Need mechanic reccomendation for 2000 F250

[H-K]

I sent her down to J&G Transmissions and they drove the truck and don't think it's a drivetrain issue. He said he thought it was something shifting in the suspension.

I'll send her to have somebody look at the suspension -- either Madsen Auto or Wide Open.
thanks

...a straight kinda guy...

So no rainbow stickers in the window of his shop?

He's just a real easy going guy. He would give you his last beer if he thought you needed it more than he did, kind of guy.

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.

I work for Ford and deal with this all the time. If it's a limited slip drain the diff and refill with 2 bottles of friction modifier.

If not, I would put my money on a worn slip yoke. We have a TSB (tech service bulletin) published advising guys in the field to lube the slipyoke with teflon grease. My .02
