when you rotate the tires and their is no change check the c/v axle -and hub 25k is not considered new have changed hubs that have gone bad at 10k -look into ball joints,upper lower bushings ,tie rod,struts the latter can cause vibration but usually at all speeds
Does the vehicle make any noises while driving? If there is a "growling or roaring " noise associated with the vibration, check the right front hub bearing. If there are no noises and only vibration, check the right front upper ball joint and control arm bushings. The Trailblazer's upper ball joint and control arm bushings become worn and cause the tire and wheel assembly to shimmy while driving. The vibration stops when turning left because of weight transfer to the right side which keeps the wheel steady for a moment. Also, check the tire for irregular wear.
It wobbles? like when your driving it vibrates and stuff. If so its not your tire. It could be anything. Loose lug nuts. Bad Hub assembly. Suspension. Brakes. or if it really is the tire. it might be out of round. or need to be rotated to the back of the vehicle
Yeah , it's a fairly simple repair, All the wheel studs must be replaced and lug nuts also.Closely examine the wheel or get competent tyre replacement company to double check for damage ! Remove the brake disc caliper and brake disc itself (usually 2 cross head screws) , tap off (gently) it may be stuck thru corrosion / rust etc , Broken studs can be knocked out(towards drive shaft ) of the hub assy with a suitable drift and hammer (splined into hub) . The studs are a servicable replacement part. Check all other wheel nuts as this is usually a result from poor fixing or wheel replacement recently .. Good luck
Easiest way to check and see what the issue is. Jack up the front end of the vehicle and support it on stands grab the top and bottom of the wheel and move it back and forth check to make sure it is not in the lower ball joint, if it moves back and forth very freely it is either the bearing or the lower ball joint. Grab the front and rear of the tire and move it watch the tie rod end and see if it has slack in it the other wheel should move as much as the one you are moving.
THIS NOISE IS USUALLY THE HUB. HAVE SOMEONE GO WITH YOU ON A TEST DRIVE. GET THE ROARING TO HAPPEN AT ITS LOUDEST AND GENTLY SWERVE THE CAR LEFT AND RIGHT. DON'T BE SURPRISED IF YOU THINK BOTH HUBS ARE BAD.
LIFT THE FRONT OF THE CAR AND PUT IT ON JACK STANDS. PULL OUTWARD ON THE BOTTOM OF THE TIRE WHILE PUSHING INWARD ON THE TOP OF THE WHEEL. IF THE WHEEL MOVES EXCESSIVELY YOU FOUND THE HUB THAT IS NOISY.
USING A MECHANICS STETHOSCOPE YOU CAN SOMETIMES HEAR A ROARING TYPE NOISE ON THE BACKING PLATE SIDE OF THE HUB WITH THE ENGINE RUNNING AND THE TRANS IN GEAR. TRY NOT TO GET THE SPEED UP TOO FAR ESPECIALLY IF YOU CAN HEAR THE NOISE AT LOW SPEED, YOU DON'T WANT TO VIBRATE OFF THE STANDS.
