looking at your picture I see your motor mounts and threaded rod are sturdier then what came with my kit.

I upgraded my Z Axis recently to 8mm Acme (Lead Screw's): https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

This is a great upgrade to make on your printer eventually but does require you to change the printer's firmware. If you are comfortable doing that then it is a quick and easy $40.00 upgrade.

However, if you want to get rid of those plastic tubes you can use the following: https://www.amazon.com/uxcell-Motor-...+shaft+coupler

This will ensure your Z axis motors are secured to the threaded rod.

Another thing you want to check is your threaded rod for debris and make sure those nut's can turn easily. You may need to use a 3 in 1 oil to lubricate and clean the threaded rod's.
