Power Steering Pump problems of the 2003 Volvo XC90

My 2003 Volvo Xc90 has been to the dealer several times including over 3 times for same problem when I purchased the vehicle in 2006. All recalls have been fixed, front axle, wipers etc. I have purchased 4 sets of tires, tires boston Volvo installed and my 17 year old son received a complete blow out because wrong size tires. I continue taking to same dealer and since owning the car have had the same noises in front of car. Boston Volvo has stated in October and since owning the vehicle can find nothing wrong, April diagnosed with need new drive shaft after having car for 2 days but could not really fine anything but drive shaft. A strong fuel smell stated fuel pump does not need to be corrected. I need new muffler and taking to my own mechanic the real issue is transmission service urgent and need new transmission. Volvo did not diagnose this problem and my son is driving the car! my son is driving a lemon that is a danger to himself. Taking to Volvo does nothing, they cannot even diagnose and give wrong info given to me. I am currently up to over $8,000 in damages and still owe on this lemon. I need new transmission, muffler, still car vibrates and front end noises from whining, thumping etc.
