steering vibrations over bad roads...pls help

[cro320]

Hi guys
I have a 1990 320i 2-door with M-technic suspension setup and power steering
Last year I rebuilt whole suspension..new CAB's (E36 3.2), control arms etc...
underneath is tight like it was never been driven before
BUT

on bad roads full of bumps, potholes etc car makes me nuts..every time I hit something with my front wheels, steering wheel jumps in my hands, and it's really annoying...it feels like dash is going to fall apart :(
Is this common or I need to check something?
I know that E30 has very positive feedback through steering wheel but this is just too much...I hate it in city driving, out city on open fine roads car feels like brand new!
I am out of ideas, please give your opinions

Thanks;)

Torque the hell out of the steering column nut under your dash.

Isn't that only for airbag cars?

I think you may be right. I just saw 1990 and made an assumption. Skimmed right past your model and location.

Did you replace the tie rods? Inner and outer
