wheel shaking when cold (need help)

[newbe40]

I can't seem to find what is causing the front end to shake it is worse when its cold and will almost go a way when it is warm unless I push the car through a corner then it will surface again.The car is a s14 se with tokico's and tien's I have replaced the tension rod bushings, pillow ball mounts and inner tie rods the car has 186,000 on it with stock se wheels and 225/50/16 zr dayton tires that only have about 10,000 miles on them.I have had the car on the rack and can't find anything loose. Any ideas what to look for would be appreicaited.

"cold spotting" is a posssibility..a tire can give itself a temporary flat stop overnight in clod weather depending on its belt construction, etc. Tis usually goes away after 15 minutes of driving at 50-60mph...
