very clear.
You're welcome!
Thanks for the video. You did a great job keeping the camera where it needs to be while explaining this. I’ve got the same rear end in my ‘01 2500 (manual tran trucks got the 80 rear too) I’d suggest cutting a groove out of the old race, filing off any leftover burrs, and just push it in with the old one. The groove let’s it compress a little and keeps it from getting stuck.
Good tip
your old timer was wrong buddy.You want .01-.09" of end play according to specs, its not enough to feel play by hand, but its just enough to allow oil to get between the bearing and the race. Thats also the spec on most oil bath bearings in heavy trucks too.
Good to know, thanks for sharing Zachary.
The hub assembly is different for 1994 and 2001 3500 dodge. The hub neck is longer. Also your drum brakes will be different.
Great video I subscibed. My 2002 3500 rear end locked up going down the road. I was able to put it in reverse 4 low and free it up then it drove home. What do you think would be wrong with it?
It could be a bearing or the gears in the rear. We also have a video on how to replace the rear. ua-cam.com/video/s3JeokVk3Fc/v-deo.html
@@Glennfix thank you!
Do you need to greese those or no grease
You do not need to grease, but I put some oil that I use in the rear end on them just to give them a head start. When the wheels start turning they will get oiled.
@@Glennfix feed from diff oil so use that to oil them ok got ya thankyou that man now in the parts book it does also lost a washer before the hub nut mine were missing and have worn the nut away lol
Thanks
No problem
Can you possibly tell me the part number for your seal ?? I’m doing this job on my vehicle with the same rear end as yours and I can’t find the seal anywhere
I don't know the part number but I got it from Advanced Auto
Thanks, the mech wants $1000 for changing these. Looks like he is gonna lose out on about $750.
Thanks, but I would have liked a little more showing and less explanation, as I have done limited bearing work, and it would have been easier to see than imagine. I am a visual person. My imagination is lacking. 😃
Where did you buy the bearings and seals from?
I got them from Auto Zone.
@@Glennfix Thanks
@@Glennfix Autozone? Thought you said quality was important? LOL. Good video bro. LOL
@@JohnLee-cb8ez There are Timken bearings. You can get different quality bearings from Auto Zone. Timken is top a quality bearing.
Great video Glenn. I had an issue with a Seized bearing that required me to cut my hub off. (Not good)
It looks like I have the same diff. I can't find the identification markings on my diff. Any other way to tell what year? I need to find another hub and the right bearings.
Thanks- Joel
Dodge puts the rear end information in the glove box. But if it is like mine It is not the first rear and I did not replace the rear with the one it came with. If you can get all the information you can find (numbers off the other bearing) You can go to "torqueking.com/category/1994-2002-dodge-dana-60-identification/" they are very helpful.
@@Glennfix thanks alot Glenn. I did Come across torque kings site. I will check the otherside bearings. 👍
If the rear end bearing is bad or noisy the bearing and race MUST both be replaced ..I'm not sure you are right about rear ends .. A couple months ago I sold my 2001 Dodge 3500 dually the rear end in it was a dana 80 hybrid .. I have 2 Dodge 2500 12 valves (1998 and 1997) they have dana 70 rear ends .. I have the build sheets for all 3 of these trucks ..
I sure hope you cleaned that socket before reassembly, that thing was nasty
Why not pack the bearings in grease before installing?
they run in wet oil rather than traditional grease
You are right, I just read the Dana Service Manual, free on the Internet, says to lube the bearing with rear axle oil prior to install and fill the hub cavity between inner and outer bearing races with oil too, see oage 70 of Sept 2013 manual
Cause he dont know this
