I have a 2007 Ford Explorer Sport Trac XLT V6 w/ 76,000 miles. While driving back from a short mountain bike trip, I noticed a clicking/scraping noise that slowed and sped up according to how fast or slow I was driving. I started feeling vibration shortly afterwards. Stopped at my residence hall (only a mile from where the problem started), and got up under the truck to see exactly what was going on. The front drive shaft has a LOT of play in it. I can move it up and down, as well as rotate it fairly easily. The play all seems to be near the joint towards the rear of the truck (I don’t know the proper name- i’m assuming it’s a coupling between the front and rear driveshaft).
Is this a “replace the entire forward drive shaft assembly” issue, or is it a “replace the u-joint” issue? I’ve never worked on this truck, so I’ve no clue exactly what is broken or worn.
