ive got a 996 2000 and there seems to be under braking a vibration problem that comes through the steering wheel if i brake from anything above 60mph, it gets worse the faster. ive had the wheels balanced and reskimmed the discs and new pads and the problem is the same. i know that the bottom wishbone has play in them as i can hear them sqeak over bumps and can saw the play on the ramps, can it be any other problems as i dont wont to keep throwing money at it..can anyone throw lite on this, also are the wishbones hard to change and if i do does it need to be tracked?
