Seems somewhat similar to your issue:
Summary :
- Check that all your screws and belts are tightned enough (but no too tight!)
- Ensure the frame is square
- Check the wheels for signs of ware out
- Disconnect cables to check for bent pins - take extra care when replugging each cable
In most cases, the above should fix this type of issue.
