Replacing a worn companion base
When a companion slider base wears out, the trailer may feel loose or track unevenly behind the truck. Replacing the base restores the hitch’s intended movement, but only if the new part matches the layout of the old one. Work slowly, photograph the fastener arrangement, and set aside the old hardware so you can compare it with the new parts.
Replace worn companion parts as a set where possible, since a fresh base on worn guides or pins can wear unevenly. Once installed, couple the trailer on level ground, check that the slider moves freely without binding, and inspect the work again after several short trips. Keep a record of the fastener sizes used so future service is simpler.
- Photograph the fastener layout before removal
- Replace worn guides or pins alongside the base
- Recheck the setup after several short trips
