I learned recently that my 70 mph vibrations would change when I as in full time four wheel drive. This helped clue me in on the issue being the slip joint, or so I believe, to be the cause of the vibration.

I purchased a used front drive shaft from ebay, from a 99 I believe.

My intent was to take the old, original drive shaft to a shop and have it repaired, but I have yet to do that.

I've been running the replacement drive shaft for a few months now, and actually have to use the speedometer to tell how fast I'm going on the highway!

It was a big improvement for highway driving.

I've recently heard, and felt some vibrations, and I suspect the u-joints need to be replaced in this "used" driveshaft.
