You are the most true to form realistic day garage mechanic I have seen. I will differ to you from now on on my gmc 3500 repairs if you have a video on it. Thank you for being a straight shooter.
I respect your hard work and dedication to this job. I watched it and learned a lot. Gonna rebuilt my 8.25 this spring! Peace and Blessings. I am subscribing.
Great video, thanks for taking the time to show all the details.
Great Job!!! Hope she holds up for you. I am in the middle of doing mine using your video. I had the transfer case replaced about 5 yrs ago and they left off the front driveshaft boot. This caused the front driveshaft to seize in the transfer case output shaft and it then hammered the output shaft bearings in the transfer case as well as the pinion bearings in the front diff. Unexpected, expensive repairs. I decided to attempt all myself and videos like yours are a fantastic help!
I’m about to attempt this and man you make it look about as hard as I figured it would be. Torches and home made tools lol.
Thanks for showing these I learn very much.
Great video. I just did a 8.25 and had a hell of a time removing and installing the pinion races. Seating was stripping out 1/2” all thread. Ended up hammering and pressing. It was a pain.
This was really helpful, nice job!
DADs FIX THINGs...!!! GREAT INFO... NAILED IT...!!!
I am doing the same job on a 2004 chevy astro. and you made a good point, since you are using the same gears and all that, I just do not see the reason to put paint marking on the gear.and trying to do if would were rebuilding the rear differential where is more to it, but your video gave a couple ideas for my project.
This vid helped a ton. You got yourself all other subscriber
Old school! Love it. Thanks for the great video.
Nice video!
For that shop press get the Harbor Freight Pneumatic bottle jack, it makes life so much more convenient
Good video didn’t see you add oil on bearings for pinion. But very detailed video .
Hey great job man will this work for 02 Escalade front diff
You need to put the silicone inside the bolt holes. When you put the silicone on first you get your hands and parts in it.
Very informative video. I have an 05 Chevy 2500 HD. I was wanting to know, and Ive been searching, if there was anything that can help with the front end? I was having my front diff worked on and I was asking if there can be a locker or a limited slip installed. Everyone was saying that because it is an IFS, whatever is in there is in there and cannot be swapped. Any thoughts?
Thanks for the video. @
How did you hold the yoke/pinion when trying to crush the pinon sleeve, I cannot get mine crushed to save my life!
