Driveline Vibration

[ajeeperwannabe]

I searched and sounds like most vibration is about 50mph, is this at 50 even with the accelerator pressed? I just put a 3 1/2" lift in my '87 and now have a vibration when decelerating and aplying the brakes.

it can get worse, its death wobble or maybe some light stages of it. i'd make sure my tires were aligned and balanced...

*COULD* be DW, but lets examine a little.
1) Only happens on braking or deceleration, i.e. when nose heavy

2) Did this just start, right after lift?

3) Have you gone back and checked all bolts make sure everything is tight?

4) Did you correct caster with lift?
Did you replace shocks/swaybar/etc?

5) Did new tires accompany new lift?

All these are areas to look at.

If they all check out, time to start replacing BJs and bushings

did you replace the track bar i know I had some awful DW before i replaced mine.

It wasn't DW. But it was the need for high angle yoke, driveshaft was rubbing the yoke. Fixed the yoke, it all went away.
