Y-Axis Completely Out of Whack

My Y axis suddenly is completely out of whack.   It's position is not correct, it's crashing.   After attempting recalibration it will initially be right for a super brief time then act up to the point you can see the printer glitch, then the Y-axis coordinates are completely wrong (like zero becomes wherever it was when it glitched).   I've updated firmware, ran calibrations over and over and no luck.    Should I move on to Y-axis motor replacement?    X and Z seem completely fine.

RE: Y-Axis Completely Out of Whack

Have you cleaned and lubricated the Smooth Rods and bearings? 

Have you checked that the Idler roller is rotating freely and smoothly?

You were absolutely correct.  😀

I took off the Y-axis motor so i could move the table and it was very sticky in one direction and marginal in the other direction.   I cleaned the rails and used the prusa lubricant and it is butter smooth now.   I also cleaned the X and Z rails and lubricated as well.    Thank you for the input, I was thinking the stepper motor was bad but it was not.

Thank you,
Ryan
