I have a 1998 oldsmobile intrigue. While driving I have a thunking noise and vibration that can be felt through floorboard on drivers side front. While maintaining speed and decelerating the car will wobble from side to side' getting worse the slower the speed. While accelerating all symptoms disappear
Do you
have the same problem?

Check the mounts for the steering gear. Do you have any wobble or vibration in the steering wheel? Next, lift the front end enough to clear the wheels from the ground. Firmly grasp the driver side front wheel and have a helper move the steering wheel slightly back and forth while you try and keep the wheel from turning. Anything more than a couple degrees of steering wheel movement without turning the front wheels means you either have a bad inner tie socket or bad outer tie rod end. Turn the steering wheel all the way to the right and grasp the inside of the bellows boot on the steering rack until you can feel the socket inside. Have a helper move the rear of the tire/wheel in and out while you grip the socket. You should not feel any movement. Next, wrap your hand around the outer tie rod and repeat the process. Again, any movement is bad. Next, grasp the wheel/tire at the top and bottom and try and move the top in and out. There should be no movement. Movement here indicates a bad hub bearing. Next, check the condition of suspension bushings and make sure all nuts and bolts on the suspension, including control arm are tight. If all these check out, place a lever under the tire and have your helper try and move the tire up and down while you watch and feel the lower ball joint. Again, no motion is what you're looking for. While there, check the CV boot for rips or tears. Replace torn/ripped boots. You'll also need to check the passenger side CV(constant velocity) joint. As a last resort, with the car on the ground and the parking brake firmly engaged, lift the hood and start the engine. Have your helper put the car in drive, hold the brake pedal firmly as far down as it will go, and give the car a little gas, accelerating the engine. Observe the engine for any tilting movement. If movement is noticed, shut the engine off and closely inspect the motor mounts for worn pieces.
