well, just to wrap up this thread, I did replace the trailing arms, subframe bushings, rotors, parking brake shoes, and wheel bearings. (and a mess of other things)it took 3 days, and with 2 new tires cost pretty close to a grand. of course that includes buying a few needed tools.although i could not dedicate myself to full time work under the car, so prolly about 1 1/2 days.
the biggest issue was the subframe bushings had become one with the bolts. must have soaked up 4 + hours just on those. wiggling back and forth with a breaker bar, and finally getting them out. then cutting the bushing away with an angle grinder and dremel tool. anti seize compound on everything that went back in.
wheel bearings are quite a job, too, altuogh now that i know what to do , the next time shouldn't take more than a couple hours.
I want to thoank everyone for their helpful advice, with out it i probably would still be under that car.
