Functions
•  Secures the steering rack tie rod end in place
•  Helps maintain correct steering alignment and toe adjustment
•  Prevents the tie rod end from loosening during use
•  Supports accurate steering control and stable handling
•  Helps reduce steering play, vibration, or unwanted movement

Steering lock nuts are important safety-related fasteners and can lose locking strength after removal. They may also become corroded, rounded, seized, or damaged during steering and suspension repairs. Replacing the lock nut helps ensure the tie rod end remains securely fixed and correctly adjusted after service or wheel alignment.

When to replace
•  The steering rack tie rod end has been removed or replaced
•  The tie rod end has been adjusted during wheel alignment
•  The original nut is corroded, rounded, seized, or damaged
•  The nut no longer tightens or locks securely
•  There is play, looseness, or vibration in the steering linkage
•  Steering rack or front suspension repairs are being carried out
•  The nut has been removed and should not be reused
