Got a knock going over bumps?
In most cases a front suspension knock while going over bumps is caused by bad front shock bushings.
Usually, if the bushings are that bad it's time to replace the shocks.
It is very common on all T-Birds to have bad shock bushings.
If it's not the shocks then look at the ball joints.
Shocks will make more of a drum roll kind of knock where a ball joint will make a more specific bang or knock with each bump
