Jack snapping noises

Lippert recommends any of 3 fluids, 2 of which I believe are available from Amazon.

Torco RFF Grade 15

Maxima Fork Oil Grade 15

Caterpillar Hydraulic Oil Additive 1U-9891

I have put in the additive Maxima Fork Oil Grade 15 and it helped some but not extending the jacks all the way out helps also. The more you have the jacks extended the more they will pop.

My leveling Jacks seem to make popping noises whether we're moving around inside or not. My neighbor said that there is a fluid additive or a different hydraulic fluid that will stop this activity. He's not sure as to specifics though.

Question: Has anyone had a similar experience?

Any solution recommendations?

Thx

Yes!!!!!! You need add 1 or 2 qts. of "Caterpillar Hydrolic Additive 1U-9891 fluid (about $35 a quart) AFTER you have drained 1 or 2 qts. from your hydraulic jack system. If your popping stops with 0nly 1 qt. then do not add the second qt., if it continues then add the second qt.

Lippert issued a noticifaction addressing the problem with the popping sounds in Lippert Leveling system.
The popping sounds are the result of outdoor temperature changes. I only needed 1 quart and popping sounds went away and have not had to add any more additive. The popping nosies drove me nuts until I found the solution to the issue.

Thx for the info. I've thought about taller blocks... perhaps that's next on my list of "must haves"

Contact Lippert Hydrolics, based on my experience and others who had the same problem, the solution is not having taller blocks but rather adding the Hydrolic additive per Lippert's instructions.

X2, I went to my local Catapiller Dealer to buy my additive fluid.

These may help.

FWIW, in my experience, many times these snapping/popping noises are produced by tiny air bubbles popping. Usually, this has been caused by a bit of moisture (condensation) contaminating the oil and causing foaming. Most additives will bind with water molecules to help prevent this from happening.

Thx again... I'll contact Lippert tomorrow. Appreciate all the info.
