2PCS Front Outer Tie Rod Ends ES3691 LH & RH, Tie Rod End Kit Fit for Ford F-150 Lincoln Mark LT 2004-2008

• Vehicle Application — Precision-Matched Outer Tie Rod Ends: Front outer tie rod ends Kit Fit for 2004–2008 Ford F-150; 2006–2008 Lincoln Mark LT. Direct replacement for OE interchange number: ES3691. Verify vehicle VIN, platform designation, and steering system type prior to purchase
• Material Specification — AISI 1045 Medium-Carbon Steel Construction: Tie rod end housings forged from AISI 1045 steel, induction heat-treated to HRC 35–45 hardness range for optimized fatigue resistance and impact durability. Ball studs precision-machined to SAE J498 standards, pre-greased with lithium-based NLGI Grade 2 lubricant
• Functional Restoration — Steering Geometry Compliance: Worn outer tie rod ends compromise toe angle alignment, resulting in steering wheel oscillation, asymmetric tire wear patterns, and degraded directional stability. Replacement of both driver (LH) and passenger (RH) side tie rod ends restores factory steering geometry, eliminates rack-end lash, and ensures consistent tie rod axial load distribution across the steering linkage
• Installation Protocol — Service-Ready Configuration: Kit comprises 2x front outer tie rod ends with LH/RH thread orientation pre-configured. Torque tie rod end nuts to manufacturer specification; mandatory four-wheel alignment post-installation to correct toe settings and prevent premature tire degradation
• Quality Assurance — 12-Month Replacement Coverage: Components manufactured to meet or exceed SAE J490 and ISO 15529 steering linkage performance standards. One-year limited warranty against material defects and workmanship
