Ford 9 in Differential Gears Assembly 

Debating about rebuilding the one i got with my projectv or getting a new one, you helped me realize i can rebuild, and i need a hydraulic press cause you make it seem well worth the money!

Thanks so much for the detail you put into this! I'm working on a recently acquired '68 Park Lane, which has a leaky axle seal and a leaky pinion seal. I don't think I'm going to completely rebuild the rear end unelss I find it full of glitter, but this is the best series of videos I've yet seen on how it all comes apart and goes back together. Good luck with your '64! I had a '65 for almost ten years and loved every minute of it.

Hello. How frustrating to find out you had the wrong bearings! Glad you were able to get it dialed in just right. I like how nice the rear axle looks. George B

I saw that you had the small bearings and were never going to be able to set anything. I had the same thing happen to me one time. The easiest way to set backlash is to run both adjusters in until you have all the side to side play out of the differential housing with a good amount of backlash. Then run the ring gear into the pinion until you just have zero backlash. At this point you can put the lock on the adjuster on the ring gear side. Now start tightening the pinion side adjuster until you have the desired backlash. That way you set your backlash and case spread (bearing pre-load) at the same time. I didn't see you pre-load the carrier bearings. They need to be pre-loaded just like the pinion bearings. I also noticed that it appears you have a non-hunting gear set. I saw a mark on one pinion tooth and two marks on the ring gear. You are supposed to "time" the pinion to the ring gear or you may get ring and pinion noise.

Excellent! I always wondered how that was done.

Hey Matt, Great video. Do you have any footage of you prepping the rear end for paint? I am getting ready to swap out the rear end in my '67 Galaxie 500 for a 9". This video and the tear down video were REALLY helpful. Thank you!

Hi, could you let me know what repair manual were you using in your video that was on the work bench? Thanks for the video and information.Ken

Hey, just came across your channel tonight. Watched a few of your videos. They are very interesting and this one in particular was very informative. I was surprised to see the coil over shocks. Are you using those in the front to replace the original coil springs since your working on the front suspension? If so, I've never seen anyone do that before. I've seem them in the back a thousand times as a band aid for worn out leaf springs. The original front coil springs are very stout so I'm wondering if those will adequately hold up the front, or are you trying to lower it a bit? You've got a big project there and it will be interesting to watch your project to the finish line. Thanks for taking the time to make these videos, it will help others with their projects. Keep up the good work.
