my 2004 VX70 has a "nibble" while in a long high speed turn (i.e. freeway ramp), the steering wheel rotates slightly in my hands. When standing still, all seems tight and secure. Suggestions?

 

nib·ble (nbl)v. nib·bled, nib·bling, nib·bles
v.tr.1. To bite at gently and repeatedly.
2. To eat with small, quick bites or in small morsels: nibble a cracker.
3. To wear away or diminish bit by bit: "If you start compromising too early . . . they nibble you to death" (People).

v.intr. To take small or hesitant bites: fish nibbling at the bait.

n.1. A very small quantity, especially of food; a morsel.
2. The act or an instance of nibbling.

 

Thanks migbro... I guess the definition "v.intr. To take small or hesitant bites: fish nibbling at the bait" is the best description. during the turn it feels like a small to medium sized fish is nibbling at bait attached to my steering wheel.

 

errr........wobble?

 

Worn control arm/bushings can cause a wobble at high speeds, as can wheel bearings. That's where I'd start.

 

Thanks XCMomma for the hint. The CA bushings were replaced, but that was a long time ago, I will be disappointed if it is needed again, but I will see. There may be an interaction with the following.
I found an interesting (and obvious) cause and effect. The power steering fluid was low after topping off the problem described here diminished significantly, it has begun to creep back since then with no loss of fluid. Not I can generate what feels like a pulsing pump by sitting in park, with the engine running and holding the steering wheel to the right or left enough to engage the power steering pump.
