If the bushings are really good and not distored or have cracked rubber, you may want to let them be. Installing new bushings is not a funny job, although not rocket science either. I call this type of job "just a matter of inconvenience".

The main reason the carriers (dog bones) have bushings is to isolate the front tire road noise from the body of the car (especially when braking), so there is less noise in the car. One thing to watch for is cracked aluminum bushing core where the bolts go thoughout the bushing (the SEL had one with the aluminum cracked). I changed them (all four) on the SEL and the SEC because I like things done right and once only, although the ones on the SEC were in good shape. A set is not cheap either, IIRC I paid ~ $220/set of four MB bushings. To make things go faster, I got a used set of dog bones from the JY, I installed new bushings and when time came I just swapped the ones on the SEC with the ones from the JY reworked (one evening job).

Thank you @liviu165 The dog bones were in good shape and the bushings did not show any damage or extreme softness so they are will stay.

Installed a bushing the redneck way. I didn't have any special tools, so I lined up, and use the the hitch of my truck and a rolling jack as a makeshift press.

It took all the weight of my truck to press that damn thing in....

Don't feel bad there 5CYL, the "redneck way" is a common way to do things around here. There is another term you'll likely see (maybe even be "accused" of being ), "Bottom Feeder". I proudly wear that tag as well. Ya just do what ya gotta do to keep these fine road machines on the road instead of in a museum and off the scrap heap

Some days it's just not worth chewing through the restraints
