I would first try removing the shim and road test truck. Shim was installed to counter pull to left. It might be causing your truck to pull right now. Read the tsb I emailed you.

 

The shim fix it doesn't work and often gets stuck the the back of the rim and ends up in the wrong place during a tire rotation making things even worse.
Get rid of the shim.

Front feeling pull is often due to rear brakes not adjusted evenly.
Make sure the rears are adjusted correctly before doing anything else.

 

It might be that the left brake just is'nt working. or working as well.
