Description

Monroe shock absorbers for the front of the Toyota Avalon (part numbers 72307 and 72308) are specially crafted for the replacement market, addressing the expected wear in suspension and other components that naturally occurs after extensive kilometers of driving.

These shock absorbers operate akin to oil pumps: a piston affixed to the end of the piston rod moves within a pressure tube filled with hydraulic fluid. As the vehicle’s suspension moves up and down, hydraulic fluid is pushed through small holes (orifices) inside the piston. These orifices regulate the flow of fluid, slowing the piston’s movement and thereby damping the spring and suspension.

The resistance provided by shock absorbers depends on the speed of suspension movement and the size and number of orifices in the piston. They are velocity-sensitive hydraulic damping devices, meaning they adjust their resistance based on how quickly the suspension moves. This adaptive feature allows shock absorbers to respond to varying road conditions, which in turn reduces:

– Bounce
– Roll or sway
– Brake dive and acceleration squat

Shock absorbers operate through fluid displacement during both the compression and extension cycles. Typically, they provide more resistance during the extension cycle, managing the movement of the vehicle’s heavier sprung weight compared to the compression cycle, which handles the lighter unsprung weight. This dual-cycle operation enhances stability and comfort across diverse driving conditions.
