How are Steering Idler Arm issues diagnosed?
When diagnosing a clunking or popping noise from the front end, the idler arm, as well as all other front end components will be checked for excess movement, and lack of firmness in the ball joints. If the idler arm displays excessive play, the ball joint on the idler arm is loose, or the technician can manipulate the centerlink to replicate the noise, the idler arm will be replaced. Also, a torn dust boot on the idler arm ball joint or a crack in the idler arm would call for replacement.
How are Steering Idler Arms replaced?
Replacing an idler arm takes only a few minutes with the proper tools. A ball joint separator will be used to separate the centerlink from the idler arm, and there will be few bolts that secure the idler arm to the chassis. Once removed, the new idler arm will be installed by securing the idler arm to the chassis and centerlink, torquing all fasteners, and aligning the wheels if necessary.
RepairPal Recommendations for Steering Idler Arm issues
If the idler arm is suspected of failure, all other ball joints should be inspected at the same time. The tie rod ends and pitman arm are under the same stress as the idler arm, so they may fail around the same time.
What to look out for when dealing with Steering Idler Arm issues
Though the centerlink looks like a strong place to place a jack, lifting a vehicle from the steering centerlink may cause failure or separation of the idler arm ball joint. If the idler arm ball joint fails, the vehicle could fall while lifting.
Can I replace the Steering Idler Arm myself?
With a good set of ball joint separators changing the idler arm is a very easy job. The average DIYer could inspect, diagnose, and repair a failed idler arm without difficulty as long as all safety precautions are exercised, and the proper tooling is used.
