“Not all those who wander are lost,” a classic line from J.R.R. Tolkien that has been fittingly appropriated by RVers. Wandering the scenic hi-ways and bi-ways of this great country without an agenda or concrete destination appeals to the nomad in all of us. What is not appealing is having your motorhome wander all over the road during your excursion. Vehicle wander can be exhausting and dangerous, and should be addressed right away. Multiple components can contribute to wander, but most of time the culprit is found to be in the steering or suspension of the vehicle. In automotive suspension, the control arm, or A-arm, is a hinged suspension link between the chassis and the suspension upright or hub that carries the wheel. The chassis end of a control arm is attached by a single pivot, usually a rubber bushing. The control arm keeps the tire in its proper position in relationship to the frame, which aids in keeping the vehicle in alignment. The bushing is critical to the proper operation of the control arm so the vehicles alignment deteriorates as the bushing does. The new 01803668 bushing suspension cartridge REV A is a one-piece design with a metal body that replaces the original three-piece. You will find this same bushing throughout both the front and rear suspension on most vehicles with the Roadmaster RR8R chassis. Typically ten bushings used in each arena for a total of twenty, if replacing front and rear.
