Rear wheel bearings

My GTV6 is definitely female. After years of trouble free running I decided to sell her and she is throwing tantrums. First the clutch disk, then the clutch master cylinder and now a rear wheel bearing.
I did one on a Milano about 15 years ago and I do not have fond memories of the job. So a few questions for someone who has done it recently or frequently:
Is the order of steps
1 remove big nut
2 Undo half shaft from hub
3 pull out spindle
4 undo locking ring
5 press out bearings

Is the locking ring LH thread on the left side?
Any tips for getting the locking ring out without the factory tool?
I seem to remember someone made a tool from a piece of pipe with welded nipples to match the castellations in the ring.
I have the bearing press tool.

Any other sage advice?

Thanks.

The answer to all the above is "yes". I've managed to wreck a number of rear wheel bearings (but more often the spindles themselves) on my ChumpCar. I have also used a hammer and punch in desperation to remove the lock nut. I do have the Starker version of the factory socket if you would like to borrow it.

Thanks for the offer. I plan to make a tool from a piece of exhaust tube and see if it works but I will get back with you if it does not work.
I pulled the hub and it is worn where it contacts the inner race so I will also have to find one of those.

If you have the castillated bearing retainer rings this will work. they are non-impact sockets so you can't use a rattle gun. I use a breaker bar with an extension, I also added a tube located and centered with nuts this aids stability as you pull on the breaker.

I was looking through some links I had saved for something totally unrelated and found this. It is an article showing the process for an alfetta.

I saw that too. It is helpful but it revolves around special tools that most of us do not have. A slide hammer replaces the two hub pulling tools.

I have all the tools for this, both style retaining rings, the tool for bearing removal, I have done this on my Milano and GTV6, but it has been a while and I suffer from CRS, but it will be after Memorial Day before I could get them in the mail. If her timing were better i could have given them to you at Road Atlanta a few weeks ago.

The job turned out to be easier than I expected, an unusual experience when working on a transaxle car. The second one took less than an hour.

Remove split pin from spindle and locking nut.

soak big nut in penetrating oil (ATF + acetone)

Break loose the six socket head screws that attach the shaft to the hub. I used a socket, short wobble extension and breaker bar. The handbrake held the shaft tight.

Undo the big nut with impact wrench (HF Earthquake)

Completely unscrew the six screws with air ratchet and tie the axle out of the way.

Knock out the spindle with a copper hammer.

Pull out the hub with a slide hammer.

Heat locking ring with MAP torch then cool with water spray.

Un-peen the locking ring and break loose with an air chisel. It came loose easily. Spun it out with a pin wrench.

Pull out the bearing with the factory tool. (I did one using big sockets and threaded rod on my old Milano).

A bearing race was stuck to the hub. Cut a slot with a Dremel and hit it with a cold chisel.

Next step - wait for new bearings and used hub to arrive.

No, just saw you driving the silver car around where the Alfa racers were.

Best of luck to you. My 1976 Alfetta GT had a right rear wheel bearing problem 2 years ago. It never made any noise. It had a loose wobble side to side. Turned out to be a loose hub nut that I tightened to specs with a torque wrench. The wobble completely disappeared after the re torque and not a problem since. Wish you well with the very difficult bearing replacement.

Which reminds me of the time I saw Joe Beninca do this job on a car at a race meeting years ago with the factory tools. Like, how quick it was..... .

Al Mitchell mentioned that they are very common bearings and there is no need to pay big bucks for them.
I am on vacation and I have almost two weeks to think about the rest of the job. Installing the new bearings and locking rings should be easier than getting the old ones out.
