Clunking/thunking noise

Knkfoster

We have a 2015 LS38RS and we occasionally get a clunking noise that we can’t track down. We had the unit at Lifestyle for warranty work, but they never heard the sound. We haven’t heard it as much since we left, but today we have heard it probably 50 or more times. We’ve moved today and the auto leveler has us leaning a little forward, but our iPhone level has us only at -1, so not significant.

Has anyone else experienced this? We’ve laid underneath the RV while the other has walked around, but it’s difficult to recreate the sound. The unit doesn’t feel like it moves when this happens, but I have felt some movement a couple of times. We’ve even heard it sitting outside, with no one inside. We’re flummoxed with no idea where it is coming from. Any insight would be helpful.

Our Bigfoot System will occasionally make popping noises. It only happens now and then if the circumstances are just right. What those circumstances are I just don’t know. I don’t know if it’s the temperature or barometric pressure or who knows.It hasn’t happened in a while. Lippert has a similar problem and it has been nick named the “Lippert Alarm Clock”. Here is a link to a few posts about the problem.

Mine does it also. I suggest you narrow down which area the pop comes from then give BigFoot a call. On mine it is one of the rear jacks. I talked to BigFoot when I was there last year. Got no real good answer from them. I try to reduce the weight on the rears by using boards under the tires if I stay a long time, Like a season. Over night I dont bother. Blocking up the jacks so that they extend minimally seems to help also.

Fulltime50/others,

If you suspect that it is the bigfoots, I suggest that you exercise them, not use boards under the tires.

That means for several stops where ground is fairly level and solid!, not just hooking, unhooking and using auto, but setting auto with slides in, then extending both rear manually to get a pretty good nose down, raise both front manually taking back about 1/2 of the nose down, then fully extending both rear, followed by fully extending both front. All wheels will be off the ground at some point, but keep raising. Set it back down in stages too. Then when at or lower than normal hookup height, hit auto level from a slight nose high position.

The back pistons are not as strong as the front. Add angle with the back, and do the heavy lifting with the front.

Not sure if this is any help, but Bigfoot tech told me to fully extend the jacks, leave for 15 minutes, then set your level, as desired. I would retract the rears, fully extend front wait 15 minutes, and then retract fronts most of the way, then extend rears. The fix I am referring to has to do with air in the hydraulic system, which may or may not be the issue.
