the shims are in the right direction but appear too large. the idea is when going without an SYE and using a TC drop the shims will point the pinion input slightly higher then stock. when you drop the Tcase you create a bit of angle that then needs to be matched. lift kit shims generally cheat a bit more to try to alleviate ujoint bind without creating vibrations. they thread the needle between bind and vibration potential.
you will want to deal with this asap. any vibration is a bad thing. it will lead to diff leaks and pinion bearing wear. drop the shackles and lower the pinion input. it will steer better as well.
