Moog K5208E Front Upper Suspension Ball Joint Problem Solver

The Moog K5208E is a front upper suspension ball joint engineered as a direct OE replacement for select General Motors vehicles. As part of Moog's renowned Problem Solver line, this ball joint incorporates proven design improvements that deliver enhanced durability, reduced friction, and long service life compared to standard replacements.

At the core of the K5208E is Moog's Problem Solver Gusher Bearing — a metal-to-metal design that allows grease to flow through the bearing surface to the stud, significantly reducing friction while improving strength and stability. The patented pressed-in cover plate seals out debris and minimizes axial and radial looseness, restoring like-new steering feel and extending component life.

Key Features:

• Heat-Treated Ball Stud — Engineered to meet or exceed OE specifications, improving fatigue strength and inhibiting premature failure
• Powdered Metal Gusher Bearing — Channels grease through the bearing to the stud for reduced friction and enhanced durability
• Patented Cover Plate Design — Tighter tolerances versus traditional designs; seals out contaminants and minimizes looseness
• Greaseable Socket — Allows fresh lubricant to flush out contaminants, reducing corrosion and extending service life
• Belleville Preload Washer — Absorbs impact and keeps the bearing package tight as components wear
• Flange-Style Sealed Boot with Grease-Relief Valve — Protects against road contaminants and maintains a serviceable sealed environment
• Full-Ball Metal Stud — Provides 360 degrees of smooth, consistent rotational movement for more responsive steering
