How to fix Z-axis wobble?

I'm not sure if my rods came slightly bent, or if the milling on the couplers isn't quite centered, but I am getting a wobble on the extruder head of about +/- 1mm from side to side when the Z-axis motors are moving the extruder head up or down. Has anyone else encountered this? How did you correct the problem?

It's the 8mm x 300mm threaded rods (vertical rods). One side wobbles a lot more than the other side. I'm pretty certain that it's the rods that are bent, and not a problem with the couplers.

The parts that are bent are the M8*L300mm Z-axis threaded rod (part #4 in the part list).

hi,mespilus.please find a reference plane,and press the threaded rod with rubber on the reference plane.Remeber not use the solid object and not destroy the thread.if it doesn't work,you need to change a new threaded road.thx
