How to Adjust Chains on Curt Weight Distribution System to Stop Grinding Noise

Updated 04/13/2025 | Published 10/11/2017

Question:

I have a Curt Weight Distribution hitch that was set up by the dealer when purchased. I now have the chains rubbing against the trailer frame making awful grinding noises. Is there a way to adjust the system to prevent the chains from grinding on the frame when turning?

If you have a Curt Weight Distribution System with chains such as # C17063, there should not be grinding noises when turning coming from the chains and this can be adjusted by switching the links in the lift chains. You can adjust the head tilt for correct chain length. I've attached a photo that shows how the chains should be set up. This comes from the directions, which I've also attached for you to take a look at.

I have the Curt MV Weight Distribution System w/ Friction Sway Control - Round Bar - 14K GTW, 1.4K TW. I have noticed that the chain link on one side is almost a full link longer counting from the bottom up. This their something I can do to even the links out or is it nothing to be concerned about?

I can definitely help you out but I'm not quite sure I can picture what's going on. Are you saying that the number of links aren't equal on both sides? If this is the case you'd just need to adjust one or the other (by tilting the head) so that the links are even. If I'm misunderstanding please just let me know!

Both bolts holding the chain to the bar have broken on my hitch. What can I replace them with and how do I prevent this from happening again?

@RobC the only option we have is replacement spring bars # C17074. It might be worth reaching out to Curt to see if they will send you replacement U-bolts or give you the sizing information. I have not heard of this happening before. It sounds like some kind of force was applied to the chains/springs/spring bars that should not have been. Even then, it would take a lot to break bolts like that unless they were severely worn. If it is properly rated and installed I wouldn't expect this to happen again.
