Hello 2002 U270 what would cause the LF air bag to be 1" shorter then the RF? when i move the ride height vale they move together just off. Also who could tell me how to tell what slide lock is not working green, yellow light thank you for your help John 281 744 7699
John,
Correct. You have only one ride height valve in front, two on the rear axle. So any side to side adjustment has to occur on the rear.
How are your side to side measurements in back?
After the back is set, all you can do is set the fronts so that they AVERAGE the correct dimension.
One inch off side to side if more than is desirable. Do you have your individual wheel position weights?
