    I've been curious about this noise ever since I've had a popup. Was told by my father-in-law to expect it and it is nothing to worry about. My guess is it's the whiffletree twisting under load about 1/2 way up.

    I hear it on mine too. I guess it's normal, as mine was just serviced.

    When you are winding the cable up (or letting it out) the cable may start to wrap on top of previously wrapped cable, but then jump off to the next smaller-diameter winding on the winch. It is normal and to be expected.

    My coleman doesn't pop.

    At one time, the chain was loose. It would pop and slip during the last quarter of the way up. Supposedly, over time they develop slack. Removing a link solved the problem.

    Mine does it on the way up EVERY time at crank #36 or #37. It is the exact pop the exact same spot, so I just expect it and slow down at crank #35 and pick up again once it pops. 1996 Jayco Eagle 8.

    The only thing that makes a pop sound when I crank my top up or down are my old joints.

    My pup just pops at the very beginning but after that it's fine.

    Just wondering, where exactly do you think the pop is coming from? On my 2007 and 2008 Viking pups the lift arm covers were made in segments and could slip up and down freely as it was raised. Every so often one would go up prematurely and at some point in the process slip down till it was needed, and as it hit bottom would emit a "popping" sound.

    This is correct.

    The pop comes from near the winch inside the winch cabinet, so cable slipping as it wraps seems to be the correct answer.

    I don't know if it applies to your camper, but a loose chain is a common coleman issue. Google portal search will show plenty of threads.

    I assume you have a coleman. There is no "winch cabinet". The wiffletree under the camper doesn't have a big spool with cable that wraps around it. Possibly, other posters are thinking of other manufacturers. I suggest you remove the cover plate to clean and grease it. Do not try to crank it with the cover plate off.

    On one trip, my DD re latched the roof before I began cranking. She thought she was helping The lift system popped and slipped a few times. Every time after that it also popped and slipped. After a lot of research, I discovered that I stretched the chain and it was slipping on the sprocket. After removing a link, it has never popped again.
