Why does my car pull to one side when I accelerate?

Does your car drive straight while cruising, but pull to the left or right when you press the accelerator? Maybe you notice the steering wheel tug in one direction when leaving a stoplight or feel like you have to make a small steering correction during acceleration.

If you’re experiencing a car pulling to one side when accelerating, there are several possible causes.

This is also commonly searched as “car pulls when accelerating,” “steering wheel pulls under acceleration,” “vehicle pulls left or right when accelerating,” “front end pulls on acceleration,” or “why does my car drift when I accelerate.”

At Tim’s Quality Car Care, we see this concern fairly often, and it isn’t one we like to diagnose based on the symptom alone. Suspension, steering, drivetrain, tires, and other components can all affect how your vehicle travels down the road.

Here are a few potential causes we may consider during our inspection.

 

A Worn or Damaged Control Arm Bushing

One possible cause is a severely worn or damaged control arm bushing.

Control arms connect parts of your suspension to the vehicle and allow the suspension to move as you drive. Rubber bushings are commonly used at the mounting points to allow controlled movement while helping isolate vibration and noise.

As these bushings age, the rubber can crack, tear, soften, or separate. A hard impact from a pothole can also cause damage.

 

 

If a control arm bushing becomes severely worn, the control arm may move more than it should. During acceleration, the forces being applied through the drivetrain and suspension can cause the wheel’s position or alignment to change temporarily. You may feel that movement through the steering wheel as the vehicle pulls in one direction.

We see this fairly frequently, particularly on larger front-wheel-drive vehicles.

 

Worn Engine or Transmission Mounts

 

Another possible cause on a front-wheel-drive vehicle is a damaged engine or transmission mount.

Your engine and transmission are attached to the vehicle with mounts designed to hold the drivetrain securely while still isolating vibration.

When you accelerate, the engine and transmission naturally move as torque is applied. Good mounts keep that movement controlled.

If one or more mounts are broken or severely worn, the drivetrain may move excessively during acceleration. On some front-wheel-drive vehicles, that additional movement can contribute to a pulling or steering sensation when you press the accelerator.

You may also notice additional vibration, a clunk when accelerating or shifting, or excessive engine movement.

 

A Steering System Problem

Your vehicle’s steering system can also contribute to a pull during acceleration.

Depending on the vehicle, worn, loose, damaged, or binding components within the rack and pinion or steering linkage can affect how consistently the wheels respond.

If something in the steering system isn’t moving as designed, changes in vehicle load during acceleration may make the problem more noticeable.

Because steering is such an important safety system, this is something we recommend having inspected rather than trying to determine the cause based on feel alone.

 

There Are Other Reasons a Car Can Pull

Control arm bushings, drivetrain mounts, and steering problems are only a few possibilities.

Tires, wheel alignment, suspension geometry, drivetrain characteristics, and other worn or damaged components can create similar symptoms. Some front-wheel-drive vehicles can also exhibit a degree of torque steer, where drivetrain forces influence the steering during harder acceleration. That’s why proper diagnosis matters.

 

Steering and Suspension Checks Are Part of Our Digital Vehicle Inspection

At Tim’s Quality Car Care, one of our core values is paying attention to every detail.

That’s why steering and suspension checks are included as part of our Digital Vehicle Inspection. Our technicians inspect important steering and suspension components and document what we see so you have a better understanding of your vehicle’s condition.

If we find a concern, we’ll explain what’s happening and help you understand your options. Our goal is to give you good information so you can make the right decision for your vehicle and your family.

 

If your Car is pulling, let the mechanics at Tim’s check out your suspension system.
