I just installed my TRD rear sway bar this past weekend. I thought it would be a pain but it only took about 40 minutes. I just jacked up the rear and put it jackstands. The hardest part was getting the old bar out after it was unbolted. I discovered that taking it out the drivers side pulling towards the front of the vehicle was the best. I have not really had a change to really test it out yet, so the jury is still out.
