I hope you can get it fixed, but don't skimp on your studies. You won't be affording too many fancy upgrades while digging ditches for a living.
I had the vibes before with factory bushings so I got new brown dog polys. But thanks for your help. I'll be replacing it as soon as the weather allows! Thanks

It may not be the problem you are having, but it is a definite possibility. When mine started failing, it caused vibes at a certain RPM.
Quick question, how would pulling down on the drive train cause the pulley to stop causing vibrations?

Great! Please be a good cop and not a scumbag cop like so many have turned to being. When you watch your fellow servicemen break the law and you do nothing about it makes you an accomplice, and cops don't do so well in prison. CTR

I don't know, but you don't want to be putting your hands on moving car parts as you will have little chance of drawing your service pistol without your hands.


The pulley is just one of the possible explanations of your vibe issue.

Now run off and hand out $500 tickets for broken tail-lights. Johnny Law expects full literacy from the populous, but sadly can't deliver it himself. Maybe you can understand why people all across the country have become quite dissatisfied with our police forces.
