Hi, I had a R32 GTR. Use to had hard lower spring on it. I swaped the this set and got a stock shocks with stock springs from just jap. Once I change the just jap one to my car. It had some noise came from the left front shocks or something else which is around the suspension unit, it only happend when the road surface is realli bad, such like very bumping road. I gave the car to Pedders to do the 28 points suspension check. also gave it to powerplay imports to check. They both can't find where is the noise come from. Pedders saying the upper arm bushes worn. Powerplay saying the left upper control arm buggered. Both of them saying driver side loader cu boot have to replace a new one. I dont realli understand all of this. And the just jap shocks and springs are all good. But before the car had lower spring and shocks, it doesn't have that noise at all. I dont know why, realli wanna get rid of these noise. Please help! I am at Sydney, is there anyplace can fix that problem???
