​​​​​​AAAAAAAAAAND NO MORE RATTLE IN THE STEERING WHEEL AND FLOORBOARD / PEDALS! Dealership did not show a new part number for the upper fastener.... of course no bulk bolts in stock. Went to ace hardware and found an allen head bolt, and a stainless lock washer. Little blue lock tite for the threads. Ran home and installed it, and drove to work. Pulling out the driveway i immediately noticed that my steering was much smoother yet “tighter”. Off the bat i could tell it was GTG. So my advice to anyone having issues with a rattle feeling in the steering wheel and floor board, replace the lower intermediate shaft. Its cheap enough that its worth a shot.

I believe the needle bearings were bad in the old shaft. The bearings were notchy and i believe the rattle was the result of out of tolerance needle bearings. I had not realized how bad my steering had degraded, until i replced that shaft.

Awesome! I will be ordering the shaft tonight. I will let you guys know if it fixes mine also. Thank you very much.

Cool. Make sure you report back. I will add that my local dealership still showed national backorder. You may need to try an online vender if you cant get it locally.

I have the 6.2

Did you do something to fix it? Mine still has slop at the firewall, but every other 250 ive looked at has had some measurable movement to different degrees. Im so happy i figured out that my lower shaft was bad. I now enjoy driving my truck again.
