Hi,

If this only happens when you accelerate, it could be related to a wheel bearing, an axle CV joint, or even a motor mount.

Where do you feel the roughness the most, in the steering or seat? Also, when you are driving steadily, is there any noise? Is there a clicking sound when you accelerate or make a turn?

I'm trying to narrow things down. Sorry for so many questions.

Let me know.

Take care,

Joe

I feel it in the steering wheel and the seat and gas pedal. Only when I accelerate it will smooth out then.

Since it only happens when you accelerate, then it is likely related to a CV axle/Joint. That is when the most pressure is on them.

Take a look at this link:

Now, do you ever notice a clicking sound when turning the steering sharply in either direction and accelerating? Take a look at this link for possible symptoms:

Let me know.

Hi,

The loud pop could be a ball joint. If it is loose enough, it could cause issues.

Do this. Lift the left front wheel off the ground. Place your hands at 6 and 12 o'clock. Wiggle back and forth to see if there is any play.

Next, with the tire about 4" off the ground, place a pry bar under the tire and see if there is play up and down in the wheel. Also, inspect all rubber bushings.

Take a look through this link and see if anything mirrors what you hear:

https://www.2carpros.com/articles/popping-noise

I attached an exploded view of the front suspension components and highlighted bushings to check as well.

By any chance, are you in an area where the roads are treated for snow and ice? If you are, there were issues with the subframe rusting. That is the large steel frame under the engine. Check that to make sure nothing has rusted through or has come loose. See pic 2. I drew a red line around the subframe.

Let me know what you find.

Hi,

Normally, if you feel it in the seat and pedals, it is related to the rear of the vehicle. If it is in the steering, then it is normally the front. You got both. LOL

Were you able to check the ball joints and other steering/suspension components I mentioned?

Let me know.
