Slight pull to the right after leaf pack install

Installed Icon RXTs on option 1, stock height in the front. I now have a very slight pull to the right. My thoughts are:

1. Screwed up something on install
2. Caster being effected from the rake
3. One side is sitting slightly higher and will eventually settle.

Opinions? On another note, my 30-10 vibration actually went away with the lift, which is interesting

 

Check if the leaf spring pack seats correctly on the axle.
So option 1

 

Changing rear suspension has an effect on overall vehicle alignment. Even if the rear thrust angle is "technically" not adjustable.

A good alignment shop can loosen then rear u-bolts and shove the axle around a little to get a better thrust angle. Don't expect them to do it at Firestone for 125$, but there are shops out there that will do it

 

You cannot shove the axle around. There is a hole on the axle seat that has to align with the central bolt on the leaf pack.

 

Yes I'm aware of the alignment pin. There's still room to shove the axle around. You can even grind down the pin for more wiggle room. I've paid alignment shops to do it. I've done it myself at work when we had an alignment rack. Just gotta think outside the box

But OP probably just needs a basic alignment. There was probably a subtle toe angle that came to light when the rear was lifted
