X axis binds at 300 ipm in one direction only

looked on the forum and I have not found anyone with the same issue. If the X axis is moving from the front of the table to the back of the table it works just fine jogging or rapiding from point to point. But if I am going from the back of the table to the front of the table either in rapid during a program or jogging the lead screw binds up. I have had the table for nearly a year and have had no issues with it previously this was the first time. I played with the adjustment of the lead nut. It jogs in both directions at 200 IPM with no issue. After the weather warms to above zero again I will try lubricating the lead screw and see if that helps any. But if anyone has any ideas please let me know. Thanks
