Description
Volkswagen Jetta front left ball joint
Achieve dependable front left suspension performance in your Volkswagen Jetta with this ball joint assembly, tailored for the lower control arm on the driver’s side across MK4 to MK7 models. It eliminates looseness that causes handling issues on bumpy Kenyan roads, supporting precise steering and up to 100,000 km longevity with regular greasing. The robust design includes a protective boot to seal out debris, offering OEM-equivalent strength for urban or highway driving. Includes castle nut, cotter pin, and lock plate for secure mounting; confirm left-side fit via VIN to match engine (e.g., 1.8T, 2.0 TDI) and avoid mismatches in sport trims. Pair with bushing inspection for full refresh; professional torque prevents over-stressing the stud.
