62 Rear Diff Rebuild help

So I have zero experience with rebuilding rear differentials. I took mine to a shop to have them take a peek. They called me and said the gears and axles were good but that it needed seals and bearings. He said that was going to be $1200! That seems really high to me. I'm seeing rebuild kits for like $300. Can anyone give me some advice on this? If the insides are good how much should the parts cost to rebuild...how hard would it be to do myself...whats a reasonable cost for a shop to do it? Are there any parts would need to think about replacing other than the seals and bearings? Thank you!

New bearings and seals with gaskets runs about $360, from memory but the price has probably gone up a lot since I last built a rear end..

I personally never reuse a ring and pinion because it so much harder to set up a worn gear set, and a ring and pinion of your choice of gear ratios makes it easier to see paying for a new set of gears.

This assumes you have the hydraulic press, dial indicators, stands depth mikes and calipers to set up a rear end (it isn't like you see on TV were a gear set gets thrown in the case and within 10 to 15 minutes you have a perfect contact pattern to show the audience on TV). You have to know what you are doing.

It isn't rocket science but if you have no idea you are going to be buying a lot of gear sets, side gears or axles to replace when you set the differential up wrong. You can read a book and figure it out on your own, but it still requires tools.

Highly recommend you acquire the 1962 Shop Manual Supplement AND the 1961 Shop Manual (the 62 'Supplements' the data in the 61, you need both).

Section 5 has the data/info you made find helpful.

Are you racing your car or is it just a driver? Did you notice or hear any problem from it or did you just want it inspected? As if just a driver and no noticeable issues and unless you are planning a coast to coast run, I would just run it as it is. If you did notice a problem, I would just go with a good used.

By the way, I checked out the picture you have posted and just curious why you have your 327 Emblem up-side-down?

The total does sound a little high considering that would be about half the way to a custom 12 bolt rear end assembly from Moser. Note that isn't the muscle pack, but the some assembly required kit. Which just means you have to put the axles in and the brakes on.

I have never run the car. It sat for 20+ years before I picked it up so Im going through everything...and the emblems were upside down when i got it. haha

The car is completely torn down now...

Thanks Dave...I decided to pick it up from the shop...I'm going to attempt to remove the bearings and seals myself...then take to machine shop to get the new ones on. I'll probably have a shop look at the ring and pinon...I like to learn stuff myself but I feel like some things are best left to the pros. Thanks again.

Just drop the pumpkin, after pulling both axles out half way (push them back in when the pumpkin is out to keep dirt out and from banging your shins as you walk by the car).

Take the pumpkin and bearings with seals to who ever is going to rebuild it as they need to take measurements of pinion depth, back lash, etc. before it comes apart.
