If your truck is “pulsing” – quickly speeding up and slowing down, or not driving smoothly, the driveshafts may be out of phase. Ensure both yokes are lined up with each other as in the picture – if these are out of phase it has a noticeable effect on how smoothly the truck drives.

This advice does only applies to shafts with universal joints (rather than CVDs) and Orlandoos seem to be particularly sensitive to this issue.
