It depends, but replacing the whole control arm is generally the best course of action.
Just replacing the bushing can certainly help save on parts costs in the short term, but it can cost more labor to remove the bushing than it does to replace the entire control arm. Depending on the design of your car, other bushings or ball joints on the control arm may also be wearing out and potentially not be serviceable. If choosing to replace the entire control arm, all bushings and ball joints will be brand new.
The only scenario when a bushing replacement may make sense is if the control arms are significantly higher in price and do have a serviceable balljoint (if applicable).
If you're interested in finding the correct control arms for your vehicle, head over to fcpeuro.com and start by entering your vehicle into our vehicle selector.
Once your car is added to the selector, there are a couple of important ways that we advise correct fitment.
The first is the "fitment indicator" shown on the Product Page after selecting a part. This box is below the "add to cart button" and has two states. It will either say " Yes this part fits" or "Part may not fit, click to verify".
Sometimes the green box will be accompanied by extra fitment notes. These notes may be independent of the information gathered by the vehicle selector. IE: VIN-specific options, need to be taken into account when determining overall fitment.
