has any one had good luck with replined axels? (31 spline shortened down to 28 spline).and if so are they as strong?

factory axles are case hardened. when you cut them down and respline them, they are a much weaker part. they will twist and break right where they come out of the spool. the left side will be the first to go...

Ive never heard of cutting down and resplining. The axle is narrower where you would be cutting it so it wont have enough there to respline. resplined.

I did have one shortened once and it never broke. It was cut, doweled and the end welded back on, the shop guaranteed me it wouldnt ever break near the area they worked on. It cost more than a aftermarket one, but I didnt know better at the time and I also needed it the next day.

not on a 9" ford. on most axles you have to shorten them 4" or more.....drag racers have been doing it for years. they don't hold up on the strip either...

Hey allan: I think I know where you are at,.. Do you have a narrower width 9" that has 28 spline axles and want to go to 31? I had the similar (if it is your case too) probelm. After much research I decided to get a new complete rear end assembly (60") that had 31 spline axles. The older 56" rears are getting hard to come by and so I made the switch. Don't try going from 28 to 31 or vise/versa. As outlaw stated, they WILL be weaker!!

I have had a few shortend( slow learner). If you use a 31 or 28 and shorten it past the point it necks down you can respline it with the same spline count like a 28 to a 28 or 31 to 31. The less they have to turn down the axle diameter the stronger it will be because of the hardening is so shallow. So like if you take a 31 and make it a 28 it will be weeker than say a 28 to a 28. But none of these shortened axles will be strong enough for drag racing or cicle track racing. I have tried both several times( slow learner, see the pattern) Now if you are shortening a after market axle that has long splines and only have to cut it, no problem and some can be resplined and still maintain there full strenght. So if i was you and I was, buy a new axle. I spent 2 to 3 times as much trying it the other way.

I have usesd both Currie enterprises and Moser's and have not broke either. I dont no if Currie installs bearing for you but Moser does.

We spot weld the collars on stock axels when we use them (not often), but not on aftermarket axels. We run superior axels and they have double collars.
