What is a "tie rod"?

Post by Mozi »

I was reading some articles and it says that you can break a tie rod if you are not going straight and hit something hard. It says to better have spare tie rods with you. What the hell are those thingies?

Description: The tie rods connect the center 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 center 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.

Hummer's are IFS , thats a solid axle...? Dont mean to be a PITA , jst bugging me trying to find out what car thats from... :roll:

u can also check the conditions of the bushings on the tie-rod ends.
when its time for a change , u hear a *clunk clunk* sound when u turn the steering wheel quickly back and forth.
simple job changing them out , but easier done when the wheels havent got any load on them...and yeah , u gotta get the wheels aligned after.
wouldnt bother keeping them as spares unless u run really big tires on rocks (sand is more forgiving)...personal opinion ofcourse.

When u get a steering alignment done , they adjust the tie rods.they're the things that keep your wheels connected to the steering...in basic terms.

But now after your post.. mmmmm... maybe it's a hammer tie rod :D

Interesting safety point about tie rods is that the majority of them are made from hollow steel pipe.

On our beefed up Defenders we use another type of tie rod called a SUMO bar. Solid steel and very strong.

Back to the hollow ones which are nothing more than a steel tube with ball joints or rose joints at each end.
The ball joints are secured by a pinch bolt. This works by compressing a slot cut in the tie rod.
Should you ever go through water crossings...water gets into this slot and rusts the tie rod from the inside. The rod may look beautiful and painted black on the outside...but the water trapped inside...(salty water is even worse) is slowly rotting the metal without being seen.
Before you know it.....crack, the rod breaks and you have no steering!

Cures for this are simple. Remove the rod and inject the rod with a rust proofing paint or underseal/Waxoil etc. Be sure to align the rods ends properly when re-fitting or even better get the wheels re-aligned by a proffesional.

LandRover owners are very well aware of this trick because it's been hi-lighted in many of the Rover mags over the years. A few people have even died because of it!
