Hi Jeff,
Here's a couple of things to try out.
1. Make sure the focuser and connecting sleeves, adaptors are firmly in place and the focuser itself has no play whilst focusing in and out.
2. The locking screws for the primary mirror only need to be finger tight, not too firm. Once that is done see if the primary mirror is able to move around by pushing it from behind. If so, check to see if the adjustment screws are threaded into the mirror cell, also, check the clips holding the mirror in it's cell. They should only tightened up enough to touch the mirror's edge.
3. Check the lock screw in the centre of the secondary mirror holder. Again it only needs to finger tight as are the collimation screws.
Good luck!
