I saw an axle locally on Craigslist that is from a ‘53 6400 that the guy is calling a 2.5 ton axle. Is that correct or would that be the 2 ton axle I would need? (for the P-30 spindle/brake swap)
Any suggestions on how to ID different axles? | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | First look in your shop/service manual.
It will describe and show different front axles and will also give specifications (usually at end of the section) for king pin diameter and so on.
For the 48-54 trucks, and likely a few years either side, the 1.5 ton axle is based on the 3/4 and 1 ton axle beam with same king pin but different hubs and brakes.
The 1.5 ton axle has a screw on dust cap over outer wheel bearings.
The 2 ton (and 1.5 ton heavy duty) axles have a thick flying saucer like dust cap held on with 5 little hex head screws. These axles also have 1.109" kingpins.
This only for 1.5 and 2 ton Chevy and for most GMCs of same size. Not speaking to GMC's larger trucks which could have even more different different axle options. | | | | | Joined: Mar 2009 Posts: 18 New Guy | | New Guy Joined: Mar 2009 Posts: 18 | Thanks for the help Grigg! | | |
