Weird steering wheel vibration after 70mph

Well this just happen today, at first i thought it was the road itself but after going past tha bad part, it was still vibrating, and it only happen after 70mph, if i went 60 i couldnt feel a vibration any more.

The vibration is very minimal, like the vibration from 2 ps2 controllers, its no where near the vibration when i had to replace my tie rods, calipers and rotors. im thinking it could be the front wheels are off balance, but i got my wheels replace, a couple of months ago, and i also got my tie rods,etc replaced a about a year 1/4 ago.

Also i don't have any power steering, could that cause a vibration, but i have had no power steering for a year and a half.

any ideas

Check your strut rod bushing bolts. Also check for play in the upper strut mount.

check wheel balance again....start their first then go from there.

check wheel balance and look for a hop inn the tire and for signs of seperation, even the best tires can get seperation even after a littl ebit of easy driving. i'd check the strut rod bushings to there easy to check and caused what you describing on my car.

well today after 1 1/2 years im gettin my rack and pinion replaced, i did it a while ago but the rack was leaking and now i got it replaced it had a warantee, and ill tell them to check the front tires,

and weird thing yesterday i didnt notice any vibrations and i took it up to 90mph, and was cruising on the highway at an average of 70mph and there was no vibrations.

and its ganna be great having power steering again, its really hard to countersteer without power steering,
