Dropped my truck off at Ford this morning because my front right shock is leaking at 22k miles, IF and IF Ford decides they'll replace under warranty what is my down side (if any) of having one new shock and one used shock on the other side? Aside from having to have do the mid-perch again on the new shock will I have any regrets down the road of having it replaced rather than just going ahead and buying 3.0? I wanted to wait on 3.0 until I had more miles on the truck and it was time to replace/rebuild all shocks not just one.
