Mike, I have read your post, your PM on the old forum and your mail. I have been quite busy the last weeks. Hope to come back in the end of next week.

As you know I am not a "New member". I guess you found me on the old forum as "swedechev". If you take a look on my posts on the old forum you will also find a cople of posts I have made on topics from other members, some of them including issues concerning rear axle, differential, propeller shaft, ring and pinion gears etc.

@35mike You might PM Mike for some ideas. He's a pretty resourceful guy.

Mike,

I have some Chevy stuff, from the 1/4 elliptic spring era, in the woods. I am in Columbia (Central) Missouri. Where are you?

Mike

Per - Ake and Mike . I haven't taken the rear end apart yet as I am away on an old car tour with my 1930 Chev Coach. We drove 102 miles today and it worked great.

I live in Nova Scotia.

Per - Ake I have been reading your posts and look forward to any advice you can give. What rear ends will work?

Thanks

@tiny  Thanks for you help. Mike

Now I have checked my notes.

The only Ford T‑parts I used were:

One bronze thrust bearing

Two steel washers, one on each side of the bronze thrust bearing.

Note: These three parts fits 1922 490 only on the right side of the differential housing (On the left side you must have the ball thrust bearing that was new on 1922 models, with the new spiral cut teeth on the ring and pinion gears.)

I have also checked a couple of posts that I got from other members. Among them posts that mentions Ford T parts that fits 1922 490 models, at least the gears inside the differential.

I hope your rear axle issue is just a rear axle issue! If not, and if you need more help, I suggest that you search the old forum for similar topics. The quite efficient “Advanced Forum Search” is still available on the old forums. Note that you should include both the 490-forum and the 1912-1928 forum in your search.

I also checked some threads concerning rear axle and propeller shaft issues, threads where I made one or more posts.

If you have not taken the rear axle apart yet, I suggest that you begin with a test that can indicate a common issue on all 490 models: Heavily worn or completely vanished thrust bearing on the right side of the differential housing:

Jack up the rear end. Grab one of the wheels and try to push or pull the rear axle in the rear axle housing from one side to the other. There should be no axial play. If you can push it say 2 millimeters (0.08”) I guess that the thrust bearing on the right side of the differential housing (part # H391) has completely cracked and has been molded in the gears.

These bearings were made of a kind of alloy that enlarges and cracks by age. If you don’t find the thrust bearing, between the two differential thrust washers (#H117), most of it followed the oil as you drained it. The rest of the bearing you will find if you wash the roll and ball bearings and the differential parts in a can and after a couple of days takes a look at the bottom of the can. Guess how I know.

If you can push the rear axle less, but you can feel a distinct movement (axial play) there is a risk that the thrust bearing is more or less cracked and worn.

In both cases I suggest that you remove the rear axle and examine the differential thrust bearing (part # H391), the R&P gears and other parts as you can read in my threads and posts on the old forum, mentioned in my latest post, https://vccachat.org/ubbthreads.php/topics/260745/Drive_shaft_ring_and_pinion_ge#Post260745.

If you can’t feel any axial play when you push/pull the rear axle it might be OK, but it can also indicate one or more other issues.

Ford Model T had exactly the same lousy thrust bearing. A friend of mine, active in the Swedish Ford T Club, told me at that time (2012)  that problem with this thrust bearing is common, independent of if the car has been used a lot or is just aged.

Most of the text above I have taken from my thread https://vccachat.org/ubbthreads.php/topics/264632/new-production-ring-and-pinion-gear-set-1922-1924.html#Post264632 (December 2012)

As I mentioned in my latest post I used the Ford T bronze thrust bearing together with two thrust bearing washers. So now, twelve years later, I am sure this bronze thrust bearing fits and works well. After I had finished my extensive repair 2014 I have driven the car 13 000 kilometers (21 000 miles), so far without any issues.

@per-ake-larsson  Thank you for this information. I have not taken the rear end apart yet. I will be doing that on September 16th. I will do as you suggest.

I have ordered the thrust washers from Snyder’s and have been trying to make contact with Billy Possum but they must be away and not returning calls. I am hoping to order a propeller shaft housing bushing from them. I will refer back to all the articles that you have given me. Thanks for all you help. Mike
