I was having excessive wheel play in our Monaco motorhome steering. Henderson line up recommended replacing the original steering box with a TRW steering box. The box was replaced promptly, adjusted and tested. The motorhome steering now responds correctly and smoothly without any play. I should also mention on a separate service, we had our shocks replaced with Koni shocks which made a super improvement in the ride of the motorhome. Henderson's Line Up are great professional people to work with. We highly recommend their services. A special thank you to Scott, Kote, Don and Eric.
