Tie end components connect steering rack or gearbox output to steering knuckles, facilitating directional control. These assemblies—including inner and outer tie rod ends—are critical parts of the front steering system in most vehicles. Ball joints within the tie end allow for angular movement, accommodating suspension travel and steering input. Construction typically involves forged steel or aluminum bodies with hardened ball studs, ensuring durability under load. Boot kits are commonly supplied to maintain lubrication and protect against contamination, extending service life. Proper torqueing of lock nuts is essential for safe and accurate steering alignment.
