Open Roads Forum  >  Class A Motorhomes  > Freightliner POP Noise This Topic Is Closed  |  Print Topic  |  Post New Topic  |  Oldest first Newest first  Page of 2   Next jking2000 • View posts Partlow, Va Senior Member Joined: 11/14/2000 View Profile Offline Posted: 09/08/10 05:31pm Link  |  Print  |  Notify Moderator The last few times, I started up my Cross Country there was two pop noises. I would leave the jacks down, and air up the system. While the system starts to raise the chassis, there is two pop/bang noises. I watched the airbags and all four air up fine and look fully inflated. Hoping someone has had this before and maybe its something that needs to be lubricated or checked. Also, it is only when I have dumped the chassis air, and lowered the motorhome. Thank You for your Help! James 2010 Damon Tuscany 4078 (Pusher) 2006 GMC Envoy Horsedoc • View posts Dixie --- N. Georgia Senior Member Joined: 09/30/2002 View Profile Offline Posted: 09/08/10 05:42pm Link  |  Print  |  Notify Moderator Had it happen just yesterday. Loud pop on the left rear as the coach was coming up on the bags. A lesser one also on the other side. I have no idea where it comes from, but it is sorta scary when you are 1300 miles from home. Our coach is on the Freightliner chassis. It has just been serviced at Gaffney prior to the start of this trip, so I figure if there was anything amiss, they would have found it. Drove fine all day and was level parked. I guess we just don't worry until something falls off? horsedoc 2008 Damon Essence 2003 Honda Element Blue Ox tow chastho • View posts arkansas Senior Member Joined: 07/27/2005 View Profile Posted: 09/08/10 05:53pm Link  |  Print  |  Notify Moderator Try raising the jacks before the air bags come up. jking2000 • View posts Partlow, Va Senior Member Joined: 11/14/2000 View Profile Offline Posted: 09/08/10 05:57pm Link  |  Print  |  Notify Moderator chastho wrote: Try raising the jacks before the air bags come up. Sorry for the Confusion, the time prior to this I dropped the jacks first. So decided to try raising the wait off the jacks prior to raising them. Same Noise!

There is a big pin on both sides of the cylinder near the bottom with a plate with two bolts holding it in. The cylinders are not rigid mounted and can move in about a 6 degree arc. They may be just popping as they move on the pins. Mine do it once in a while.

I assume that it is the air bags seating and stuff moving around. My Kharma ran over my Dogma.

It can be either the jacks "popping", or banging as they seat in stow mode, and/ or the airbags "popping" back into shape after being deflated and squeezed down by the coach.
