A friend of mine has a 2000 Ford F250 with a 4" lift and she's experiencing some sort of drivetrain problems. I could make some guesses, but I'm no expert and can't tell for sure what it is by her description, but it involves some slippage/slopage and abrupt engagement from a stop (see her description below). I feel bad for her because she's been to a few different mechanics and/or "experts" who all disagree on what the problem is. One told her she needed a new tranny, another told her she needed a new ring/pinion, another said her tcase was shot...
She needs an honest, knowledgeable mechanic who will make the effort to really determine what the problem is. Any reccomendations would be appreciated.
I asked her to summarize the problem and here's the e-mail she sent:
When I stop there's a jerk in the rear end (no noise or clunk) and when I accelerate it does the same thing. Mechanic said that the drive line starts to engage and then stops and then grabs again to spin. You know that feeling when you have something in the bed of a truck and you stop and it slides forward to the front of the bed and hits it and then when you accelerate and it slides to the tail gate and hits again? That's almost the same feeling here only in the rear end. Hope that helps.
Here's what she's had done so far:
I Changed out the differential oils (front and back and both sets of spider gears looked perfect, no metal shavings, and oil was clear didn't need to be changed), changed out transfer case oil, changed out transmission oil and tranny filter, put on new carrier bearing and dropped it 1" for the lift.
