Subaru Xv Crosstrek Control Arm & Ball Joint Assemblys

Subaru Xv Crosstrek Control arm & ball joint assemblys

Control arm and ball joint assemblies for the Subaru Xv Crosstrek start at low prices. We stock multiple units from top OE-quality brands. This combined assembly connects the wheel hub to the vehicle's frame, allowing the wheel to move up and down while staying aligned. When it wears out, the ball joint can separate — causing sudden, dangerous loss of steering control.

Signs your Subaru Xv Crosstrek needs a new control arm and ball joint assembly

  • Clunking or knocking noise from the front suspension when hitting bumps or turning
  • Steering wheel pulls noticeably to one side on a flat, straight road
  • Front tires show uneven or accelerated wear on the inner or outer edge
  • Vehicle wanders or feels loose at highway speeds despite a straight road
  • Visible play or slop in the wheel when rocked at the 12 and 6 o'clock positions with the vehicle lifted
  • Front end vibration that worsens during acceleration or light braking

Which control arm and ball joint assembly should you buy for your Subaru Xv Crosstrek?

The main decision is whether to buy an OE-replacement assembly, a heavy-duty/greaseable upgrade, or a position-specific unit (upper vs. lower, driver vs. passenger). Most front suspensions use lower control arms with integrated ball joints, though some Subaru Xv Crosstrek configurations also require an upper arm. Matching the correct side and grade to your driving conditions matters more than brand alone.

After safely lifting and supporting the Subaru Xv Crosstrek and removing the wheel, disconnect the ball joint taper from the steering knuckle using a separator tool, then unbolt the control arm from the frame mounts. Install the new assembly in reverse order, hand-tightening all fasteners before lowering the vehicle to ride height, then torque to specification with the suspension loaded. Always follow up with a professional four-wheel alignment before returning the vehicle to normal use.

Frequently asked questions

How much does it cost to replace control arm and ball joint assemblies on a Subaru Xv Crosstrek?
Parts start at low prices for a single assembly on the Subaru Xv Crosstrek. Most owners replace both sides at once, so budget for two units plus alignment. Professional labor typically adds one to two hours of shop time per side. Doing it yourself with basic tools keeps total cost close to the parts price alone.
Can I replace just the ball joint instead of the whole control arm assembly on my Subaru Xv Crosstrek?
On many Subaru Xv Crosstrek applications the ball joint is pressed into the control arm and can be replaced separately, but it requires a press and precise fitment. Buying the complete assembly is usually faster, often similarly priced, and eliminates the risk of improper press-fit installation. If the control arm bushings also show wear, the assembly replacement makes even more sense.
Is it safe to drive a Subaru Xv Crosstrek with a worn or failing ball joint?
No. A worn ball joint is one of the most serious suspension failures you can ignore. If the stud separates from the socket while driving, the wheel can fold under the vehicle without warning, causing an immediate loss of steering and braking. Clunking, pulling, or play in the wheel should be inspected and repaired before the vehicle is driven further.
Do I need a wheel alignment after replacing control arm and ball joint assemblies on a Subaru Xv Crosstrek?
Yes, always. Replacing a control arm changes the pivot point of the suspension, which directly affects camber, caster, and toe alignment. Driving without a post-installation alignment will cause rapid, uneven tire wear and unpredictable steering. Budget for a four-wheel alignment immediately after the repair is complete.
How long do control arm and ball joint assemblies last on a Subaru Xv Crosstrek?
Service life varies widely depending on road conditions, driving style, and maintenance. On smooth roads with average use, assemblies commonly last many years and well over 100,000 miles. Frequent off-road use, pothole-heavy roads, or lack of lubrication on greaseable joints shortens that lifespan considerably. Inspect the assembly any time you have the wheels off.
Should I replace control arm and ball joint assemblies in pairs on a Subaru Xv Crosstrek?
It is strongly recommended. Both sides of the suspension experience identical stress and age at the same rate. Replacing only the failed side leaves a worn assembly on the opposite side that is likely to fail soon. Replacing both at once saves on labor, ensures balanced handling, and means only one alignment job.
