What do you need a hydraulic press for to build a 2004r? Get a driver set. V notch a chisel to remove the bushings. Some can be difficult.You can get a cheep hand compressor on ebay, for the return springs. But the best for the job is always a foot operated spring compressor. No special tool is needed for installing servo unless checking clearance on pin. And still doesn't take a special tool. For the lip seals just use a feeler gauge. For setting up the rear get yourself a old yoke to keep the out put shaft in place. If you don't have a hold for a bench get someone to weld the old yoke to fly wheel or something for a cheep stand . I used a sunshell from a 4l60 and it works great.
