Introduction
The steering ball joint is the mechanical part that allows the wheels to turn, but also, in association with the suspension ball joints, to absorb certain shocks. This part is the link between the steering rod and the wheel.
This operation is carried out here on an Alfa Romeo 147 phase 1 Twin Spark 120hp . However, it is similar to other vehicles.
Parts
-
-
Apply the handbrake, then jack up the front of the car and place it on axle stands. Remove the front wheel on the side where the vehicle is being serviced.
-
-
-
Outer tie rod ends.
-
Tie rod end locking nut.
-
Steering rod (connects the steering rack and the tie rod ball joint).
-
Hub carrier pivot.
-
The lock nut allows the parallelism to be adjusted, so it must never leave its original position.
-
-
-
To maintain the position of the locknut, place a mark with tape. For added safety, do not hesitate to take a measurement using a caliper.
-
Check that the new part is identical in every way to the original, otherwise the parallelism will be modified.
-
-
-
Loosen the locknut by half a turn only to maintain its original position as much as possible. Loosen it in a clockwise direction.
-
Remove the nut securing the tie rod ball joint to the hub carrier pivot, then extract the ball joint cone from the pivot using a universal ball joint remover (a hammer can also do the trick).
-
Then completely unscrew the ball joint at the end of the steering rod, counting the exact number of turns to achieve this.
-
Don't hesitate on WD40.
-
-
-
Clean the steering rod threads thoroughly.
-
Screw the ball joint into the end of the steering rod, observing the same number of turns noted during removal.
-
Reconnect the ball joint cone to the hub carrier pivot then reinstall the fixing nut.
-
If rotation occurs when tightening the ball joint axle nut, block it by exerting pressure below the ball joint using a jack.
-
Tighten the locknut counterclockwise.
-
Put the wheel back on and then bring the car back to the ground.
-
If there is a change in the vehicle's behavior after this operation or if there is any doubt, have the alignment done by a professional.

Good precise advice. We can therefore avoid parallelism by a professional when we have taken good precautions during assembly and disassembly.
