Help with strange knock???

Going back to post #16,I assumed the noise is not something hitting the steering gear. The test I outlined has to be done with wheels on the floor, and at normal track width; that is, the car was just rolled in and not jacked up.I think the knock is elsewhere, but I outline these tests to prove it.
-I suggest the the following: you and a helper, one at each front wheelhouse.Grab the fenders and lift the body up an inch and very gently let it down.Then push it down an inch. Repeat several times.Then increase the lifting height a bit and repeat the test. If the noise is in the shocks or bushings, this should prove it.
- Next,have your helper lightly apply the hydraulic brakes and put the trans in neutral.Now you rock the car,increasingly vigorously,front to back. The brakes need to be just loose enough to allow some wheel rotation. If the noise is in the rest of suspension,or the caliper mounts, this should prove it. -Finally, get the drivers side front wheel in the air and spin it up.Check it for reasonable roundness, and blown cords, and Sidewall BULGES. But the big test is this; with the wheel spinning, have your helper gently apply the brakes. Try this several times with various brake pressures similar to what causes the knock.And finally have him lock the brakes while the wheel is spinning at a pretty good clip. If an UCA mount is loose the energy transfer to it might show up here.
-One thing worth mentioning if you have power steering;That box is a pretty good vibration insulator.Almost nothing happening downstream of it will get into the steering wheel. I say almost. And anything tapping on the steering shaft, most definitely will.Good luck.
