SUMO Toyota 8.0" Front Differential Complete Bushing Kit
Driver Side | Needle Bearing Replacement + Premium Installation Tools
The SUMO Complete 8.0" Differential Bushing Kit gives you everything needed to upgrade the driver-side CV axle support in Toyota 8.0" front clamshell differentials.
This all-in-one solution includes the engineered bushing, precision install tooling, a protective carry case, and step-by-step installation support — making it ideal for shops, builders, and performance enthusiasts alike.
By replacing the original needle bearing with a robust PTFE-lined bushing and providing a dedicated tool set, this kit improves differential stability, reduces vibration and shaft movement, and delivers a smooth, serviceable installation experience.
What’s Included
✔ SUMO 8.0" Differential CV Axle Bushing
A full-length, sintered PTFE support bushing designed to replace the original needle bearing.
✔ Upgraded Installation & Removal Tools
Purpose-built fixtures and drivers to make removal of the factory needle bearing and installation of the SUMO bushing more consistent, controlled, and repeatable.
✔ Durable Protective Case
Keeps all tooling, drivers, and components organized and protected between uses — ideal for mobile techs and busy shops.
✔ Detailed Written Instructions (PDF)
Clear, photo-illustrated steps to help ensure proper removal, installation, and best practices — reduces guesswork and installation time.
Engineering & Performance Highlights
- Metal-backed sintered bushing with PTFE bearing surface
- Full contact surface for improved support over the original needle design
- Engineered to reduce axle vibration, shaft float, and driveline noise
- Designed to withstand real-world use — daily driving, off-road, towing, and high-load conditions
- Includes premium tooling for a professional installation experience
Vehicle Compatibility
This kit fits Toyota vehicles equipped with the 8.0" front clamshell differential, including:
- Toyota Pickup (8.0" models)
- Toyota T100
- Toyota Tacoma
- Toyota Tundra (8.0" chassis)
- Toyota 4Runner (8.0" variants)
Driver-side only.
Installation Guidance
The SUMO bushing is intentionally longer than the factory needle bearing to provide better axle support. Some differential carriers contain an internal bore shoulder or ridge.
- Target installed height: 0.030"–0.065" above the carrier bore
- Do not force the bushing past an internal stop — doing so can deform the part and interfere with axle fitment
- Install using steady, controlled force with included tools
- Verify seating height before final assembly
This method ensures the bushing is installed correctly without risking damage to the bushing or the differential housing.
Notes & Fitment Cautions
- Not compatible with bolt-in locker assemblies or integrated axle support lockers
- Not intended for manual hub carrier applications
- Designed specifically for Toyota 8.0" clamshell differentials with standard CV configurations
Why This Kit Matters
The original needle bearing design in Toyota clamshell differentials provides limited contact and support for the CV axle shaft. In many vehicles, especially those with higher mileage, lifted suspension, or frequent heavy use, the OE bearing wears prematurely — resulting in vibration, noise, and shaft movement.
The SUMO 8.0" bushing kit:
- Provides higher contact surface area
- Improves axial support
- Reduces dynamic vibration
- Extends service life
The addition of custom tooling and a dedicated carrying case makes this kit a professional-grade solution for both field and shop installations.
Recommended Pairings
For comprehensive Toyota drivetrain improvement and durability, this kit pairs exceptionally well with the following SUMO Toyota sleeve kits:
- TSK44
- TSK45
- TSK46
- TSK48
- TSK49
Together, these upgrades address both the differential support and internal transmission wear points for a smoother, more reliable drivetrain.
