Okay,
I started noticing a noise coming from the diff a little while ago, I thought maybe the fluid level was low so i had it checked it turned out to be fine. I figured that the diff was just a little noisy. Well a few weeks ago i started to here grinding from what sounded like the left rear wheen so i thought maybe a break pad was hung up or maybe a wheel bearing.. Soi am trying to find a place to take it t to get it checked out for about a week and during that week i decided that it was time to change my spark plugs because the car just turned 100k, not to long after i changed the plugs the car started to shake like the pinion angle was off really bad.I figured that it was do to the rear end problem and it wold go away. I got the car back today andl it's shakin' like Michael J. Fox
the plugs are correct
the gap is correct
every bearing in the rear end was changed
the clutch is not slipping from what i can tell.
the shaking starts in 3rd around 1800rmp and in 4th about the same rpm

i was thinking driveshaft a weight may have come off or something.

WHAT THE HELL??

thanks,

Check your wheel weights and make sure your driveshaft is fine. Otherwise, it's time to start looking into your differential.
