I may have derailed here.Yea you can buy the bushings, control arms, and ball joints as separate pieces
I'm talking about on my 2008 Tacoma. Toyota doesn't sell ball joints for 2003+ 4Runner or 2005+ Tacoma as individual items. You can only buy a whole control arm for these trucks. So as a result whether or not I could potentially get control arm bushings alone from Toyota I can't say because to replace my BJs I had to buy control arm assemblies anyway.
Aftermarket sells all the pieces and parts, so it's always an option if one decides not to stick with factory parts, of course.
For your truck Toyota does sell BJs alone so you wouldn't replace everything all at once. I'm not suggesting you should do arms or BJs necessarily in your case.
Sorry for the confusion.
