New end caps on 9" Ford

Guys:
I have a narrowed Ford 9" rearend In my 32 coupe that I need to put new end caps on, I am not changing the width just changing the end cap. I have read numerous post stating the pros and cons of using or not using an alignment bar for rearend narrowing and my question is. Since I already have the axles cut to length can I use the axles for my alignment bar? In other words put in my new center section and after verifying and adjusting for the correct flange width put the end caps on the axles with the new bearings, insert the axles in the housing and center section and align the housing to the end cap and tack in place. Then remove the axles and slowly weld by alternating my weld from side to side and end to end. All of the brackets are already welded to the housing so there should be no additional warpage. Opinions?

No.. you can't use the axles to line it up...I have the tool to do them..And the way it's made..Is the shaft goes through two collar's that bolt to the center section..If you try to do it with the axle, It will only be through one side of the center section..When a axle is in the center section it has a little play..towards the end...So I wouldn't do it like that..If you were a little closer,I would help you out..I'm set up to narrow 9''...Good luck..

What Dan says is the best way to do it, as the full-length bar will locate both ends perfectly. However, using the axles will work as long as your axle tubes are not bent. Think about it, you are using the axle's splined end as the primary location point. Once that end is "located", the only possible misalignment will be concentrically around the axle's diameter. As long as the tube and the end to be welded are concentric (lined up with each other), there cannot be any misalignment...

Yes, and it's working perfectly. I think you're missing some basic engineering here. And you're right, you'll know real quick if it's not aligned. Just feel for any binding as you go...

The problem with using the axle's to hold it straight is, There is play in the splines between the axle spline and side gear spline. If it's off, it will put stress on the side gear in the case and tear them up. It might be cheaper in the long run to make sure and do it the right way.
