A Hint ... Put grease or heavy wax on the trailing arm bolt before installation. I had a case where the bolt rusted and "welded" to the hole so badly that I had to replace the arm. The other problem that could arise is that if the part rusts and welds to the hole, you could get a false torque reading. It could be torqued properly at the nut end and be loose at the other end. Just a suggestion Nick Kemp
