CURT Q20 Slop and Noise

Hello,

I'm a fairly new fiver hauler. I have a CURT Q20 and R20 slider combo on my F350 that was installed as part of the deal on the new truck. I've towed a 11,000# Grand Design about 7,000 miles total between many campsites. I religiously maintain the hitch, greasing according to the manual and etrailer's youtube video. I use the teflon plate that came with the hitch. Just about every time I hook up, I spray the jaws and the pin with heavy duty silicon.

I noticed that after stopping, like for a traffic light, when I take off again there is a jolt like the pin has come forward a bit during the stop and is moving back against the jaws on acceleration. Is this normal? Or do I have something to worry about?

Also the hitch is pretty noisy when maneuvering. Lots of clunking. I noticed there is some play between the R20 base and the ISR rails. I can jiggle it slightly up and down. Also, there is some play between the R20 wheels and its base. Again, I can jiggle it up and down a bit. I assume that's the source of the clunking.

When I took delivery of the truck, with hitch installed, there was a plastic bag containing the teflon pad and 2 rubber pads shaped like rectangular donuts. I assume these are pads to go between the ISR and the R20. I also assumed these are just a couple of spares, but maybe they didn't put any pads on the ISR, or just installed 2 of them.

I don't know if I can check without lifting the whole hitch off the ISR with my front end loader. If I go to all that trouble, I may just lift it out completely and swap in a Blue Ox Super Ride and put the CURT on craigslist.

Any advice sincerely appreciated. We're leaving on a jaunt to Alaska soon and want to make sure I won't have any issues on the trip.

  • I used to have a Curt hitch and it was clanky and noisy enough that I got rid of it. Switched to a rail mount Andersen Ultimate and it's totally smooth and quiet. It weighs less than 40 lbs so it's super easy to install or remove.
  • I had the same hitch, Curt Q20. I've had it on a bolted down ISR frame, B&W turnover ball, and Ram factory puck system. It did the same thing as yours. I put a 5th Airborne pin box on the 5th and that dampened the up and down slop.
    I needed a lighter hitch after buying a cabover. I bought a PullRite SuperLite and stopped all that.
    I think all the clearances in the Curt, and probably most conventional hitches, have what is called "clearance stack up". Given certain circumstances, all the clearances in the hitch system add up to produce those unwanted results.
    PullRite SuperLite or Andersen will help a lot. I went with the SuperLight mostly because it was $100 less than Andersen. But it is also steel vs. the Andersen aluminum, if that makes a difference to you.
