I looking for some help on my 2024 Tacoma Sport. When buying the Sport trim model it was explained to me that the sport is just a glorified SR5 with some fancy sporty looking bits. But 5000 miles in, this truck is bouncing me to death. It can be super smooth at times but it's the worst on cement...
How's it going trying to solve your issue with the vibration? I have the same vibration with my Sport. I had the tires balanced 3 times, then replaced the tires for a new set and the truck is still vibrating above 50 mph.
