2003 and Newer Toyota 4Runner
Shop ECGS Toyota Clamshell Bushings for applicable 2003 and newer Toyota 4Runner 4WD applications. These 4Runner models use the Toyota 8-inch IFS front clamshell differential, where driver-side needle bearing wear can cause CV axle movement, front-end vibration, hum, growl, or gas-pedal buzz.
This category is for applicable selectable 4WD 4Runner models, not AWD or full-time/non-selectable 4WD applications. Choose the Complete Kit if you need the correct ECGS removal tool, installation tool, seal driver, and seal components.

2003 and Newer Toyota 4Runner Clamshell Bushing
This category covers ECGS Toyota 8-inch clamshell bushing products for many 2003 and newer Toyota 4Runner 4WD applications. These 4Runner models use a Toyota IFS front clamshell differential that can develop driver-side needle bearing wear and CV axle movement.
This bushing is for applicable selectable 4WD 4Runner applications, not AWD or full-time/non-selectable 4WD applications. If your 4Runner cannot shift between 2WD and 4HI/4LO, confirm fitment carefully before ordering.
Common symptoms include front-end vibration, gas-pedal buzz, growl, hum, roar, or a “whomp-whomp” noise around 30-50 mph. If the vibration disappears in 4HI and returns in 2WD, the ECGS PTFE clamshell bushing is the correct upgrade to consider.
The ECGS bushing replaces the factory driver-side needle bearing to better support the CV axle under side load. For DIY installation, choose the Complete Kit to get the correct bushing, removal tool, installation tool, seal driver, and seal components for the Toyota 8-inch clamshell differential.
