There is a reason we ask certain questions....

are you DIYing? Do you have a bushing press? Do you have a ball joint tool? Are you somewhat competent or does this push your limits?

This will tell us to recommend the bush or the whole arm.

95 for each bush vs 260 for each arm. ($190 vs $520)

If you are at 120k+ miles I might do the whole arm.
If you are 60-80, do the bush. In another 60k then just replace the whole arm.
