i have a sr5 4wd with the offroad package,i'm doing this project saturday when i have to change the oil, if you don't have to remove the calipers please enlighten me on the process, that would be awesome, i've got 102,000 on the original pads and the dealer told me they were getting kinda of thin when they did the balljoint recall, i do do alot of towing with the truck, a 450 gallon water trailer every other weekend, plus a 16' trailer of firewood frequently in the winter months, thought i'd let you know how the truck is used, it has never let me down, thanks for all your help and info, jim
