How to Replace the Springs in a Chevy Impalaby Contributor
The Chevy Impala is truly a classic and one of Chevy's most popular models since the 1960s. Impala's various model years feature coil springs. Changing the Impala's springs requires the standard tools. SS (Super Sport) and other sporty Chevy Impalas feature heavy duty suspension systems and will require high performance springs from Chevy or another reputable Chevy Impala parts dealer.
Raise the Impala, and block the wheels with jack stands before removing the wheels.
Remove the strut assembly from the Impala. If you are servicing an older model Impala, you may need to use some elbow grease and WD40 to loosen the strut assembly.
Mount the strut assembly in the strut compressor. The strut compressor holds the strut steady while removing the spring and other components. Strut compressors have holes designed to hold the struts from various models. Install locking pins and tighten the nuts before disassembling the strut. Use great caution at this point, as the spring coil holds a great deal of energy, and should be removed carefully to avoid injury.
Use the bottom locking pin only to install the spring over the damper. Chevy Impala SS models require heavy duty springs.
Install the spring seat on top of the spring. Make sure the seat is facing the center of the spindle on the strut assembly, before installing the guide rod and tightening the rear and front nuts om the Impala's struts.
Remove the strut from the compressor and install on the Impala. Repeat the procedure for each strut. If your model Impala is an older model or the suspension has been modified for shows etc., this procedure may vary depending upon the age of the vehicle and extent of modification.
Lower the vehicle and tighten all nuts and bolts. Take the time to double check all components that were moved aside, replaced, or reinstalled before taking away the jack stands.
- Take the pressure off the springs before disassembling. This is potentially very dangerous as the springs carry a great deal of force which is expended when their restraints are released.
