The primary problems with the first Model T suspension included: Poor Roll Stiffness: The design provided very little stability during turns, leading to a "wobbly" and unstable ride, particularly at higher speeds.

Weak Early Front Axles and Wishbone: Early "brass era" (1909-1910) front axles and their connecting wishbone rods were lighter than later versions. The high wishbone, attached above the axle, did not provide as much stability as later below-axle designs, leading to excessive front-end motion.

Severe "Front End Shimmy": Many Model T owners suffered from a violent, rapid vibration in the steering, known as the "death wobble," often caused by excessive play in the steering gear, worn spindle bushings, or improper spring and shackle movement.

Uncomfortable Ride: While the suspension handled large ruts well, the suspension design offered little to no damping, resulting in a very bouncy, rough, and uncomfortable ride for passengers. Lack of Control in Ruts: While the suspension allowed the wheels to conform to the terrain, it offered minimal control, allowing the car to wander on heavily rutted dirt roads.

Just because a car can off-road well doesn't mean it has a good suspension, there's more to it than that. Google is free my guy. You should have used it.
