Thnx. I was curious.
R. diffs in Ford's smaller stuff seem rather delicate, but I expect better from an F150..... then again, I have a friend who could break an anvil, so wanted to know the usage pattern on yours.
Understand that driveline noises and shutters are notoriously hard to diagnose without isolating driveline components. That said, what happened is the clutches in the limited slip took a dump. However, just as this truck was about to come out of warranty, the front lock outs got replaced under warranty. The driveline shutter felt like it was coming from the front end and so I brought it back to the dealer that replaced the lockouts. That dealer insisted I needed a transfer case—even though all functions of the transfer case worked. I asked them if they had dropped the front driveshaft to isolate the the front end, and they claimed that they had.
However, I've NEVER heard of an F150 shelling its transfer case even with the high power, high torque ecoboost engines and I confirmed that by calling up the biggest 4WD rebuilder in the state (BeeLine). But because the dealer claimed that they had dropped the front driveshaft, and without a hoist to lift up my truck and play with it myself, the rear end went undiagnosed until it got so noisy and chattery that it was obvious the differential carrier clutch packs had taken a siesta. At that point I ordered in a Eaton (Detroit) TruTrack, new carrier bearings, shims, and new ring gear bolts and swapped out the differential carrier. The Ford dealer has subsequently gone out of business.
Off topic: anybody want to start a pool on how long Youtube will ban streaming this video because I named it "Race Driver A YouTube Short" over the perception that it is somehow related to promoting r-a-c-i-s-m and not making a bearing race driver to install a bearing?
