On the first photo, I probably wiped my gloved finger on the race to feel for any irregularity. There are none, other than what you see on the photo. I probably had some dirt on the glove. At first glance the races look OK, but there is some...

Hummph! Here's a photo of the NEW race. When photographed with the same iPhone XS  Max, it shows microscopic grooves. Guess the old races are OK, aye?

Reminds me of the way we would clean our M-16's,with hot water for inspection.

Just completed an 1100 mile trip to a son in the hospital and when home found the Pax side streaked with oil.  (Takes Goof Off to remove it.)  The drive, both ways, was full of rain and wind and worry.  This topic got my attention and is full of...

Found a great video on using a punch to ensure the race doesn't spin on the spindle (called "peening"): semi truck wheel seals bearings races tips and tricks - YouTube

I am waiting on:

- 2 5/8 socket
- 2 1/4 socket
- Dial indicator

Then I will punch...

Not sure why it would tunr , but some do .  The Brits used tube spacers between the races to stop it.

Thanks for all your replies. Two things:

1. I will check the race-spindle clearance today.

2. For an enlightening diagram of "peening" the spindle, see: How to deal with a loose bearing race - Grainews

Some mechanics use Loctite with peening the...

Lewis,check the easy parts first,may be the gasket or the red plug could be old and getting brittle,or the pinhole in the plug could
be plugged up.Try some of the hub oil that comes in the white and red quart bottle may help with the leak.

Thanks for Loctite recommendation. Below is a photo of my spindle bearing race, showing that it was spinning. I hypothesize that very fine metal particles, or burning was making the oil bath brown.

I just punched the spindle in eight places(four...

Had to remove the hub, AGAIN!!!

Due to two unenlightened actions, the hub needed to be removed and reassembled with new parts, including a new seal:

1. I am ashamed to admit I installed the bearings from a different kit (Kit 413, Kit 406). This...

 They dont call it "Loctite" for nothing.    I would only use Loctite on the races for a permanent, last ditch effort.   The pin pricks should suffice .    FWIW The inner race  seldom moves, probably due to much more area and more load  .

A small bearing preload takes the last play out of the steering system.  Mine has a tiny play in the steering wheel with .001 and.003 endplay that was not present with a slight preload.

No I cannot tell you how much small is.

You guys are starting to scare me.  These are tapered wheel bearings.  Something that's been in use since at least 1909.  Granted the advent of using high pressure gear lube is a great improvement, but it wasn't so bad putting a dab of grease in...

Thanks for rolling (Pun) up your sleeve (Pun) and sharing your advice. The problem occurred when the outside bearing sleeve started to spin inside the spindle, making some metal which was caught in the magnet and causing the oil bath to darken....

My partner is an electronics engineer.  Our household is divided as...

The problem is that I got spooked by the 450 degrees F required to soften and disassemble a sleeve bonded with Permatex 64000.

Loctite only if the dimples don't suffice.  
 You can set endplay by mounting the tire, giving it a smack with a 10# er and then turning the nut .
 Barring that run it a few miles over the nearest RR crossing and recheck .
