If the shaking is at the same place ie: for example only between 35 and 45 mph, it would indictae a tire balance problem.

Otherwise we need more info to diagnose that.

Could be a tire going bad, as well. Low speed shaking, that goes away, usually indicates a bad u-joint or tire.

Well when I drive from 5-30Mph you can notices but with higer speed it feels like it go away but you can notice for sure when you start slowing down from 30Mhp. Is like the *** in the back go left and right and I haven't notices any weir crunshing noise and the tires seem to be fine with air and ware. The only thing I could think of is that maybe someone change the tires around with out taking it somewhere to get them balance.

If it's a side-to-side shaking, you prolly have a tire seperating, bent wheel, or bent axle.

Well, I when to tighten the lug nuts but barely can't even get a tick out of it. I did on two nuts but that is about it. This is having the car fully on the ground. I am not sure if ya wanted me to lift the car up to do this.

Check your watts linkage thoroughly, sounds like at least one bushing is toast allowing the rear to wander.

Just an additional suggestion.

Just makin' sure. My lug nuts got loose at one point and my rear end started shaking like hell. Another few blocks and they would have come loose, and I would have lost a tire

Well I guess I will take my car first thing and get all the wheels aling first and then see if the shacking is still happening.

Hey guys, Thanks for the info but I found out today at Discount Tire that my tires walls where separating and was giving me a weir lump. They also found that the tires where 11 years old. So, Pretty much I end up replacing all 4 tires for some good regular tires for now. Later on I will get nice wider tires and maybe better rims. Anyways I just felt I should let ya know what my problem was.

Thanks for all ya help.
