JMO, but there is no such thing as 'a little' adjustment, as in easy. Without changing hardware either you move the spring hangers or the axles are aligned by bending them.
Wheels were out of alignment in my first trailer. Into a truck shop it went. All kinds of hydraulic machinery to bend axles later & a near 4 figure bill, all was straight.
Next trailer had issues with frame cracking in the area of spring hangers. Into another truck shop it went & came out with completely re engineered spring hangers, much stronger, & again near a 4 figure bill.
Managed to bend a axle in a humongeous pothole south of Calgary, AB. This time I figured I had choices.
A: Into a truck shop again, bend axle to fix & get 4 figure bill.
B: Buy new axle & have shop install it, resulting in a $500 plus bill
C: Get Correct Track system & install myself.
I went with plan C. Actually I did one better than that. I installed the correct track system & I also bought a new axle as a spare. Sort of like the boater who carrys around a spare prop, a spare starter, a spare raw water pump, spare all kinds of things because he can't walk on water to go get help.
Anyway my spare axle rides around in my basement. If I am ever days away from getting one shipped to me but have a shop under my nose out in Yukon or some such place, I am set.
There is a be prepared boater in me that will never die.
The only negative thing about the correct track is that it raises the trailer by 1". This inch can make all the difference if you store in a shed & height is close.
I am close.
Next tire replacement I will go with a tire not quite as tall & come down 1/2" in overall height making my net increase in height 1/2" with the correct track system.
There are always many ways to beat an alignment problem.
