We have 3 company work trucks. They are F150's 2WD V6 - one is a 2008 and two are 2007s. They have all had thrust bearing problems. We just had the #9 thrust bearing replaced in the 2008 for the third time. The trans hasn't failed but starts making a whining sound at all speeds which varies in pitch relative to speed. The 2008 has had it replaced at: 40K, 60K, and now 70K. One 2007 had it replaced at 60K and 90K. The other 2007 had it replaced at 50K.
Our dealership says they've never seen anything like it & that our trucks are the only ones they've seen this on. They are suggesting it's happening due to driving behaviors. All 3 trucks have a single driver and aren't switched or shared. The 2008 doesn't carry or tow. The 2007s both carry hundreds of pounds of tools daily. This just seems like too much of a coincidence to be driver induced and that we're the only ones with these issues.
Anyone else have issues like this on their newer 2WD drive F150s or thoughts on this?
One of the fleet maintenance F-150s where I work is making a noise like you are describing. Drove past me yesterday and I looked and thought "That doesn't sound good."
In December '11 I bought a used '08 F150 4X4 and when I drove it home from the dealer it was making a very loud dieseling noise. Took it back to them and, after some back and forth, they said the engine had a bad thrust bearing. Still under warranty they would get Ford to replace engine. The truck allledgedly only had 31,000 miles. They're going to get me another truck. I can't wait for them to get approval from Ford and install a new engine so I'm dealing on another truck. Big hassle because technically I still own the other truck.
