l would like to know if it safe to use parts from a salvage yard to replace the LF and RF lower control arm bushings. any help is requested. No BS please
When l look at the used part how will l know other than cracks if it a good used part

Well, you can take a close look at them and if you notice any cracks, it is probably not a good, but bushings are pretty easy to determine if they are usable not just by that. Before buying, take a look!

well depending how much they are and how much your paying for the installation,if they are not much cheaper that new and same labor,and your keeping the car go with new
