axle length on a 9 inch rearend?

I brought my axles into Currie Enterprises in Anaheim, Ca. for them to duplicate my 9 in axle w/ the ball bearing instead of the taper bearing type, so I keep it the same as the p***enger side. They said okay & said maybe I should leave the p***enger side to see if it's bent. I got them back today and they are both the same length. Isn't one side suppose to be longer than the other side?? I could have sworn one side is longer!!....Help! I'm second geussing myself!!

Thank you....

 

Oh Yeah! it's a 1958 Ford Truck rearend. The length I measured was 29 3/4" from the back of the flange to the end of the 28 splined end.

Thanx..

 

As I remember it the 58 ford truck had a longer axel on the left (drivers side) than the right. I haven'r seen a stock 58 axel from ford with a tapered bearing. The normal bearing is a 88128AR bca on the truck and station wagon and all the HD stuff.

 

It depends on pinion offset. Measure it.

 

I had a 1959 Ford F-100 9 inch rear end under my 48 F-1 ... years ago. I pulled both axles and had new axle bearings done at NAPA. I believe they were both the SAME LENGTH.

I remember looking them up in a Hollander exchange ... and it seems that they were listed as 30 inch and right side and left side interchanged.

 

You didn't mention the model of the truck, so I'll ***ume it's off a F100.

Hollanders says the axle is 30" long and the same for both sides. Fits all F100's from '57-'65, except P/trac. Ford p/n B7C4234A

 

My experience with Truck axles 57 to about 70 both axles are about 29 3/4 as you stated

 

IME they have always been the same length...

 

Well here is my follow up on my axle situation. I talked to Currie & they said measure from the 2 o'clock position stud to the end of the housing flange for measurement of 22 5/8"on the driver side of the 3rd member. and then measure for the measurement of 22" from 10 o'clock position stud to the end of the housing flange on the p***enger side. It was those measurements!!!!... So he said I can use those 29 3/4" axles for the Driver & P***enger...So I'm up and running by this weekend!!

Thank you & I hope this helps someone else if they are in question...

 

Some 9" fords have an offset pinion, some don't. When I say offset, I mean if you view the driveshaft from above, it runs at an angle. May seem crazy but a driveshaft does not know if it's angle is up/down or side/side.

good luck

 

If you have the same length axles on a 9" Ford, your pinion is offset to the right approximately 2 1/8". If you have one 9" Ford axle that is longer than the other by 4 1/4", you have a centered pinion.
