Anyone heard the air pumping sound/noise when raising the rear height? I noticed the air pumping sound yesterday when my wife pushed the rear height mode to high while I was outside the car. Just wanted to check with you guys to see if it’s normal.

Thanks,

Yes, It sounds like it is going **** up lol. Mine has done it about four times now.

 

The pump cycling is normal. It should run a little when you first start the truck to bring it up to the proper height. I had a Lincoln with air shocks and it sounds the same, only that was all 4 corners so it ran longer, and you could here it from inside the car.

 

humm tss ???

mine does it too... its normal
