Q: whats the typical cost to replace a rear passenger bushing 2005 galant 4cyl.

There is more than one bushing at the wheel position you are inquiring about. The upper control arm has bushings as well as the lower control arm and the trailing arm assembly. In addition, the sway bar has bushings. The cost will vary quite a bit depending on exactly which part you need replaced. You can specify the part you need by clicking on "get a quote" at this link.
