Lci clunking noise

2018 unit ? - obviously under warranty - I would have my dealer do the job !

It's not worth the problems of taking it to the dealership, letting it sit there for days or weeks just to remove a quart of hydraulic fluid and add a quart of Cat fluid, then have to return to pick it up. Much, much easier just to do it yourself. What's your time worth?

I'm 400 miles from the dealer and I am full time in this unit, easier to spend $20 and fix it today...

Smart move. Remember, after you do it to cycle all of your hydraulic systems (landing gear, slide outs) a number of times. I did mine just a couple of times at first and it still happened....but then I did it four or five more times and now the noise/slippage is gone.

Word of advice - take a look at the other threads on this subject and get the Catepillar 1U-9891. Others that have tried other fluids sometimes had to repeat the process. The Cat stuff is usually a 1-time and done fix.

Where is a good place to pick-up some Catepillar 1U-9891?

I had the same issues with what I described as the levelers buckling. It was worse when the temps dropped. I used the additive and followed lippert directions and problem solved. Tom

You need to find a Cat service center or dealer. They are everywhere. You most likely see their trucks when you are driving around. Wheeler is big around here, and their service center in Salt Lake City had tons of the stuff in stock.

You can visit https://www.cat.com/en_US/support/dealer-locator.html to find one in your area.

I called over one morning, they had it waiting for me in their will-call pickup. I drove over on my lunch hour to pick it up, and put it in the next Saturday.

The problem seems to get worse for some in the cold, but we had it happening in warmer weather too. One application per the instructions from Lippert and it never happened again.
