On each end of the upper control arm shaft, where the bushing sits, how important is the surface condition on this area? Mine have some rust pitting. (See the attached photo with the arrow) .
I am trying to figure out if the shafts I have will still work or should they be replaced.
This is my first time redoing a front suspension. Tell me if I understand this correctly....... With the bushing in place on the control arm shaft and the bolt with the large washer put through the bushing and screwed in to the control arm shaft, the serrated edge of the bushing's inner sleeve digs into the control arm shaft and locks them together. The inner sleeve of the bushing never rotates around the end of the control arm shaft when the car is being driven.....Is this right?
If the above is true, it would seem that the surface of the control arm ends would not need to be super smooth..... Right or wrong?
Any thoughts would be appreciated.
