Basically that's it. I see your 5er is new, but for older units,
be sure to check the shackle bushings and suspension first.
This is a great post by member JBarca on replacing his axle and fabricating adjustable mounts so he could align the axles.
I used this
Correct Track II bolt on alignment system, but the one that JBarca made as described in his post is more exact.
Essentially when you measure from the kingpin to both sides of the front axle, the measurements should be within 1/4", and same tolerance when measuring between the axle centers on both sides.
