Just got back from the mot station and as I half expected my qts has failed. it's been knocking over bumps for a while so expected one of the front bushes to of gone. According to the mot tester it's the upper front arm on the drivers side that needs replacing as the ball joints are worn. Are there any brands to avoid when replacing this or is it audi only? Haven't got a lot of cash to throw at it currently its also failed on the near side cv joint gaiter being damaged with half of it missing. I have a mate doing the work but how much will I be looking at in parts?
