I concur with both of you (Lee-CI & Joint Venture II) and have had same experience with all my trailers over the past 25 years. However the proof is in the pudding that these will likely wear faster than rot--see pics. So to be safe, I am rotating front to back. Its gonna be quick easy do it myself with cordless impact gun and torque wrench, so why not.
