Default Very strange vibration,Anyone?

I had the Kmember installed and the car has been aligned.It steers perfectly.I can let go of the wheel and the car track straight and true.Only a hint of pull to the right when i hold the wheel but I was told my power steering being unhooked casues that?

Anyway,if I hammer the car from say 60 MPH and beyoned it starts to vibrate.Its threw the steering wheel and comming from under the car?

I havent got a clue as to what it is.
I'm gonna check my under carriage to make sure it not something touching.But I dont get a vibration until 60 or better,nothing from idle to 60?

Could my pinion angle set incorrectly do this?
Or pehaps a tire that no good?Maybe my 12 bolt is acting up?Converter took a crap?

Does the Kmember force more driveline vibration threw the car?I'm gonna look at the darn thing tommorrow on a lift real closely.

I did have set of old street tires that I put on it.
They sat for a while and had flat spots.

Seemed to balance out good but had the thump thump thump feeling until I did a couple of hole shots on them.After that they seemed okay.Do u think these could be bad and causing the viabration?

FWIW there old Protrac Bias Plys.

Could it be your tires are out of balance. I know I've had my skinnies vibrate and simply rotated them in refrence to the hub and it cleared things up.

Good Luck

Sounds like a balance issue to me.

Yep thats what I think too.
I looked under the car and nothing it toucing.

Looks like a tire change is in order.
The car hasnt felt right since I put these old Pro Trac's on her.

I picked up 2 tires last week. BFG T/A Radials 275/60/15.There going on tommorrow.

I think I'll get rid of the JUNK 165 Vderstein too
They have some broken belts on the sidewall and I think this might be the vibration that I'm feeling.I know the M/T Front sportsmans are heavy but the right tire for the street.

Thanx guys....

You guys need some better performance shops. I've never heard of these types of problems out here. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Joel,
Re-clock your Verter by 1/3 and see if the vibe gets worse or better. Other than that, I dunno <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> Bent Driveshaft?
