Hey, when I hit speeds of 70 pulse I have a slight vibration in the steering wheel. What would cause this? Could it be a misalignment in the from end?

Loose nut holdin' th' wheel?

Could be a tire/wheel problem, or even a bad shock. Loose suspension components, such as ball joints, tie-rods, or even bushings. Wheels bearings can cause a high speed vib., also. Looks like time for a complete check-up in the front !

It might be as simple as an out of balance tire. Any play in the wheel? Any unusual wear patterns on the tread? Big Fish38794.2707060185

Sounds like a front tire balance problem. Wheel alignment won't cause vibration unless so much tread is worn that the tire gets out of balance. You also said it occurs at a certain speed...another clue to tire balance (maybe an out of round tire or wheel, but less likely).

In general, vibrations through the steering wheel is a front balance problem...vibration through the seat and floor indicates a rear balance problem.

I've had a similar problem with my Ricerside Gold '69, but at 50 - 60 mph. I took it in for an alignment and at a frame alignment shop after a reputable Corette owner who manages a Firestone shop told me he couldn't align it. The frame shop told me they couldn't align the front end because of: shot control arm bushings (upper and lower); lower ball joints; and a questionable idler arm. I had all repaired - didn't need the idler arm. It is a lot tighter now, but still vubrates. Guess the only thing left is the wheel bearings - I know they haven't had any attention for several years and had been thinking I'd do them this spring anyway. Easy Rider38794.3640625

Vette(s): Silver '81 mostly original C3. Silver interior, bilstiens, big sway bars, headers.
Some quick checks to do...
- wheel balance. One of your wheels may have tossed a
   balance weight.
- hit any kerbs lately ? or large pot holes ? If so a
   rim may be bent
- delaminating tyre. Had this happen to me once, not
   pretty.

First thing I would be doing is to swap my front wheels
to the rear, rear to the front, and go for a drive. If
vibe follows the wheels... well you know where to start
looking next !

Joel and Gunslinger are on the money; tires, wheels, or balance. Also the slight possibilty of a broken or worn shock. I have experienced this on numerous cars and to the vehicle, anytime it was doing it at a specific speed it was always in the tire or wheel. Sometime the tire can appear completely normal but has a seperation. A quick test is to move the rear tires to the front. If the nibble in the steering wheel is gone you have narrowed the problem to the two tires that are now on the rear. If the tire is really bad you may now feel a consistent bump in the rear of the car.

Vette(s): 1975 C3 Red, T-Tops, Black Interior. All I need is time and money! Getting there!

You may feel it worse from a worn or broken shock, but the source problem is still an out of balance or out of round wheel/tire.

Alinement will not cause a vibration unless it is quite severe.  In that case the tires would be very badly worn.   Worn front end parts such as tie rods can also cause the vibration, but again, there would be tire wear.
