Just because the door alignment is true, doesn't mean that the aerodynamics are true. The entire uni-body has to be perfectly in tact. These are the aches and pains of an imperfect world. AKA wear and tear.
EDIT:
If the weather strips and window is fine, then you have uni-body misalignment (the car is warped). It is breaking wind and causing noise. 70 Kmph is a slow speed. Usually wind noise is common at much higher speeds.
Strips are tight and checked. Windows closing properly as well
there may be a **** trail hanging off and whippin in the wind
rubber weather stripping flattened around the doors
windows not closed properly
Check the weather stripping seal around the door...if its not sealing tight when the door is shut you will hear wind whistling...
I had an accident with my 07 nissan altima sedan. And since I got the car back after getting it fixed I hear a lot of wind noise as soon as I hit 70 kmph. The driver door and side mirror were replaced. They align properly with the rest of the body. Any ideas what's going on
