Frame And Members problems of the 2002 Jeep Liberty

I am experiencing a rattling sound when driving uphill or downhill through driveway, traveling 5-20 miles an hour. I took my Jeep 2002 Liberty 2wd to get serviced and received recommended repairs: prosteer control arm with ball joint upper center, remove and install propeller shaft to replace universal joints on both ends, rear wheel bearings, tail pipe is welded to muffler, muffler does not meet design specifications and should be replaced due to exhaust leak as well, remove rack and pinion, complete rack as does not meet design specifications and is leaking. I was driving about 25 mph and my rear right side tire was smoking profusely. I pulled over and noticed the gray smoke from my tire. I took the car to check the rear breaks. They were fine but was told that I had a leak from the exhaust pipe which dripped on to that area. The car has 75,806 miles. I was told that I could loose control of vehicle and entire area can collapse during traffic due to these issues. Aside from these issues, I am experiencing a whistling sound, problems with rear drivers side passenger power window regulator which produces grind-like sound. The window came off and I was told that I needed a new regulator for the window. I'm also experiencing a red stain in engine oil drippage on ground. Finally, strange odor from car -odor continues to be present whether I wash the carpets and seats (smells like mold/mildew or skunk).

Jeep Liberty 2002 / there was a recall on the ball joints. The dealership is telling me the ball joints are bad after only 25,000 miles after the dealership did the recall repair. Ball joints typically last somewhere near 100,000 miles. The car is driven on the highway in florida about 8,000 miles a year (no off road at all). I feel the recall repair was subpar and want the ball joints repaired by Jeep.

Consumer stated the left frame weld was inadequately welded, dealer has been contacted.
