The Left Y-Rod is wobbling, should I be worried?

The left rod that turns and controls the y-axis is wobbling, the right one is ok, the wobble is probably around 1mm's / disturbing, however no issues with prints, should I be worried? (I guess the wobble could cause the screws and rod to fall of over time)

Slightly unrelated, I also started a print with the extruder at +20cm's - instead of lowering, the printer/matter control pushed the head outside boundaries, forcing it upwards for less than a minute until I was able to reset things, after this unwanted stress test, the wobble stayed the same, so I guess the wobble won't increase with usage much

I'm a balance addict, so I would like to fix that wobble if possible

Thanks in Advance

 

Wobble on the Z rods is normal due to lack of precision in 5/16-18" rods. Trust me, you need the wobble.

 

Thanks for the reply and I apologize for the axis mix-up Yes it's the Z axis (confusion from too much abs fumes I guess)

Thanks for the replies
