Others have commented on the rear TAB. I rented the tool from IPD and there are references on this forum on how to make one. The trailing arm has a front bushing that is in a metal sleeve. Many experienced bricksters maintain it is not necessary to replace it as it seldom wears out. You decide. If you replace it, unless you own or have access to a hydraulic press capable of 5-7 tons IMHO it is not worth your time to pound or cut or whatever. I paid a machine shop $30 to press out both L and R and press the new ones in without deforming the trailing arm etc. in about 25 minutes total plus travel time. Same for the front control arm - any bushing with a metal sleeve is going to be a PITA to get out. Unless you are endowed with a shop at home with lots of tools and you have lots of time, I would take satisfaction in removing and replacing and saving about $300 rear and $250 front doing that.I personally prefer poly bushings for the firmness without harshness but I have no idea how they react in cold climates or in winter - I live in So. Calif. Also important to have a torque wrench for final assembly.
