Not pulling a Jeep, but an F-150.had the same issues. Took the truck in for alignment and was told it was fine. Went thru the Roadmaster Tow bar and found no issues. Turns out that the slight movement between the receiver hitch, receiver drop down hitch, and tow bar, were causing the tires on the toad to not track straight going down the road. Put a Quiet Hitch device on at both the main receiver and where the tow bar attaches to the drop down hitch. Problem solved...zero issues in the last 10k of towing.
