i bought this car 8 month ago, it was a CAT C car, repaired at the rear end right side of the car. it was fine until few days ago noise started when i took five people in the car . when it go over bumps or holes right rear side of the car make big noise, its like bang...bang.

actually the garage guys said they have already repaired it to high standard but i thought shock absorber is gone, i took it to them but they said they only give 6 month warranty on the cars they sell... however they looked at it and replaced the bushes and they said it will be fine but they wont do anything if it happened again... few days later the same noise started and i noticed that when i look at the car from behind right side of the car is lower than the left side....

can anyone please tell whats wrong with it? is it the shock absorber or anything else? how much does it cost to repair at local garage....?

i also got one more question, it's regarding my friends car....he also have nissan 2002, but after recent accidental repair the garage person forgot to activate airbag... so the airbag is flashing on his speedometer..do how much do they charge to put a new code ? thanks

i am sorry, i am asking too many questions...
