Probably a 4.11 or 4.56. My bet it is a 4.11 On Sun, Jun 2, 2013 at 12:58 PM, Tom Johnston wrote: > ** > > > Hi truckers > Trying to figure out the rear end ratio on my 46 3/4 ton.

RE: [old-chevy-truck] Rear axle ratios
Did the other wheel turn at all? Here are the possibilities: 1. If the other wheel turned the same direction as the one you turned by hand (not likely - only happens with posi-track rear ends) then you truly do have a 2.25:1 ratio rear gear. 2. If one wheel was still while you turned another (probably what happened to you) then you need to multiply the number of turns by 2 (2.25 x 2 = 4.5) and most likely you have a 4.57:1 ratio rear gear. 3. If one wheel turned some, but not as much as the other, you need to put it back on the ground so it doesn't move and try again.

I read an article on the web which says to jack up the rearend (both wheels) and turn one wheel a complete revolution while counting the revolutions of the drive shaft. I did just that and my drive shaft turns a little more that 2 1/4 turns ( the other wheel does not turn). Is this procedure correct? If so it does not make sense.
