1998-2011 Ford Ranger | Rear Leaf Spring Bushings
Polyurethane rear leaf spring bushings from energy suspension will replace soft rubber bushings that can become worn or damaged with normal driving, leaving a lot of play in the rear suspension of your Ranger. To tighten up the rear leaf springs upgrading to poly bushings is a cost effective option that replaces a short-lifespan part with a much longer-lifespan one.
Bad Original Rubber Bushings
The rear leaf springs are responsible for cushioning the bounce in the rear axle but they can also have an effect on alignment when the bushings that connect the leaf springs to the chassis are loose. This can cause issues with straight line tracking and the thrust angle of your truck. Rubber bushings provide a smooth ride but they do this by flexing with every movement of the rear suspension and they will begin to change shape and leave a permeant gap which means play in the rear leaf springs.
Stable Wheel Alignment
Polyurethane bushings mean a firmer connection between the leaf springs and the frame which can cause a little rougher ride but means that the rear leaf spring stay where they are supposed to. This keeps the rear axle in alignment so the thrust angle is not fighting against where you want to steer and can result in more even tire wear and fewer replacements. Besides the alignment benefits polyurethane bushings have a lifespan around five times longer than rubber bushings, so if you are replacing the originals then using poly is a good investment.
