Steering wheel jerking during turn

[olyelr]

Well I am confused as hell. When I checked the other day at full lock both ways they both turned fine with no hesitation. Just yesterday while I was pulling it into my shop to service it- it happened again, so I stopped immediately- jacked it up and checked. Sure enough. Passenger side binds and locks up and tries to jerk the wheel straight. What's weird is it just kinda disappeared then resurfaced. Scary part- I towed a camper and a deckover with our farm truck on it a combined 2000kms like that :/

She's gone into the shop since it's still warranty work. Just hope it is done by tuesday when I have to pick up my family and the camper. I suspect they'll only change one which kinda sucks. I would do both if I was already putting time into it and had it all apart anyways.

To answer your question- the jerking was VERY pronounced. 2-3 inches at a time. Felt nothing like the pulsing of the power steering.

is this pulsing dramatic or just slight felt in the steering wheel? Is it like .5-1inch and soft feeling instead of a mechanical jerkiness? how far are you turning?
the power steering box is just that, power steering.
when you crank the wheel and the steering box to the end of its designed radius, your feeling that flow of power/fluid, as the steering gear is trying to decide which way your going.

if you ever get a chance to drive some old tractors or heavy duty machinery with power steering, You get a good feel for how power steering might react to steering inputs.
You can steer lock to lock with a finger, but that Power steering box is doing work.

Its taking your steering input and transferring that effort into a power steering system.
When i turn all the way to either lock, and hold the wheel, but slightly loosen my grip, the power steering builds up to help me turn the opposite direction.
this feels like a pulsing in the wheel, trying to get me to turn the other direction.

That's not it...at least not in my truck. Mine has done the same thing since new. It got really bad and the dealer found a bad u-joint. Still did it after it was replaced.

About the only time mine does it is when I am on a cloverleaf entering a highway...so about 30-40 MPH and maybe half a turn of the wheel. It's just a slight twitch of the steering wheel. The truck is not sliding or tires jumping. I'm guessing it is a pressure fluctuation in the pump. It is a bit disconcerting.

As I mentioned, my dealer has looked at it, did replace an axle joint and the problem didn't go away.
