Leveling Jacks making thumping noise

I'm new to the Newmar family having just purchased a 2016 Dutch Star. . .traded up from a Phaeton. Not sure if anyone has had this issue or has any ideas. I have been periodically hearing a loud "thumping" noise (2-4 times a night) in the rear of my coach. Sounds like a door slamming and is accompanied by the coach shaking a bit. It seems more pronounced when it is cold outside. I marked lines on the cylinders to see if the jacks were settling and that was not the case. I have retracted the rear jacks and the problem goes away.
Any ideas???

My guess is the hydraulic fluid is contracting with the cold resulting in the jacks making a sudden adjustment. That is assuming you have hydraulic jacks and not electric or even air stabilizers.

Check with the jack manufacture and I'll bet they have a different fluid type for use in cold temperatures.

Could also be a small amount of air in the fluid since your coach is so new.

Hawk Driver, we have a 2015 VTDP 4369 and have experienced the same issue during a couple of trips late last year. I brought it to the attention of the dealer and as usual, for these types of issues, it could not be repeated. We'll be at Newman the week of 3/21 and will have that on our list to checkout.

Hope someone has better information.

Tom

Welcome to the forum

We had the same thing only with the front jacks. For us it was a check valve not seating allowing fluid to bleed back. Try cycling the system a few times and see if that helps. If not your dealer or Newmar may need to explore further.

We have had the same issue with our 2016 DSDP, but in our case it was only about 45-50 degrees. Strangely, it only seems to happen at night...

Just wanted to check in and see if you have gotten any resolution to your problem with the leveling jacks on your coach?
Thanks

No answer yet

Contacted Newmar and they were going to contact HWH, the jack manufacturer. No answer yet. Contrary to my earlier post, the shudder happens during the day as well. Kept track of it for a while and we hit a high of 17 "shudders" in one day.

I have heard some popping in the back by the rear wheels when raising the leveling jacks. I was told by Freightliners that raising and lowering the jacks moves the coach forward and backwards as the jacks are moving. I have seen them move a little but not real much but you can see the tire trying to turn. I was told that this is normal. Sounds like your jacks are retracting a little due to leaking past a valve.

Does anyone have an answer to the mysterious thumping? We have a 2011 VTDP, we are travelling home from the south and spent the last three nights in truck stops. Our jacks were up, but 3-4 times a night we would get the same thump which would shake the coach. At first I thought we were bumped by a truck, it would wake me up and I felt I was going nuts. Now I know that I'm still sane, but a solution would make me feel a whole lot better.

Over the years several things have been tried with varying degrees of success. Try placing boards under the stabilizer foot. Theory is the metal foot pads are crushing the rocks under the pads, one rock at a time, thus the loud thumping.

Another fix that I have sucessfully used is to replace the hydraulic fluid with a type made for cold temperatures. The theory is as the fluid cools at night it contracts and the jack legs suddenly move as the fluid contracts.

Could also be a hydraulic valve leaking causing the thumping.

In our situation the 'thump' happens:
- only when the jacks are up (not down)
- even when the outside temp was in the mid 70's (so not that cold)
- when the jack control panel was not on (key out of ignition)
