🔧 Ball Joint Replacement - Front Suspension Repair

This repair covers the front lower ball joints on your Corolla. The ball joint connects the lower control arm to the steering knuckle, so wear here can cause clunks, loose steering, and uneven tire wear. If the joint is badly worn or riveted in place, replacing the full lower control arm may be the better fix.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• Work on a flat surface and support the car with jack stands before removing any suspension parts.
• Use wheel chocks on the rear wheels.
• Keep hands clear of the knuckle and control arm while separating the joint. It can move suddenly.
• If the lower ball joint uses a cotter pin, replace it with a new one. Never reuse it.
• Do not let the brake hose hang unsupported while the knuckle is moved aside.
• A wheel alignment is required after this repair.
