Have a question about 3 areas around the wheels. Here is a pic of the rear lower control arm. You can see there is a gash in it, I assume from a curb or something, no idea. Do you think that it needs to be replaced? I inspected it real good and I don't see any cracks or anything other than that gash. These pics are of the cotter pin that is helping hold the rotor on. The first 2 look fine to me. The 2nd two look like maybe that pin needs to be replaced? Looks kinna jacked up. My dad says it's fine but what do you guys think? These pics are of the bushing by the rotor, I thought the rubber boot looked like it was laying in a jacked up way, but all of the wheels had the boots looking like that, that is normal?
