Possible Ball Joint issue?

[misfit77]

I have read numerous threads about bad front ball joints. I don't think my issue is a ball joint.

Few things first. 96 GS-T Spyder with 74K miles. Ball joint recall was performed. Car was stock when I bought.
I am the second owner. The previous owner is an older lady neighbor.
Issue noticed after having a small accident when I ran off road and hit a pile of dirt.

It first started randomly when I had a hard launch. It is not a click...it is a hard thump like a 3lb sledge to the subframe. No sounds on bumpy roads or turning. Heck this car rides smoother and quieter than my 07 G35.

Now I am noticing when I have a hard stop. Both launches and stops cause a hard thump to the driver side.
Shortly after the accident I replaced the rusty tie rods so I could aligned it. I honestly can't remember if the thump was before or after the tie rods.
Car is now lowered about 1.5" frequency and magnitude of the thump is same.

I have put the car on the lift numerous times looking for evidence of the control arms hitting something. Nada!

Any ideas what it could be?

Thanks

Have you checked your motor mounts

Good question. I will check.
I can see how the launch does it, but braking while clutch is pressed?
I have seen weird crap in my lifetime so anything is possible.
