96 disco 148,000 miles. I've got several alignments and the steering wheel is never centered after. I seem to have to compensate when going straight ahead on bumpy roads and sometimes it shakes over ruts at highway speeds. I got tapped a couple of times in the front. Ive also got a feeling like the swivel drive shafts were out of sync with the last alignment. Had recent front drive shaft rebuild as well. shocks are good. Thanks

 

find a shop you can trust......( I know that can be a stretch ) have them get the frt end off the ground and check ALL the suspension components for wear.
It sounds like the allignment "tech" alligned the wheels without taking into considderation that one or more components may be worn out or loose.....this same thing happened to me and after much searching it turned out to be loose bolts holding the panhard rod....and fyI.....when the bolts were loose the wheel was centered perfectly going straight down the road but I had the "death wobble"....after we tightened the bolts...no more death wobble but the wheel was off center going straight> it's all connected

 

Thanks for the info now I need to find out why my brake pedal feels low.

 

Your brake pedal feels low because you need to flush your brake fluid.

Once all the front end of the truck is all be fixed/corrected there is a dajustment to center the steering wheel on the steering box.

 

Yea I found the bolts. what is the steering wheel adjustment? I thought it was the drag link.
