Ball joints are an important part of a vehicle’s suspension system, connecting the steering and suspension components to the wheel and axle assembly. They are responsible for allowing the wheels of the vehicle to move up and down in order to absorb road shocks and bumps, while also allowing the wheels to turn left and right in order to steer the vehicle. As such, it is important to ensure that ball joints remain in good condition and have the right amount of play in order to ensure that the vehicle is operating safely and efficiently.
How much ball joint play is acceptable?
The amount of play in the ball joint is measured in degrees of angularity, or arc, and should generally be no more than 1 degree of play. More than this amount can indicate that the ball joint is worn or damaged, in which case it will need to be replaced. If the amount of play is less than 1 degree, then the ball joint is considered to be in good condition and does not need to be replaced.
It is important to note that the amount of play in the ball joints can vary depending on the type of car and the type of suspension system. For example, vehicles with a strut suspension system may have more play in the ball joint than those with a MacPherson strut suspension system. Similarly, vehicles with a solid axle suspension system may have less play in the ball joint than those with an independent suspension system.
In general, it is best to consult with a qualified mechanic in order to determine the specific amount of play that is considered acceptable for the type of vehicle and suspension system you have. This will help ensure that the ball joint is in good condition and that the vehicle is operating at its best.
In addition, regular inspections should be performed to check that the ball joint play is within acceptable levels. This can be done by jacking up the vehicle and using a pry bar to move the wheel and axle assembly in order to check the amount of play. If the amount of play is more than 1 degree, then the ball joint should be replaced.
How much vertical movement in a ball joint is too much?
Vertical movement in a ball joint is generally considered to be too much when it exceeds the manufacturer’s specifications. This is because too much vertical movement can cause excessive wear on the joint and its surrounding components. Too much vertical movement can also indicate underlying problems, such as worn-out parts or an imbalance in the suspension system. In general, if the vertical movement in a ball joint exceeds 1/8 of an inch, it is likely too much. If a ball joint is exhibiting too much vertical movement, it should be inspected or replaced as soon as possible to ensure the safety of the vehicle.
How to tell if a wheel bearing or ball joint is bad
1. Listen for a grinding or roaring noise when you turn the wheel. If you hear these sounds, it may be a sign that your wheel bearing or ball joint is bad.
2. Check for any play in the wheel. If the wheel has too much play, it could be a sign of a bad wheel bearing or ball joint.
3. Look for any visible rust, cracks, or other signs of wear. If you see any of these signs, it could be an indication that you have a bad wheel bearing or ball joint.
4. Check the tire treads. If there is uneven wear or patches of bald spots, it could be a sign of a bad wheel bearing or ball joint.
5. Look for any leaking fluid. If you notice a leak, you may have a bad wheel bearing or ball joint.
6. Have your car inspected by a professional. A professional mechanic can check for any signs of a bad wheel bearing or ball joint.
How to check ball joints with a pry bar?
- Lift the vehicle and support it with jack stands. Remove the wheel and tire assembly.
- Visually inspect the ball joint for any signs of cracks, leaks, or wear and tear.
- Use a pry bar to gently pry the upper control arm and the lower control arm in opposite directions.
- Inspect the ball joint for any movement. If the ball joint moves more than 1/8th of an inch then it needs to be replaced.
- Locate the castle nut at the top of the ball joint. Using a socket wrench and a tensioner, hold the castle nut in place while you loosen the nut.
- Remove the castle nut and the tensioner.
- Using a pry bar, gently pry the ball joint from the control arm.
- Inspect the ball joint for any signs of wear and tear.
- If the ball joint is worn, replace it with a new one.
- Reassemble the ball joint and torque the castle nut to the specified torque rating.

How much ball joint play is acceptable? – Conclusion
In conclusion, the amount of ball joint play should generally be no more than 1 degree of angularity in order to ensure that the vehicle is operating safely and efficiently. It is important to consult with a qualified mechanic in order to determine the exact amount of play that is considered acceptable for the type of vehicle and suspension system you have, as this can vary depending on the type of car and suspension system. Regular inspections should also be performed in order to check that the ball joint play is within acceptable levels. If the play is more than 1 degree, then the ball joint should be replaced in order to ensure the safety and proper operation of the vehicle.
