Subaru Front Lower Control Arm Replacement Cost
Replacement of the front lower suspension control arms due to bushing failure or ball joint wear.
Why this fails
Subaru use a 'horizontal' rear bushing design (especially on the BP/SH/SJ chassis) that carries the brunt of braking forces; over time, the rubber tears or the fluid inside the dampening bushing leaks out. High-mileage EJ and FA/FB engine vehicles are also prone to oil leaks from the cam carriers or oil filters dripping onto the rubber, accelerating degradation.
What the job involves
- Lifting the vehicle and removing front wheels.
- Disconnecting the stabilizer bar end links and ball joint pinch bolts.
- Removing the large rear 'liquid-filled' bushing bolt and front pivot bolt.
- Installing the new control arm assembly and hand-starting all Grade 10.9 hardware.
- Torquing all fasteners to spec while the suspension is under 'curb weight' load (critical for bushing longevity).
- Performing a professional four-wheel alignment to reset toe and camber.
If you delay this repair
Ignoring torn bushings leads to rapid inner-tire wear, 'darting' under braking, and eventually, catastrophic ball joint failure which can cause the wheel to fold inward, resulting in a total loss of steering.
Save money
- • Buy complete control arm assemblies (with bushings/ball joints pre-installed) to save on labor costs compared to pressing out old bushings.
- • Check for torn CV axles while the arm is removed; combining these jobs eliminates redundant labor.
- • Opt for reputable aftermarket brands like Moog or Mevotech if the vehicle is over 10 years old.
