The large slide in our 2012 tracer 2800rld is acting up. It is the Accuslide type with 4 cables that operate it. Going out is no problem, But when you retract it is very reluctant at first. It initially doesn't move, the motors are turning but it doesn't. Then reluctantly it moves, but about half way in it starts making a grinding noise and stops. If you then pull on the sides from the inside while someone holds the retract button it will start too move again. Any suggestions would be appreciated. Thanks Bob Fears...RV guy if you read this your help is appreciated.
