Three pix with questions

Seeking advice again 1. Lippert leveling system leaking oil under our Jayco (2018) class C. I couldn't see the pictured labeled. I thought it would have model information. Everything is covered in I believe ATF. Should I just hose it down and search for the leak? Anyone have experience?
2. Hellwig helper springs. Way out of adjustment, correct?
3. As seen in the Hellwig photo a rubber bushing between the frame and the body. Looks like its shot, Should I be concerned ?

1. I would use a degreaser and rags and wipe down really good. Less messy and it will do a better job; rinse off with water after if needed. I was troubleshooting my system and needed to get it clean, it was not a leak issue.
2. Yes, the helper springs need adjusted.
3. The rubber bushing needs replaced, but I doubt it's an urgent issue.

Thanks for your response. Jayco responded today about the bushing issue and recommended a truck repair shop to do the work. Like you said, I don't think it's a urgent issue but I expect a expensive project

1. My 2020 uses the Lippert Level Up system. I wouldn't be surprised if yours is the same. Here's a spot for manuals/troubleshooting help:

2. If you haven't found it already, here's a recent thread with suggestions to adjust your helper springs. A 7/8" ratcheting box end wrench comes in handy:

Picture #2 and #3 show me that your rear suspension is in need of attention. The rubber bushing you call is actually a "Bump-Stop" that is the end of the suspensions downward travel. It appears that you may have more weight on this axle than it was designed for, or your suspension is in need of attention. Pic 2 also shows your helper springs in full contact, but your primary leaf springs are bent beyond the typical arch.

I can say that this is not that uncommon, We had this same issue on our old Class C on a G30 chassis. We resolved it by a Truck Spring shop where they installed heavier leaf springs and essentially eliminated the need for overload springs. It drove so nicely after that work was done.
