Wheel Alignment and New Axles

I now have a pair of axles on order and should arrive in the next few weeks.

My manual goes to great length about aligning the wheels and axles, and it doesn't look like I could take it to the local tire store to have it done.

With tandem axles, do I need to worry about this? I figure I'lll probably end up replacing the tires due to sun deterioration long before I would actually wear them out.

Your new axels should be fine, just bolted in. They are factory set up for the load and bolt in location. I had a new Dexter axel on my Argosy 3 years ago and it was plug and play. The only real thing to check would be the distance from the same place on the axle tube or backing plate on the hub to the center of the hitch coupler. It should be the same on both sides. It probably will be, but there are stories about axels being mis located in the frame (the frame was the problem) from the factory.

The elaborate bending of the axle tube alignment process that is outlined in the service manual is seldom needed, and requires some searching to find a place that knows how to do it and has the equipment to do it. That usually would be a speciality location, like a horse or utility manufacturing outfit, or repair outfit, or some truck, trailer and front end specialists. Again, not commonly needed anyway.

My new bolt in Dexter tracks true, has no tire wear in close to 14,000 miles, and all we checked was the coupler to axel dimension on both sides. There was a tiny amount of adjustment available in the bolts that mounted them, and we used it to bring those numbers within an eighth of an inch as I recall.

I would suspect that if you have not have a tire wear problem with current set up as long as you use the original mounting holes you should be good to go. The string from the center of hitch to axle is a tried and true method which is what I was told when I got my 8000 torsion bar axle for my heavy duty utility trailer in 2002. It could not be asked to tow any truer.

I am in the process of upgrading to 5200 lb axles and the factory bolt holes are correctly spaced for the new axle. All I will have to do is open the axle tube opening in the side plate and I should be good to go.

You will probably find there is a goodly amount of movement in your bolt holes which will allow you to move axle a bit.

My new axles have elongated bolt holes in the mounting brackets which will cover perhaps up to 1/2" inch of movement.

The center to center hole location on my Sovereign frame is around 9.050". I have gages fabricated that go from 9.040 to 9.070 C-C and I would not be surprised if a 9.080 would not align due to the hole size differences on the high end and 9.030" on the inside dim. FWIW my holes run .035" to .039" oversize of the bolt diameter.
