Hydraulic Suspension Bushings
Hydraulic suspension bushings were developed in response to specific customer desires: quieter and better-handling vehicles.
Suspension Bushing Logic
Compared to 20 years ago, suspensions have gone soft with larger-diameter bushings. During this time, both ride quality and handling have gotten better. Most modern bushings augment the geometry of the suspension. As the vehicle loads the suspension, movement in the bushings can change the toe, camber and caster so that the vehicle is more stable under braking, cornering and acceleration.

The tool, which is used without removing suspension parts from the vehicle, can significantly reduce time spent on bushing service.
Suspension Bushing Testing: When is a Bushing Bad?
There is no real maintenance schedule for a bushing beyond periodic inspection. While tie rod ends and ball joints might occasionally receive a little “thanks” for all their hard work in the form of a greasy treat, the bushing gets no such thanks. In fact, such a “treat” can mean death to a rubber bushing.
Tech Feature: Identifying Suspension Bushings that Cause Squeaks, Knocking Noises and Vibration Complaints
Worn or hardened suspension bushings can cause many mysterious squeaks, knocking noises and vibration complaints. Unfortunately, in their rush to sell ride control products like MacPherson struts, shock absorbers and springs, techs often forget to inspect and replace rubber suspension bushings, explains Import Specialist Contributor Gary Goms.
BALL JOINTS & BUSHINGS: Worn Components Take Their Toll on Advanced Suspension Technologies
Too often, shop owners and technicians alike assume that suspension systems haven’t changed much in the past 20 years. In reality, nothing could be farther from the truth because today’s import vehicle may incorporate a number of technologies that can be affected by worn steering and suspension components. To illustrate, we’re beginning to see electronic

Multi-Link Front Suspensions
Why do some suspensions have so many ball joints?
GM Rattle or Creak Noise From Front Suspension
The noise may be originating from the front lower control arm front bushing. Here’s how to correct it.
Curing Shock, Strut and Suspension Noise
As vehicles age, eliminating noise is Job 1. But ‘noise’ may mean different things to you and your customers.
