MOOG K90255 Front Upper Suspension Ball Joint for Toyota Tundra

In this review the MOOG K90255 front upper suspension ball joint is judged as a practical replacement part for owners of late 1990s and early 2000s Toyota trucks and SUVs who want dependable steering restoration without surprises. The single biggest reason to buy is its problem-solving design: a metal-to-metal gusher bearing and a greaseable socket that together promote long life and keep lubrication flowing where it matters. For anyone replacing a worn upper ball joint on compatible Toyota 4Runner, Tundra, Sequoia or Tacoma models this unit delivers a straightforward install and clear durability improvements over basic OE-style parts.

Key Features

• Vehicle Compatibility: Fits a broad range of Toyota 4Runner, Tundra, Sequoia and Tacoma model years to simplify parts selection when your vehicle matches the listed years.
• Gusher Bearing Design: Metal-to-metal bearing lets grease flow through the bearing surface which reduces friction and supports longer bearing life under load.
• Greaseable Socket: A grease zerk allows periodic lubrication to flush contaminants and inhibit rust, extending service life when maintained.
• Heat-Processed Ball Studs: Studs are treated to meet or exceed original equipment strength for improved fatigue resistance and reduced premature failure risk.
• Press-Fit Cover Plate: A pressed-in seal keeps dirt and moisture out of the bearing package to minimize looseness and wear over time.
• Belleville Preload Washer: The washer maintains preload on the bearing stack so the joint stays tight as parts wear, preserving steering feel.

Who It's For

This ball joint is geared toward DIY mechanics and professional technicians working on 1996-2002 Toyota 4Runner, 2000-2006 Toyota Tundra, 2001-2007 Toyota Sequoia and various 1995-2004 Tacoma models who need a direct-replacement upper front joint that balances ease of installation with durable components. It is a good option if you value a greaseable design for ongoing maintenance and a design intended to reduce bearing friction.

Those who should look elsewhere include owners of vehicles outside the listed year ranges or shoppers who require an application-specific part verified by vehicle trim, engine, and fitment notes before purchase. Also consider alternative premium or lifetime-warranty options if a torn boot history is a major concern for your intended use.
