there is a random knocking in the left front of this car. the whole LF suspension was replaced due to my girl whacking a curb doing burnouts. its sporatic, and everything is tight and the car drives straight and feels safe. two shops and myself have investigated and found nothing...any ideas? it sounds as if the exhaust pipe is banging around, but is obvi. not...its driving me nuts.

What year car, engine, transmission, etc?

Since you posted in 4th Gen, this is what I would do,
Support the car with jack stands to remove the weight from the front wheel in question.
Then, using a spring compressor, compress the strut spring enough to remove the tension from where it is sitting.
Then, grab any part and shake it. Grab the next item, shake it. Continue until problem is found.
Normally, everything should be tight.
The loose part found is your problem.

Sway bar mounting and its connecting links?

go back on the invoice from the shop and see if the strut mount was replaced . the top strut mouuts are for crap on the 4th gens . well not crap but they go after a while and rattle around and bang .

u replaced the suspension... if the wack was big enough to damage that, then there would also be damage to the rim, tyre, and very good possbilty to the stub axle assembly, bearings and calipar backets.
All of these should have been replaced without question also.

This was my first thought as well.

Look at the body seams and their sealer for separation.
Look at the body seams/parts for rubbing, witness marks, tearing, etc.

strut was shot...frozen like a rock... also the shop found a couple loose bolts...the guy was fired from the shop...this was the last straw apparently
