Carrier/rack problems of the 2005 Volvo XC90

I bought this car at 12/12/2013 when I test drove the car the dealer had the radio on and I never suspected any noise at the time. After I bought the car I kept hearing this knocking noise at first I thought is was the ski rack making the noise then when my husband drove it he said it was coming from the tires so I took the car to my mechanic and he check it a out and found multiple problems the suspension,inner tie rods,axles,sway bar, steering,bushings etc his reply was how did this car pass inspection with all the problems available take the car back and ask the dealer to fix the problems. I took the car back and ask the dealer to comply they would not I told them they had received a faulty inspections on the car so I took it to another mechanic same response. I then called the safety inspectors and they came out to check out the car and found nothing. I then took it to another dealer and they reported the same problems and added a cracked engine mount. I then asked the inspector to come and look at all the things that Volvo found that the safety inspectors missed he agreed and saw but only wrote a report I still have a broke car that was faulty inspected. I want the dealer to fix my problem and they have refused I could sue them for getting a faulty inspection and selling a lemon but I fell like I am stuck I need to know what to do from here I have already paid for several things the rack and pinon is the most important I have to fix but expensive and the bushings and tie rods are going to be the next thing I repair I really don't have the money to fix them I am paying 7000. 00 for a used car and I fell that the dealer and the inspectors are crooks and used a faulty inspection to sell a broke car please help.

Counterbalance shaft bearings breakdown in Nov 2009 and had repairs done at independent repair shop; August 2010 cylinder head leak/crack which brings oil to water coolant. Repair shop advised to get rid of car 2005 xc 90 v8 Volvo. I am fearful of driving this car. To repair and replace engine and new transmission too much $$$ for this Volvo. With no guarantee. Volvo needs to own up to the bad quality of this particular model. I feel it is dangerous to drive with so many cars on the road. It's an accident waiting to happen.
