Is there a front and back to an axle? I have a good axle and need to install the perches, is there a right way and wrong way to do this? Thanks

No but check for straightness.

Perches must be installed correctly or you will have negative caster. Top of kingpin will be tilted slightly rearward.

Simply put, the axle has no front and back but the perches do. See the MTFCA axle book for instructions.

John, as others have said, there is no front of back in the axle. As long as you have a pair of left and right perches, they can go into the axle as you like. Once installed, then the assembly has a front and back. With the shackle holes horizontal, the axle should then be tilted back at the top. This sets tbe caster.

Hope this helps.

Well, with all said above is correct, there would be a front and a back to the axle if the spindle stub axles are already fitted to the axle, they are left and right as well.

Frank, once the frame is attached it would become obvious!

True Allan but only if the spindle arms are fitted!

I just changed the spindles around on my 1913 Speedster, the right side was installed on the left side and the left side was installed on the right side. While I was add it I rebuilt the front axle. I found the spindles were wrong when I was taking the left front wheel off to repack the bearings. You can tell, RH spindle should have Left handed threads and LH spindle should have Right hand threads.

It is important to have the shackles correct for correct castor. It is also important to have the spindles correct. They should be installed so that the nut will turn in the direction which would unscrew as the wheel turns forward. If you have them backward it is possible that the spinning of the wheel will tighten the bearing and lock the wheel from spinning which would be like putting on a one wheel brake and pull the car to the side. There is a washer with a tab which fits into the groove in the spindle and then the nut is tightened and the cotter pin installed which will keep the nut and bearing from coming unscrewed.

Arrange the spring perches so that the top of the axle is leaned back from the bottom, like so:
