If your Toyota Tacoma, Tundra, Sequoia, 4Runner, or FJ Cruiser has a subtle humming vibration in the gas pedal, especially at highway speeds, the cause is often a worn factory needle bearing inside the IFS clamshell differential. Over time, this bearing allows excess CV shaft movement, which leads to imbalance, noise, and premature wear. East Coast Gear Supply offers PTFE clamshell bushings that replace the problematic needle bearing, eliminate slop, support the shaft under load, and provide a permanent fix for the vibration.
Our PTFE bushings are precision engineered for Toyota differentials and use materials proven in aircraft landing gear for durability under side loads and high rotational speeds. Choose a standalone bushing or a complete installation kit with custom removal and install tools for a perfect fit. Whether your truck is stock or lifted, this upgrade is a proven solution trusted by Toyota dealers, off road shops, and owners around the world.
We offer bushings for Toyota 7.5 inch, 8 inch, and 9 inch IFS clamshell differentials found in 1986 and newer models, including 2005 and newer Tacoma, 2007 and newer Tundra, and compatible 4Runner and FJ Cruiser years. The result is smoother operation, longer differential life, and the end of that irritating vibration, all at a fraction of the cost of a new front differential. Browse the products below to find the right bushing for your model and start driving vibration free.

The Toyota clamshell differential design, used in many 1986+ Tacoma, Tundra, Sequoia, 4Runner, and FJ Cruiser models, relies on a needle bearing to support the driver’s side CV axle. In stock form, this bearing is prone to wear and excessive play, especially when subjected to off-road use, larger tires, or lifted suspension systems. The result is CV shaft movement inside the differential housing, leading to imbalance, humming or buzzing vibrations felt in the gas pedal, and over time, accelerated wear of internal differential components.
East Coast Gear Supply’s PTFE clamshell bushings are a direct replacement for the factory needle bearing. Made from polytetrafluoroethylene (PTFE) with a steel backing, these bushings are engineered to handle both high rotational speeds and significant side-load forces. PTFE is widely used in industrial machinery and aerospace applications, including aircraft landing gear, for its low-friction properties and exceptional durability under continuous load.
Our bushings are available for Toyota’s 7.5-inch, 8-inch, and 9-inch clamshell differentials, covering popular platforms like the 2005–present Tacoma, 2007–present Tundra, multiple 4Runner and Sequoia generations, and the FJ Cruiser. Each application-specific bushing is precision machined for a press-fit into the carrier housing, eliminating shaft slop and restoring proper support to the CV axle.
“Reduced axle play from .015 to .002 and zero play after 55,000 miles.” — brich999, TacomaWorld
“That night I drove two hours back to my house and it was smooth as butter, with zero vibrations.” — JoeCOVA, TacomaWorld
“Solved my problem 100% … Between 30–50 mph I’m getting that growl/vibe that goes away as soon as I switch to 4 hi.” — Mitch65, 4Runner Forum
For professional shops and DIY installers alike, we offer complete installation kits that include a custom bearing removal tool, depth-setting driver for proper bushing placement, and a seal driver to ensure the differential seal is installed squarely without damage. These tools simplify the process, reduce installation time, and ensure consistent results.
“The install went smooth and was really quite simple with the help of their special tools. … The whomp whomp whomp is gone now too, fantastic.” — kbahus, IH8MUD
“2006 2nd gen, have had one (driver’s side) for 75,000 miles, 3” lift. Cured the vibe and have no complaints.” — DDrewit, Reddit
Whether you are chasing down a persistent vibration, proactively upgrading during a suspension lift, or replacing a failed bearing before it causes more damage, the ECGS PTFE clamshell bushing is the permanent fix Toyota owners have trusted for over a decade.
