2020 Model. Pulling with 2021 Ram 2500 Diesel. Have 3000 miles plus with no issues.

Now at speeds as low as 30 mph can hit a bump and side to side rocking translates into trailer sway. Worse going uphill. Had a trip this weekend and put two new tires on the rear axle. My tire shop only had two.

Is this axles out of alignment?? Shocks on the truck? ( 30k miles on truck).

I pulled the tires off and bearings are good. Measured and axles are same distance between tires. Did not measure to the pin.

Tread is still good on front axle. And was good on the two that were replaced. Wear is even. Could not detect that they were out of round when jacked up and spun the wheels.

Any help is welcome. Have years experience of towing trailers. The sway is dangerous. Not a slight annoyance. Thanks.

Looks like you have checked out the trailer, but what about the truck? On a vehicle as new as yours with few miles, it would seem to be unlikely that there would be a suspension problem. But ya never know. That would be my next step.

If you can find an empty parking lot somewhere, maybe you can put the truck through some slalom type turns at a speed that would challenge the suspension and see what happens.

Have you scaled your rig? Maybe you have too much weight to the rear.

That’s all I got…………..

Not a dumb question. We just checked them and all tight.

Measured from axle to the pin and they are the same distance.

Dumb question maybe, but are your hitch bolts tight?
