You don't have to take the rack out of the truck. I just did mine. Just take the bolts out where it mounts to the cross member and it wil move enough to do it with out disconnecting anything else. Push the steel bushing out and then the old rubber. After I got the steel bushing out, I grabed the rubber with a pair of channel locks and twisted it and broke it loose. It takes a little work, but they will come out. Then just reverse everything. The mounting bolt have a pretty good torque on them. I can look after church tomorrow if you need it.
