90% of the time vibration while braking is a result of "rotor runout". You might want to check your front rotors, they might have worn too thin. They tend to also warp if they are this thin. Check them out.

If it is bouncing almost like a ball then you also need to check the steering stabiliser. Just remove one end and work it in and out. It should feel just like a good shock absorber. If there is no resistance and you are able to move it too easy OR if it binds and does not travel smooth. Replace it.

Can you drive past the vibration like go faster past that point?
You really should get your U-joints checked. They might not be worn out however I have had them seize up. As a matter of fact when I replaced a seized up one on my 84 Bronco my gas mileage got better.

Just wanted to kick this back to the top of the board. Well, is the vibration fixed? What was it?

If you suspect the driveline...I would first check the slip joint at the rear of your driveshaft....Mine felt tight untill I pulled it apart...that is when I discovered 1/2 of the splines were worn to nothing....also...the centering ball on the front cardon...to make a long story short...I had a similar vibration...$180.00 to a local driveshaft place...for a brand new driveshaft that they also balanced....and...my vibration is gone.

good luck
Greg

One thing you may also want to check is the track bar bushings. Mine were worn out and where the track bar bolts to the shock tower was lose.
