Front Lower Ball Joint for 1999-2006 Chevrolet Silverado 1500 & More - Mevotech TTX TXK6539

Built for trucks that work hard, the Mevotech TTX ball joint TXK6539 is the front lower pivot between the control arm and the steering knuckle. It is a direct-fit replacement for many vehicles, among them the 1999-2006 Chevrolet Silverado 1500, the 1999-2006 GMC Sierra 1500 and the 2007 Chevrolet Silverado 1500 Classic. See the Buyer's Guide tab for the full list and engine-specific details.

Mevotech engineers its TTX line for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks. The line also uses Labor Saver designs, tools and hardware intended to make installation faster and easier.

• Maximum toughness: Patented sintered bearings are designed for longer-lasting performance.
• Larger sphere design: An application-specific ball stud system uses a larger sphere.
• Integri-Boot seal: The Integri-Boot design is built into the ball joint assembly to help lock out moisture and contaminants.
• Install hardware provided: A part-specific slotted castle nut and an easy-snap cotter pin secure the joint to the vehicle. Pre-applied nylok thread adhesive helps keep fasteners secure and resistant to vibration.
• Simple to service: A 180-degree and a 90-degree SAE grease fitting are included for routine lubrication.

A ball joint lets the knuckle pivot as you steer while the suspension moves over the road. Signs one may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, and play at the joint during inspection. If a worn front lower ball joint is behind those symptoms, TXK6539 replaces it.
