Hi All I have had a issue with my r32 gtr for a while now and am wondering if anyone has any ideas.. When im driving and have my hand on the gearstick and depress the clutch or accelerate or decelerate I feel a slight knock through my hand like the gearstick it being hit buy something, I took it to Nissan and got their head mechanic to take a drive and he thought it might be the gearbox mounts or engine mounts,i didn't think so as the stick moves not the gearbox but I thought well ill give it a go and replace the gearbox and engine mounts..but no improvement.. I thing the the drive shaft might be sitting on a worn bearing and maybe rocking up and down when I accelerate of depress the clutch ..any thoughts?
