Bad vibration when accelerating 99 Blazer 4.3 - 4WD
Hi everyone,
Whenever I take off from the stop position I would feel a reasonably significant vibration through my steering wheel and on the floor board of my 4WD 99 Chevy Blazer 4.3 vehicle. At first it didn't seem to noticeable, but gradually over time its becoming more pronounced, but as soon as I got to rolling speed (20-30 miles an hour) it disappears. Yesterday, the vibration was so significant when taking off (definitely something wrong) that I though about stopping the vehicle and towing it home. I know it not the front wheel bearing because I change it less than 3000 clicks ago. Lately I've had the slightest cracking sound, similar to the sound you get when opening the drivers door, which hasn't been lubricated lately (You know how ****ty the door mechanism hardware is on these vehicles) when coming to a stop, which could be part of the problem. Has anyone ever had this problem? What could it be? Any help would be greatly appreciated! Thanks, Rob |

Dead u-joint would be my first guess. You can block the wheels and put
it in neutral, then go under and start shaking and twisting driveshafts and front axle ends.
