Updated 07/31/2025 | Published 07/28/2025
Question:
Hi I have a demco auto slide for my fifth wheel. When I make a turn as it straighten it jerks. Is there an adjustment to stop this. I like the hitch other than that. Any help would be greatly appreciated. Thank you for your help in this matter.

Hey George, thanks for reaching out!
The Demco Autosliding Hijacker is one of my favorites when it comes to 5th wheel hitches. When did you pick it up?
Have you inspected the gear system yet? There is a snippet from the instructions (see attached photo) that mentions checking on the gear system periodically so that's where I'd start off looking.
Let me know what you find!
