Tie Rod

Steering & Suspension

Description

The tie rods connect the centre link to the steering knuckle on cars with conventional suspension systems and recirculating ball steering gears. On cars with MacPherson strut suspension and rack-and pinion steering gears, the tie rods connect the end of the rack to the steering knuckle. A tie rod consists of an inner and an outer end.

Purpose

The tie rod transmits force from the steering centre link or the rack gear to the steering knuckle, causing the wheels to turn. The outer tie rod end connects with an adjusting sleeve, which allows the length of the tie rod to be adjustable. This adjustment is used to set a vehicle’s “toe”, a critical alignment angle.

Maintenance Tips/Suggestions

Your vehicle’s steering and suspension systems should be checked regularly, at least once a year along with a complete wheel alignment. A worn tie rod end can cause wandering, erratic steering, and excessive tire wear. If tie rod replacement is necessary, a wheel alignment is also required because tie rod replacement disturbs the toe setting. For best results, consult a qualified service technician for professional advice and service on your vehicle’s suspension and steering systems.
