Steering Vibration

While driving, I will come to a full stop, then turn right or left. As I start the turn there is a vibration coming from the front. It only last a few seconds then stops as the turn is completed. My mechanic checked it out and nothing, but I am skeptical. Any thoughts?

 

Like a vibration in the steering wheel, is it jerking around? Or do you feel it more in the floorboard? Do the rpms get really low?

 

Have you done anything with your power steering pump/reservoir lately, like open it? Or have it up, like on jacks, front wheels off the ground, and turn the steering wheel? Sometimes air can get into in the PS system and cause that sensation. Need to turn it lock to lock a few times while sitting in the ground with the engine running to bleed the air out if so.

 

Same happening to me. At low rpms w/ wheel cranked? Thinking it could be CV joints. Check for grease. Getting it checked out in a week.

 

Did you leave it in 4WD?

 

Too few details on your truck. We can help you, but you've GOT to help us get a clearer picture.

What year, cab type?
Any accidents?
Have you lifted the truck, and is it running stock tire size?
Are you running stock wheels, aftermarket, or Toyota wheels from another truck/SUV?
Did you recently have any fluids changed, ESPECIALLY the rear differential?​

The lower balljoints are the Achilles heel of these trucks. So much so, even Toyota had a recall on their own parts, and there's a running joke (that's sadly a reality), if you don't run OEM lower ball joints, you're in for a world of hurt. There's an ongoing gallery of shame of people who failed to heed this warning, thousands long, pictures of people with a front wheel parallel to the ground or stuffed into the cab. Some companies, like Moog, have had major recalls on lowers in the last years due to major failure: You basically can't trust anyone but OEM for LBJs, only Toyota took time to over-beef them up.

That said, I'm thinking a few possible things:

• You've got knobby tires, maybe oversized, and you're rubbing at low speeds.
• You've got Toyota wheels from another vehicle, and the different offset/spacing has you rubbing.
• You've got a ball joint (upper/lower) or tie rod failure looming, or other steering/suspension causing this, or allowing tires to make contact
• You have an LSD rear end (look for a sticker on your rear axle/pumpkin) and someone recently change the fluid with inappropriate fluid, and what you're actually feeling is CHATTER, which sounds/happens similar to your description.
• You're in 4HI on pavement and trying to turn the wheels at low speed, which is a big no-no.
