Tomorrow I'll have the frame off/axle out from under, so my question is would you/I be able to tell which axle set I have by simply removing the end cap?
I don't know about seeing anything by removing the end cap but if you are interested on the gear ratio it is easy to do by turning and counting the drive shaft. Use something to lock one wheel/axle and turn the input shaft till the free wheel/axle turns two times. The number of turns will be the ratio. It should be 7 ¼:1 for Standard or 5 1/6:1 for High Speed.

Jerome, not sure, but I don't think so. Just do this. Secure one of the axles so that it doesn't turn. Counting turns, rotate the input shaft until the other axle makes exactly two turns. Number of turns on the input is your ratio. On the TT it will be 5 1/6:1 or 7 1/4:1
Oops, sorry, Jim
Robert,
No reason to be sorry, at least we agree.
Jim
Jerome, nope. Tried that with mine too. I already know mine, though, 22 mph.....standard!
Jerome,
If for some reason you can't figure out the gear ratio as has been described above I do believe that you can find out by pulling the rear cap. You would have to remove the following:
Rear cap, cotter pin, nut, entire thrust bearing assembly, and the Hyatt bearing. All of this will slide out when the end nut is removed. From there I believe that you can count the number of gears on the worm. 4 for low speed and 6 for high speed.
Are you going to take it apart? If so, just count the teeth on the ring gear. 29 teeth = 7 1/4:1. 31 teeth = 5 1/6:1.
You didn't ask this, but some free advice worth every penny your going to pay me: Since you have the assembly out already, I'd pull it apart, clean and check everything and install new seals, all 6. The outer seals can be done without taking it apart, but those two inner rear end oil seals require it be taken apart. IMHO getting the thing out of the truck is the hardest part. Since it's already out, I'd take advantage of the situation and go through it.
Just my $.02 worth.
