NOPE.
Poly Bushings need lubrication almost yearly or they will squeek. First pic is poly, second one is rubber.
There are two broad categories of bushings: those that rotate and those than remain stationary. The rotational bushings should be rubber. The sway bar bushings are in the rotational category!
Rubber bushings are always appropriate. Polyurethane should be kept to bushings that do not move. Due to rubber's unique characteristics, it may feel quieter and smoother than polyurethane. This is a natural phenomena and does not necessarily mean that rubber has worse performance characteristics.

poly bushing are great if you want to have a stiff suspension and plan to drive the car hard. The down side is the poly bushings are hard and do not absorb road shock like rubber bushings. That means the shock is transmitted through the suspension to the body. Poly bushings also have a tendency to squeak.
In sway bar mount applications, most squeaking comes from not cleaning the sway bar prior to installing the bushings and not using our “squeak proof” grease!
The original rubber bushing or mount was fairly soft which helped to attenuate noise and vibration that is generated by the tires and road surface. Increasing the hardness of the bushing either with harder rubber, urethane or even bronze, will allow more transmission of noise and vibration. Some manufacturers formulate the hardness and design to reduce this effect. A softer urethane bushing allows the vehicle to perform better without the harshness, even over the same hardness rubber piece.
Guess it depends on what you got and how you installed them.

Good luck.

shocks on mazda
I have a 2010 Mazda 5 and have had many issues with back shocks but it's not the shocks themselves it's the upper back mount that keeps breaking it's a 23.00 part at hole works and decently easy to fix...and $26.00 at auto zone
