There`s no denying that it`s very important to replace your ball joints when needed. However, it`s worth noting that doing that doesn`t necessarily mean you need an alignment. The only time you need one after replacing the ball joints is if the previous alignment was performed when ball joints were not in good shape.
Steering — Worn ball joints can affect your vehicle`s steering, usually making the steering sloppy or stiff depending on how the ball joint is wearing.
A lower ball joint replacement on that vehicle shouldn`t need an alignment afterwards, unless the current alignment was compensating for wear. In which case new lower ball joints might throw it off.
The lower ball joints are attached to the control arm and are primarily responsible for transferring loads from front tires to the axle. They also help in providing stability and accuracy when turning corners.
Why replace ball joints? Ball joints deteriorate if dirt, grit and impurities get inside or grease escapes, leading to a lack of lubrication. Added to this, rusting and general wear and tear also damage these suspension parts.
Test fit the new ball joint by hand to check the fit of the stud taper to the knuckle. The stud should seat firmly without rocking, and only the threads of the stud should extend through the steering knuckle.
Clunking, Rattling Noise
If the rattling is more pronounced as you go over bumps and dips in the road, then it`s almost certainly coming from a suspension problem. Over time, the sound may get louder as the ball joint wears further and becomes even looser as you drive.
Ball joints typically last 70,000 to 150,000 miles depending on their usage and road conditions. Clunking noises, poor handling, pulling, and abnormal wearing of your tires are all signs of a worn ball joint. If you see uneven tread wear patterns on your tire, you should have your ball joints checked.
Directional type ball joints must be installed in the proper orientation to function correctly. These ball joints are designed to have a certain range of motion. Generally, the swing angle of the ball joint stud travels inboard to outboard. Directional type ball joints feature an index or alignment mark on the flange.
Because the ball joint is a “directional” type (Figure 5), the swing angle of the ball joint stud is limited in its range of motion (inboard-to-outboard). Incorrect installation (i.e., orientation of the housing) could cause damage to the ball joint resulting in premature failure.
Ball joints typically cannot be replaced separately, so the entire control arm needs to be replaced. The ball joints are critical to vehicle alignment, so these control arms should also be replaced in pairs.
For driver safety, MOOG recommends that a `press-in` ball joint is only replaced on one occasion and that any subsequent repair should use a fully assembled wishbone arm.
Many ball joints may have an initial torque spec as low as 15-30 ft./lbs. and torque angles are between 140º and 225º. Never guess or try to use your calibrated elbow. Always look up the spec and use a torque wrench.
After replacing the ball joints on one or both sides you will need to get an alignment done. If you only replace one side, get the alignment done, and need to replace the other side in a month, another alignment will need to be done.
Ball joints typically cannot be replaced separately, so the entire control arm needs to be replaced. The ball joints are critical to vehicle alignment, so these control arms should also be replaced in pairs.
A ball joint replacement will typically take around one hour, but it can take less or more time depending on several factors.

A ball joints is made to fit tightly into its steel casing; excessive wear will allow for more room for the ball to move in the socket, which can affect wheel alignment, tire wear, and suspension noise.
