Truck feels like breaks go On then Off HARD HELP!
 

My 2009 Ford FX4 runs perfect and never has any problems..

In the last two days, when I am getting off the Highway on a sweeping right hand turn, going slightly up hill and the truck feels like the breaks are going on and off or like the tire is rubbing real hard off and on..I mean Hard. Weird!

It only does this on that same particular sweeping right hand turn up hill.. I have gone in circles in parking lots, I have gone onto other sweeping off ramps, and I have turned the truck right then left and every way else to try to duplicate...IT ONLY DOES IT on this OFFRAMP! EVERY DAY......

I am Mechanically inclined, and to me it feels like the front or rear Differential, Posi, is not working or it's trying to go into 4x4 etc..... HELP!

Sounds like a traction control system issue. Do a TCS search and see if you can compare notes.

Try doing the ramp with the TC off...press and hold the button until it flashes on your dash.

I thought you had to hold it until it stopped flashing and turned solid? Maybe I'm holding mine too long for no good reason.......

a simple press just turns ESP, pressing and holding turns off TCS, ESP and TSC

But do we need to hold until it starts flashing, or until it stops flashing? My manual is all the way outside in the garage.......

It's a traction control issue, there was a TSB just recently issued for it. Just had mine done last weekend and the problem is gone completely. I'll see if I can track down the number.

I would like to know the number also.
