I think that you have a very early rear axle assembly. What does the speedometer housing on the drive shaft look like? Dave, for some reason this thread has been split, maybe to free up Bud's original thread. Anyway, go to the top or bottom of the thread and over on the right side you can select th...

Brian, I have never seen seals there. They are to be pushed through from the diff side out almost to the brake end of the housing. Use a piece of 1" pipe and a set of Harbor Freight seal installers and a good LED flashlight. First make sure you have the old seals out before you try to install ...

Dave-
My truck is an April 1928. Pictures of the speedometer housing attached.

===============From Dave========== "Just a suggestion, before you get too happy with this axle, look very carefully at the bottom of the surface where the wheel bearing rides on the housing. If it is damaged here, it could have also damaged the wheel bearing and hub bearing surface. " ====...

Bob, thanks for the diagram and yes, my apologies to Bud for hijacking his "for sale" post.

How do we move this to the discussion forum?

I've cracked open my worm drive axle housing and fortunately have found it to be in great shape. Worm drive and gear look very good, as do the planet (spider) gears and axle gears. Only trouble area appears to be the seals, which I would have expected to replace anyway. So I have some questions: -Ea...

FYI, for jollies I just completed the same test but with the dual-high in low mode. It took about 3-3/4 revolutions to turn the free axle 1 revolution.

I've completed the test. Only difference is that I'm turning the input shaft of the dual-high since the engine & tranny are out of the truck. The dual high is in 1:1 mode (shift lever position is to the rear). I get about 2-2/3 revolutions of the input shaft to turn the free axle 1 revolution. S...

Thanks, Dave. I'm going to give that a try.

Hello Bud-
My April28 truck has no high/low speed markings that I can find on the rear axle, so I believe this indicates an early high speed. I hope to be taking it apart soon to verify.

Yes, forgot about the popcorn truck. That was nicely done. There was a stake bed over in the areas with the cars that was pretty nice too.

In addition, I took photos of several of the AA's that had driven in.

Bob M, was that your express bed? It looked great!

I went to Model A Day at Gilmore and had a great time. There were 4 excellent AA's in the museum, a school bus, firetruck, platform dump bed and service car. I didn't get a picture of the school bus.
