2004 chevy venture front vibration

I have a 2004 chevy venture that has developed a front end vibration when steering is turned to the right. No vibration at all when going straight or to the left. It seems the same at a very slight turn or sharp turn to the right. Ideas where to start looking ? thanx

 

Simplest thing to do, is rotate your tires & see if it makes any difference.(front to back, back to front) Could be as simple as a bad tire. If that doesn't cure it, start checking for loose/worn tie rods etc., and maybe an alignment problem. Do you remember hitting any potholes lately?

 

Is this just a vibration, or is there a noise accompanied with it?

 

Yes I did rotate the tires, front to back, back to front. Didn't help. And yes there is a noise that sounds like a tire rubbing on
something, but that is not the case. Ball joints and tie rod ends seem good and tight, so I guess maybe a front end alignment is next. Thanx.

 

i am assuming that you did check tierod ends, not just decided so.
tierods go bad either, and about the only way to find out is to remove it and roll on a piece of glass. unless you can see it move in the rack'npinion.
if it sounds like rubbing, it does rub. some rubs are simply very hard to spot. 1st thing that comes to mind is brakes splash shield.
IMHO, tires should be CROSS rotated, not just back to front. now you changed the rotation direction.
several other things to look at (though i feel it's one of the tierod ends): ball joints, hub bearing, struts suspension parts, ENGINE/TRANSMISSION MOUNTS, as they can cause powertrain hitting undercarriage or sidewall at tight turns. along with rubbing noise, btw. virtually impossible to see, though. and can manifest itself in one direction only.

 

May be a wheel bearing going to hell, that would be my guess without hearing it physically. This vehicle is one of the many GM vehicles that have wheel bearing issues. And about rotating the tires on a front wheel drive, fronts go straight back and the rears cross to the front. Rear wheel drive vehicles are just the opposite. All wheel drives you cross all 4.
