Do you regularly check and service your trailer?

Trailer servicing is just as important (if not more so) as servicing your car. Although they do not have an engine, they do have most other moving parts such as wheels, bearings, brakes, brake cables etc.
Trailer service and maintenance can sometimes be overlooked causing expensive and unnecessary repairs further down the line.


When fully laden, a trailer could weigh as much as three and a half tonnes!
Here at Ben Owen Services Ltd we take trailer servicing very seriously we offer inspections, services and general maintenance repairs on all makes of trailers.
