I need to replace the inner and outer front passenger side axles on my 1988 ford f250 351w. I have no door tags but i took a picture of the axle tag. Can anyone tell me what the gear ratio is here? Im looking for a used truck for parts but i want to make sure that the axles will be the same.

Well, i can't seem to figure out how to post the picture but the tag reads..... 3 54 ◇ E8TA TO ◇ 610311-1

 

3.54 gear ratio.
you will also have to determine if it is a Dana 44 or a Dana 50
look at the locking hubs. if they are slightly smaller than the mounting surface of the front hub, it is a D44 if the locking hub is the same size, it is a D50
here are two pictures to show what i mean.
D44:


D50:

 

Thank You! Appreciate your time and info!

 

no problem.
and i just noticed you are a new user here.
welcome to FTE!!!

 

If you're looking to replace inner and outer axle shafts the gear ratio shouldn't matter, the axle shaft's will be the same no matter what the ratio. But as tjc said, Dana 44 or Dana 50 will matter.
