jst did my rear trailing arm bushes today. Didnt have a tool so thought i'd make 1. All i did was find 2 circular bits of steel about 6 inches diameter, 5mm thick, drill hole in middle of both discs, get threaded bar aroung 9 inches long, 2 nuts with washers to fit the threaded bad and bob's ur uncle. Piece of piss to do on car. All i did was remove both wheels, remove both rta bolts, drop the arm down and burn old 1ns out. (left old casing in place as i replaced with poly-bushes.) then press new bushes in by nut on threaded bar. Bit of a twat 2 burn out but fun 2 set **** on fire. (watch fuel tank tho obviously) good luck guys
