For the past few week, we've been getting more and more popping/twanging noises from the leveling jacks when they're down. First it was only on very cold nights. Reading a bit about it online, I thought their might be some air in the lines, but we've now pulled them up and down many times, and it still does it. Now it's 85 degrees out and I'm hearing it (and feeling it) in the middle of the day. And not from just one - sometimes from the front, sometimes from either side of the back.
When the jacks are up, the fluid tank is full.
Any ideas what's going on and how to stop it?
