Question:

The rubber pad on my Trailair Rotaflex Pin Box has shifted back about 1-1.5 inches. I blame I-70 through Ohio and Indiana. Can the pad be moved back into position some disassembly/assembly required or do I need to get a new Pin Box?

Expert Reply:

I reached out to my contact at Lippert and this pin box is not serviceable. Is there a chance you are using an autosliding hitch or something that might exert some leverage on that cushion area?

The replacement pin box would be the Lippert # LC328330 (1621 Bolt Pattern - Rated 18K) Trailair pin box with rubber compound to absorb shocks.

Another option is the Lippert # LC179879 Trailair Flex Air rated 18,000 pounds and 1621 bolt pattern with an internal airbag and a shock absorber to give a dramatically smoother ride.

The MORryde # MR84VR cushioned hitch that you referenced would be a good in between choice between the two Lippert's. If my budget allowed - I would like the FlexAir. The MORryde cushion I think is superior to the basic Trailair.

Otherwise, stay off I-70!
