The Stovebolt Site Forums The Shop Area Driveline Rear axle

Does any one know if there are differences in the axles on the outside of the rear axle casting my 54 has a axle from a 51 both are Canadian models .Would like to find out if a American made truck has any markings different so one could tell . I am trying to find out if one could see the difference as I have a spare rear axle and the spare looks different has 3 lines on one of the sides .I am inquiring because I am thinking again of changing to the 355 gears and the Canadian models need a carrier from a American truck as they are different.

Do you mean the axle housing or axleshafts?

The housing ,I have a spare rear axle and torque tube that had bendix brakes and I noticed three lines on the housing of the pumpkin can’t remember which side it is on as it is stored but was thinking if there were casting marked on the axle to identify were it was made . I will have to dig it out and take the cover off .Once I have the cover off how would you be able to tell what type of carrier it is.

I’m not sure, mine should be Canadian. I have a few axle shafts I could check, that’s why I asked.

From what I found out the carrier is different on the Canadian models so if you want to change the gears to 355 ratio you need to use a carrier from a US built truck.I was curious about the casting marks as my spare unit came from a unknown truck and was wondering if you can spot the difference without taking things apart.

I’ve heard that as well.

The bottom of the item ad say US trucks only. That must mean CDN trucks are out.

I think he’s aware of that. He’s trying to identify his other axle without taking it apart.
