Hydraulic suspension bushings were developed in response to specific customer desires: quieter and better-handling vehicles.
Potholes can be extremely damaging to vehicles—especially in terms of steering and suspension. Sometimes they’re simply unavoidable. If you notice issues with your vehicle after striking a pothole, the best thing the do is have an alignment check performed. Replacing affected parts can prevent the damage from spreading throughout the vehicle. Your vehicle’s steering and
The most important thing to remember is that as the suspension compresses, the alignment angles change.
If one suspension part is out of specification, it can cause noise or vibration in another.
Andrew Markel discusses the dreaded brake pull complaint, and focuses on three areas of the vehicle to check to diagnose this problem faster. Sponsored by Auto Value and Bumper to Bumper.
Most suspension system components pivot upon a rubber bushing that is compressed between an inner and outer metal sleeve. Because the compressed rubber bushing has no moving parts, it allows a maximum range of travel throughout a single plane without the frictional wear created in a conventional metal-to-metal bushing.
In this Tech Minute, Andrew Markel discusses suspension bushings and motor mounts, and the nature of the non-oil fluid that aids their function. Brought to you by Auto Value and Bumper to Bumper.
An alignment angle doesn’t change randomly. There is a cause-and-effect relationship between external and internal forces that can alter the geometry of a vehicle’s suspension. Having the alignment reading for only one angle on one corner is just like knowing the temperature without knowing if there is a tornado outside. Just making adjustments and not asking why the adjustments were needed can lead to a comeback. Knowing why the adjustment is required is critical to performing the total alignment.
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.
If you look at some of the premium European luxury cars and SUVs from 2007-‘10, you will find some game-changing engineering when it comes to the suspension and ride control components.
The expansion includes new ball joints, bushings, control arms, drag/center links, pitman/idler arms, sway bar links and tie rods for more than 200 million vehicles on U.S. roads today.
2011-’14 Compass/Patriot 2011-’12 Caliber Condition: The driver may describe creaking or squeaking noises coming from the front suspension. The noise is typically more noticeable during cold temperatures below 40°F. The noise may go away when the temperature warms up. Cause: The front lower rear control arm bushing is making the noise. Remedy: Lubricating the bushing
