How Do You Know if a Trailer Brake Actuator Shock Needs to be Replaced

Published 10/15/2015

Question:

When not installed does this shock normally extend to fully open? What I am wondering is if there is some kind of spring that pushes this open? I have some horrible slamming noises coming from my trailer and other posts recommend replacing this shock. I took apart my hitch and this shock had good resistance, but it doesnt extend fully open on its own like a car shock, it just stays in the position you leave it. Is my shock good still and I just need to look elsewhere for the problem?

Shocks such as # DS12426 on brake actuators don't have a native, relaxed positioned. They will stay in place until acted upon by an outside force.

You will know your shock is good if it is very difficult if not impossible to push in and pull out by hand. If you aren't straining and pulling or pushing as hard as you can then there is likely something wrong with the shock.

Based on the problem you described it does sound like the shock is the problem.
