Accelerating From Stop - Bumpy
When accelerating from a stop, it feels like you are running over small bumps before getting up to speed at which point it stops. Any idea what this is? It's hard to explain the exact behavior.

Could be bad tires, wheel bearings, shafts. You have to troubleshoot. Put the car in the air and turn the tires to see if anything is noticeable

It's really hard to explain. It's not really bumpy but it feels like bad bearings or something. The car doesn't bump. It only occurs when accelerating from a stop. If you accelerate slowly, it doesn't happen.

Here's a better explanation. It feels like you're running over about 20 pieces of pea gravel when you accelerate from a stop. Not a rattle, but just running over.

Had the same issue with mine if you made sure you tires were good then it's either bearings or shaft. You have to troubleshoot which one. Mine was the bearings going bad so I did an assembly replacement. I was troubleshooting on and of for about 2 weeks.

ever solve the problem I kinda have the same thing going on, mine only seems to happen when I am accelerating from a stop when I don't give the car much gas, it also seems to happen more when I am under a quarter tank of gas and also while I have the ac going, it doesn't do it all the time just sometimes and when it happens if I press down harder on the gas pedal the car works its way through the bumps slowly until shifting or right before shifting when the acceleration begins to kick back in again, the car will then run through the gears just fine, instead of pressing down on the gas more if I release the pedal for a quick second when I press the pedal again the issue will be gone.
