TODAY is a Great Day to visit our Store and order the parts you need for your truck!
Nothing wrong with replacing your bushings, no need to replace the whole arm as the Arm itself is NOT a wear item, bet was though is the replace the shaf as 99% of the time the inner sleeve for the pivot bushing is rusted to the shaft anyway, so order up some new bushings and a new set of shafts and cut your current shaft in half and then use a air chisel to drive out the bushings , start by getting under the outside lip,and work it out. , for the install you can use a ball joint press to press in one new bushing , but you are gonna need a stand up press to press the other one on, just remember to install the new shaft with all washers before you press in the other bushing..lol and have something cut to where it firs between the opening between the opening on the inside of the arm, otherwise it will try and fold up the arm when you press the other bushing in, I just cut a section of exhaust pipe and that works fine. just did a set for my buddies caprice yesterday in a hour.
I have used a press before on control arm bushing.....Just never had them with a shaft through the whole darn thing....ALSO the GM service tool to remove the control arm bushing is almost identical to a ball joint press......YEA I'm sure the guy at the garage would love to see you pull up and tell ya "Yup gotta replace the whole arm....." with dollar signs in his eyes.....lol....
