Vibration through steering when turning left

Struts would not cause vibration problems, A CV joint could, turn your vehicle in a parking lot hard right, make a circle than turn left make a circle ,if you hear a noises you have a cv joint problem. If you feel vibration on the steering wheel its in the front, if you feel it in the seat its in the rear.
Tires out of round & Balance very common as well brake rotors cause vibrations.

Any wear or play in a bush or rod usually gives a 'knock' or causes vibration, not a humming noise.
If there's play in the steering wheel that may be due to a worn steering rack and pinion.

A worn ball joint can cause a 'crack' noise and depending on the wear, vibration that will be felt through the steering wheel. A worn ball joint can also cause the car to pull to one side.

A humming noise suggests it is either a brake rotor/pad, or a worn driveshaft or wheel bearing.

possible wheel bearing at fault. if it heard/felt more when turning or swerving and is a growling type noise, more than likley is. possible bad tire shouldnt be over looked. is abs light on? most often when wheel bearing is bad a speed sensor ( within wheel bearing ) will go open, setting abs light. vehicle needs to be ran on a hoist to try and duplicate noise/vibration.

Has to be a drive axle,most likely an inner joint,should be able to feel the play if one is bad (jacked up to let the wheel spin freely).
Also. If the front suspension is weak,or lowered, the CV axle will bottom out in the inner plunge cup and make a terrible vibration.

Jack up the front end and put stands under it and block rear wheels. Look at axle boots and see if they are cracked. Try turning wheel back and forth sharply and see if you can hear any clicking. Problem could be outer axle joints. If the boots are cracked or you hear a clicking noise you will have to replace the axle. The axle and boot come as a complete unit. Please let me know what you find out.

That sounds like a left front wheel bearing gone bad My friend.. turning right transfers weight to the left side and it probably has a roar similar to a turbo fan jet.. Try it and lemmie know.. thank you

hello have u rotated the tires front to rear then drive and see if u still have the noise and vibration if drive yes while driving slowely turn the steering wheel left to right just a small amount if the noise changes its probably a front wheel bearing if that doesn.t help drive the truck till you get the vibration then let up on the gas pedal does the noise go away if so you might have a bad u_joint but do the tires first how many miles???????

just checked this out a while ago:



Wheel Hub Assemblies: Systems and Diagnosis of Worn Hub Assemblies & Bearings
Front wheel hub assemblies and bearings control the position of, and reduce the resistance of, vehicle wheels in contact with the pavement. When they fail, front wheels may not be kept in position and vibration and noise usually develop. Symptoms that normally develop as a result of these worn parts include:

• A humming, rumbling or growling noise which increases with acceleration or as the vehicles turns
• Vibration felt in the steering wheel, which changes with vehicle speed or as the vehicle turns
• Looseness or excessive play in the steering wheel (especially while driving over rough road surfaces)
• A loud, constant grinding noise when driving the vehicle (heard in the most severe cases of a wheel bearing failure)
• Pulling to one side when braking.
• Roughness - with the vehicle of the ground, roughness or vibration when rotating the wheel
• Looseness - with the vehicle off the ground, looseness when wiggling the wheel back and forth (Looseness may also indicate a worn ball joint)
• Excessive brake pedal play can also indicate sloppy or excessively loose wheel bearings
• ABS failure in the system may be related to failure of the ABS sensor in the hub assembly or the internal sensor in the wheel bearing

I had similar problem with my 03 trailblazer. It had a low dull hum in the front end with a little vibration being felt in gas pedal. Noise increased over a couple weeks and was louder turning to the left and quiter turning to right. A GM mechanic friend of mine replaced the front right hub and took care of the problem. Hub was about $160 at Autozone.

Check the U-joints and axle baerings. But its most likely because the truck is in four wheel drive.
