I've got a 1963 Galaxie 500 with a 9 inch rear end, and I'd like to do a refresh rather than a complete rebuild. A couple of questions:

What seals and bearings, etc. do I need to replace?

What should I look for wear and tear wise to make sure it's still in good shape?

I have a spare, so if I run into trouble, I can maybe use the backup as well.

Thanks in advance.

One thing I've learned doing rearend rebuilds, don't order any parts until you tear it apart. Then check all the old bearings and seals for part numbers and size. You'll need axle bearing/seals, carrier bearings (2) pinion bearings 2, and pinion seal. Either a new crush sleeve or a solid spacer (much better) and a 3rd member gasket along with new copper washers (10).

Thank you, this is very helpful! So I've got the axles pulled, but I didn't want to dig into the pinion cartridge or the third member in case I was digging too far. It sounds like all I'll have to do is pull the pinion cartridge and the third member to replace all of that, correct?

Sorry...if I sound ignorant, it's because I am. :)

Just pull the 3rd member as a complete assembly. When new carrier and pinion bearings are installed, the preload and tooth pattern have to be reset. Not a big deal, it's just that you can just throw them back together. They have to be (what they call) set up.

With Ford 9' cases there are two housing bores. There are also two carrier bearing hub sizes. In '69 Ford began using a "slim line" bearing to allow a big carrier to be used in a small bore case. Bearings are as follows.
Small housing/small carrier = LM 501310/501349 ( 28 spline stuff)
Small housing large carrier = LM 102910/102949 (28 or 31 spline)
Large housing large carrier = LM 603011/603049 (28 or 31 spline)
The outer pinion bearing is always 88010/88048
The inner can be (std) 88010/88048 OR (Daytona) 89410/89443
The tail bearing is R1535TAV on all.
The most common pinion seal is 7044 from National but there is a super large ('57) seal and very late ( mid to late '70s) seals are reduced to the same as the 8.8

Thanks for the insight!

Like I said, until you tear it apart, you never know. My 72 LTD I had a 9", big axle bearings, 2.80 gears in it. When I was done, 3.25 geared posi with 31 spline forged steel axles, because I used it for towing. Only thing original was the housing.
