I had my car serviced this week and was informed that the bushings are on their way out on my left rear lower control arm. I'm just curious if I should just replace the bushings or do the entire control arm instead. Any pros and cons to either?

 

It would be cheaper and less wasteful if you can find the bushings you need, and have a press to remove / install them.

You have more options when it comes to complete control arms, but you'd have to do both sides.

 

It's a lot easier and better to just get new arms with new bushings already pressed.

Highly recommend that.

And don't use poly. Downgrade compared to rubber.
