I am not to familiar with replacing front stuts in a V70. When I purchased the car the right front spring seat was replaced because of a constant sqeek noise etc. Now I hear almost the same noise coming from the right front. I can see the coil spring not turning freely, and binding once in a while make a vibration down through the coil spring. Is there an upper bearing that should be replaced and if so, how hard a job is this? The car has 100,000 miles on it, and is a 1999 V70. thanks.
