I have a real bad vibration in my steering wheel when I am cruising about 70 miles an hour. What in the world could be the cause. I have had it re-aligned and rebuilt the steering coupler.

Try checking the balance on your tires. Also check the condition of your shocks. They may be shot.

Before you have the wheels checked for balance, see if there is any mud caked on the inside of the wheel. It can throw the balance off.

You may also have a bad tire (like the belts separating or flat spots)

ive also heard that if your u bolts arnt aligned they will couse one hell of a vibration.

Yeah, keep it simple first...

Any dirt, odd weights on the wheels ?

Any slightly bent wheel ?

Did you also have it aligned,... or just tires balanced ?

Is the shake only in the steering wheel, or do you feel some body shake, or driveline vibration ?

Is the shake only speed dependent ?
Or does it come and go through the gears as the engine rpm rise and fall...

I have an '86 RC and I found mud caked in between the front calipers and the rim.  She never shook at 70 before latly when I hit a few holes.  NOW and even with the mudless rims... holly hell she will shake your fillings out of your mouth over 50!  Its in the steering wheel, truck, tranny... the whole thing!  Plus when I am at a stop the WHOLE F**CKING TRUCK SHAKES TO A POINT WHERE IT BUSTED MY CAN OF COKE IN THE DAMN CAB!
SO... any further comment on this issue would be great... thanks.
