Front end shaking on turns

[MyExplorer58]

I just had my transfer case replaced along with the motor that is part of it, and now when I turn even slightly the steering wheel shakes pretty bad. Any input is appreciated! Before the transfer case broke my Explorer was shaking until I accelerated, then it would stop. Now the transfer case is new, the shaking is still there. I am concerned that it is even safe to drive.

Welcome to this forum! There are several possibilities such as an improperly balanced driveshaft, bad alignment or wheels which need to be balanced. Are the halfshafts or u-joints making clicking noises? How are the mounts & balljoints?

Sounds like there's air in the power steering.

With the engine running cycle the steering back and forth several times to get the air out.
