Where it says 2R on the knuckle, what does that mean? My knuckle says 4R.Cory G.Jan 15, 2024
Best Answer:Hi Cory, I'm pleased to assist you. The "2R" and "4R" markings on the knuckle of a GM vehicle typically refer to the steering gear ratio. The "2R" indicates a steering gear ratio of 2:1, while the "4R" indicates a steering gear ratio of 4:1. This ratio is related to the number of turns of the steering wheel required to turn the wheels from lock to lock. A lower ratio, such as 2:1, means the steering is more responsive, requiring fewer turns of the steering wheel, while a higher ratio, such as 4:1, provides more leverage, requiring more turns of the steering wheel.
