What is a rear ball joint replacement?
A rear ball joint replacement services a small but important part of the rear suspension system of your vehicle.
Ball joints are composed of a round ball (fitted inside a socket) connected to a straight stud. The socket allows the ball to rotate free, while the stud attaches the joint to the control arm and/or steering knuckle. The vulnerable gap in the opening of the socket is protected by a rubber boot.
Over time, this rubber seal can fail, allowing dirt and grime to accumulate in the socket and wear out the ball joint. Worn ball joints cannot be repaired and must be replaced.
What are the symptoms of worn-out rear ball joints?
Here are the signs pointing to a bad rear ball joint in your vehicle:
Loose or more difficult handling
Involuntary steering towards the right or left (also known as “dog tracking”)
Clunking noises from the rear wheels
Key Takeaway A worn ball joint may cause steering issues, odd vibrations, and clunking sounds from the rear wheels.
What is the life expectancy of a ball joint?
The life expectancy of a ball joint is 70,000 to 150,000 miles. How long it’ll last depends on how often the driver performs maintenance, how much weight it supports, and whether it’s located in the rear or front wheel assembly. Generally, the lower ball joints wear out faster than the ones connected to the upper control arms, and the front ball joints fail sooner than the rear ones.
Is replacing rear ball joints a big job?
Changing ball joints
is a big job that requires basic equipment (including a jack, jack stands, and torque wrench), but plenty of mechanical experience. Suspension systems, brakes, and wheel assemblies are pretty complicated, and because they support so much weight, an incorrect installation could swiftly crack apart. We wouldn’t recommend the DIY approach unless you have detailed repair instructions and plenty of time.
