Had both CV's and shaft replaced as passenger side boot was busted and all the grease leaked. Started vibrating when turning left between 5 - 25 mph. Mechanic replaced tie rods (old ones were not bad) - problem remained. Had tires balanced and rotated - no change. GM mechanic suggested the hub so a new one was installed - problem remained. GM mechanic now "thinks" its a loose bearing in the transmission.
I think its in the power steering but I am only an old "under the tree" mechanic.

Re: Vibrates when turning to the left at low speed
I do not think this can be the power steering, when the fault is in the power steering you also normally get lack of steering assistance. When I talk about power steering Iam talking about power steering pump and rotary valve. When this system is malfunctioning , you lose steering power and often get fluid leaks. See here how power steering works. This however do not exclude completely the possiblity of a fault depending on car steering gears , even if the fault would be quite unusual. Moreover you would understand if there is a steering fault even at lower speed, or lifting the car. The transmission fault also look odd, even stranger than the power steering, and I do not think a transmission problem and cause the car to pull on one side. I would double check the newly installed CV joint, suspensions and shock absorber, tires, even rear tires balancing, suspension joints, bushes or components, front brakes.

Grinding noise upon turning is normally one of two issues. First, and most often, it is caused by a worn out outer CV joint. If your vehicle has more than 50000 miles on it and the axle shafts have never been replaced, this is what I would suspect first. In addition, CV noise will be louder when turning under power (gas pedal pressed) than when coasting into a turn. The other possibility is a front wheel bearing assembly. These are not as common, but do wear out as well. The wheel bearings will usually make no noise when going straight, but will make noise upon even the slightest side to side turn. CVs on the other hand, usually grind only when going into corners or making left or right turns. If you suspect a CV joint, but don't have high mileage, you could have a torn CV boot that resulted in the grease that lubricates the joint being depleted and causing the noise. You can inspect the out boots visually for tears....grease leaking out usually leaves telltale spatters in the wheel wells also. Replacement of the CV joint can be done, but it is usually cheaper to replace the entire axle shaft as they are serviced as a unit.
Is it a clicking only while driving? Maybe more so when turning? If so then it could be a CV joint. The boots tend to tear on the outter joints and the grease slings out (sometimes seen on the fender). Then you hear the ball bearings rattle around in there. Its very ******* them and should be fixed ASAP. If it breaks because of loss of grease it could leave you stranded.
If this is the problem then the CV most times can be repacked and the boot replaced. But repacking with grease does not fix wear and tear. It is not much more work to replace the whole shaft and CV shafts with inner and out joints ready to go are fairly cheap now days.
That a CV joint you're describing. That boot protects bearing from dirt getting in and grease from getting out. You don't have to hit anything, they split with age, deteriorate and sometimes actually twist on shaft and gives the appearance like you smacked something. Replace or have someone replace CV joint and boot on that wheel and you should be good to go.
will try to help. you may have bad passenger axle. pop and crack anytime on left turn only? or just howling? bad cv joint on passenger side. look under front of car while safely in park. look on inside of each wheel, see the rubber boots? there will be two on each side,drivers and passengers side,see any grease leaking around those rubber boots? if so, then that may be where your problem is. thank you for choosing fixya.com
it usually signifies a broken CV joint. check the drive shaft for the left side. the outer rubber boot is probably torn, this allows grease out and contaminants in. It is wise to replace the drive shaft as an assembly instead of just replacing the outer CV joint- they usually come with a lifetime warranty.
