wicked bad shake.75-90mph...HelP!!!

First thing I did lol
Ive been dealing with this shaking for a while. I have been pouring through the forum trying to find an answer. I have checked my LBJ's and they have no play. I just purchased new tires, road balanced and an alignment.
This is what has been happening. I will be driving on the highway and around 72-75 I feel a constant shack in my seat (*** to lower back). It gets worse around 80-85 but then will almost not shake around 90-115mph. There is no shake in the wheel but of course I feel it because the whole car is shaking.
I have recently changed my diff fluid with Valvoline Full synthetic and my new tires, nothing else really. Could be diff be F'd up??
My control arms seem ok upon visual inspection. What else could this be????? Driveshaft? I am really do not know wtf is going on.

Hey everyone,
I was contemplating starting a new topic on this but when I realized this was common and my problem was almost exactly similar I figured I would just add on to one of these threads.
I have a 2000 GS300 with 115,6xx miles on it. I experience a very bad shake around 50-60 MPH but it is intermittent. It will go away when I get up to 70 or dip below 50. Like some have said before me, I experience it sometimes very badly, and other times I find that I do not have any shake at all.
At 111,xxx miles I replaced the following items:
1)Front lower ball joints
2)Front upper control arms
3)Front right wheel bearing
4)Two front tires were moved to the rear and I had two new front tires purchased (Rear tires had flat spots causing a very slight vibration)
Of course, when this work was completed a four wheel alignment accompanied it.
It should be noted that this work was done in the month of December, and since I live in the northeast, it was considerably cold during this time of the year. I am telling you this because I have only noticed this problem over the past three weeks, and it has been VERY hot. I know many of you live in the states and can also attest to the fact it has been hot as ***** the past few weeks. I keep a very close eye on my tire pressure and when the car is running after a 40 minute drive with about 20 of those minutes on the highway, the pressure will go up to about 38PSI. I lowered the pressure in the tires a good amount to counteract this but I still get a slight vibration at the said speeds.
I just wanted a few opinions. I am almost convinced the remedy will be another four wheel alignment and a tire balance. Since the suspension work was done in the cold and now it is very hot I feel as though things might have settled in a way to alter the alignment. Furthermore, the heat could have made the tire pressure spike in such a way as to throw off the balance.
Thank you for the input.

Try replacing the #2 control arm bushings with poly bushings. My guess is that this is the main cause of most people's shakes even though the bushing may visually appear ok.
I got rid of all of the shakes when I replaced these bushings. I also replaced my LBJ and inner/outter tie rods due to mileage and likely stress from the worn bushings.

Sorry for the double post but I have an update that may lead some people in a different direction.
I balanced the front wheels today and did an alignment to no avail. Still a vibration in the steering wheel.
After driving home from the mechanic's tonight, I noticed that the front right wheel was MUCH hotter than the front left wheel which lead me to believe that one of my calipers is sticking/is seized. Further supporting evidence of this is that there is a ton of brake dust on the wheel as compared to the other side. Could this have anything to do with the intermittent vibration? And is this dangerous to drive with?

check your brake caliper, let your car slide at 10miles per hour, if the caliper is sticking bad, it should stop your car in few seconds, put it in neutral and let the car roll with no power brake. I also had this problem in my is300, in my case, turns out my tires are not in good shape, shaking around 50 to 70mph. I lowered the tire pressure to 25 and it eliminates the vibration, proves that it has something to do with my tires

Warped rotor, bents wheels, jack up the car and spin each wheel see if you get a consistant spin. Press on the brake and see if it releases pressure...i had same problem..bent rim, and warped rotor

I didn't read everyone's posts, so if someone helped you already ignore this
1) Check all 4 of your tires, make sure they are not bubbled
2) Make sure all 4 wheels have been balanced correctly
3) If your lowered & haven't got an alignment go get one(but buy toe correction arms first)
4) SLOW DOWN haha
