Keep the steering tight and responsive with the MOOG CHASSIS tie rod end ES800421, a direct-fit front left outer steering tie rod end for heavy-duty applications. It drops into the front left outer position on the 2003-2009 Chevrolet C4500, C5500, C6500 and C7500 Kodiak, the 2003-2009 GMC C4500, C5500 and C7500 Topkick, the 2004-2009 GMC C6500 Topkick, the 2004-2017 Blue Bird Vision School Bus, and the 2005-2010 Hino 145, 165 and 185 — see the Buyer's Guide tab for engine-level detail and the full list.
- Greaseable socket: Lets fresh lubricant flush out contaminants to help reduce corrosion and wear.
- Pressed-in cover plate: Patented design seals out debris and minimizes looseness, helping reduce bearing wear for longer life.
- Gusher Bearing: Problem Solver metal-to-metal design lets grease flow through the bearing surface for reduced friction.
- Belleville preload washer: Helps keep the bearing package tight as the bearings wear.
Ball studs are heat treated to match or exceed OE requirements to improve fatigue strength, and precision tolerances make for a straightforward installation and alignment. If a worn tie rod end is the cause of loose steering, uneven tire wear, or a wandering feel, this replaces the failed unit.
