you can easlily change that yourself if you have some standard tools, knowledge and about an hour. (this is considering you dont have a machine press in your garage... if so just ignore everything i posted)

once you get your replacement bushing take off your contorl arm and put it in a vice. then burn out the old rubber/inner metal ring with a toarch/welder (the quickest for me)

then using a hack saw cut a line in the outter metal ring that is stuck inside the hole in the control arm. next use the welder to get both sides of the cut warm (i dont even go red hot).

then using a punch or chisle give a few good wacks to the line you cut and it should just pop out.

to insert the new bushing i normally throw it in the freezer long enough to shrink the tolerences for a press fit. then i heat the hole in the contorl arm and insert the new bushing.

BE CAREFUL... when i have used this method the heat will bring the bushing back to normal size rather quickly, meaning dont have half of a bushing sticking out when it expands or else you will have to press it in the rest of the way.

i may be making a DIY for changing all that shit in the front end, cause like next weekend im changing all the bushings and joints in the front end
