Ok... we all know the drill.... S197 front ends make all sorts of noises.
Mine recently began making a serious clunk when turning, coming from where I believe to be around the drivers side front of the car. I can feel it HARD in the floorboard, but not the steering wheel. It sometimes occurs right at start up as I'm turning the wheel away from the curb. LOUD! It happens many times when turning the car through a twisty road at speed. At speed its hard to determine which side the clunk is coming from. But I hear and feel it.
So I replaced the strut mounts with GT500 ones, inspected the strut itself, lowering springs, spring isolator silicone wrap, mounting nuts, and alignment/cam bolts & holes. They all look fine. Suspension mounting bolts are all tight.
I also installed a new Ford Racing sway bar kit and bushings, and new Moog end links.
Vehicle alignment went normal. Alignment guy didnt find anything wrong.
Last year I replaced the lower control arms with GT500 units. The mounts and ball joints appear good. I also installed Ford Performance front wheel hubs. Added GT500 Brembo brakes at that time also. No clunk until now.
I'm planning on installing a bump-steer kit before this seasons HPDE events.
The tie rods look good, and no bad feel through the steering wheel when the clunk happens.
I have poly motor mounts... maybe one is loose?
Transmission mount bad?
Rack & pinion loose?
Can anyone think of something I may have missed?
