Car shakes between 40-50 mph only when it's cold?

I thought it might of been an unbalanced driveshaft, but what does temperature have to do with anything?

[jspeedm]

try checking tire pressure

[nisco]

and have you gotten an alignment recently?
Could be that as well.

Edit: Just saw the 'only when cold' part. But could still possibly be alignment.

Tires balanced, tire Pressure, is there snow packed in the rim or on the lip of the rim causing your tires to be unbalanced?

[handinpants]

this has nothing to do with suspension, shaking when temperature is cold does not cause that kind of problem.

[jspeedm]

water in the tire could cause that problem

The steering rack on the right side was out? Nissan tech said the bushing was worn. Maybe that's why it had something to do with temperature. Its fine now, but I have new bushings coming anyway.
