Hi all, does anyone know how to tell what axle ratio the 46-48 passenger cars have? I read that 3:54 was standard in 46, but changed to 3:78 in 47 and 48. I haven't found any reference to data codes or vin codes that would help me identify which axle is in a particular car. Can anyone point me in the right direction? Thanks!

To determine the rear end gear ratio, look at the bottom of the center rib of the "banjo" (center section). You may find a set of numbers that will tell you what you have. 37-9= 4:11. 34-9= 3:78. 39-11= 3:54. As far as I know, there was no "standard" ratio for '46-'48 vehicles. If you lived in hilly country, most likely 3:78 or 4:11 was ordered. In the flatlands, 3:54 was common. Light trucks often had 4:44 (40-9) or 4:55, if they were 60 hp (41-9). Some axles were not stamped, or the stamping is obscured by dirt and rust. Rear ends were sometime cobbled together with junkyard parts. If I could name a "standard", it would be 3:78, as it offers a good compromise between speed and power. This message was edited by supereal on 8-22-13 @ 8:54 PM

A slight typo 3:78 = 9-34

Thanks for the correction. My old fingers and eyes, like the old gray mare, aren't what they used to be. That is why the 3:78 numbers were transposed and became 43 instead of he correct 34. Bob.
