I am nearing my wit's end with this issue. Hopefully somebody may be able to point me in a better direction than the current one being taken.

I have a 2002 S10 Blazer, 220,800 miles -- majority highway. Recently began noticing a vibration up-front or under the floorboard on the left side, with a slight moan and grinding noise. The vibration was worse when at moderate speeds (30-50 mph) than what it was at highway speed and every-so-often the steering wheel would pop when turning to the right; usually when driving on a gradual curve to the right and never when actually turning the vehicle to the right.

After having a couple of others take the vehicle for a ride to confirm what I was hearing and feeling, we determined to examine the Hub Assembly on the front left, which was replaced. The axle on the left side, which was also replaced and the universal joints on the back were replaced along with the right side Hub Assembly, as well.

Frustratingly enough, the vibration is actually much, much worse now than when it was before all these parts were repaired. The vibration and shaking is now its absolute worst at highway speed but is noticeable at any speed. The steering wheel feels very very tight and pops occasionally when turning it right (that aspect hasn't changed a whole lot) but I have noticed the brake pad has recently become tighter, as well. Brakes were examined and seemed to be okay else they would have been replaced, too.

So here I am, I feel like I'm throwing all my money and time into something that has only gotten worse. Anybody experience this kind of thing before?

Thanks in advance.

 

Is there still the grinding noise?


Have you tried putting the front tires on the back to check if the tires are out of balance?


Have you checked the steering components? Idler arm, tie rod ends etc.

 

Just a thought... have you checked the condition of the motor mounts ? I didn't realize mine were toast until I replaced them just for peace of mind ! Possibly the trans. is rubbing the trans. tunnel and unloading the frame at the same time.

 

Don't keep us in 'suspension?' What did you find?
