When I accelerate it feels as if my car is being held back or stopping the car from moving. There's a grind sounding noise from the front driver’s side tires, but I've changed the brakes, caliper and rotors. Any insight or help would be greatly appreciated.

Hi,

It does sound like a brake is dragging. After driving, does there seem to be excessive heat coming off the left front wheel? I realize you replaced the caliper and brake components, but it still could be sticking due to other causes.

Do me a favor, first see if there is excessive heat from that wheel after driving. Also, lift the wheel off the ground safely and have a helper apply the brake so you can't move the wheel. Then, have the brake released and see if it turns easily.

Additionally, when it is off the ground, see if there is any play in the wheel bearing. Spin the wheel as well to see if you can duplicate the noise. Also, pay attention to see if there is anything that changes the sound. For example, if you apply the brakes, does the sound change? If you make a sharp right or left turn, does the sound change? Is the vehicle pulling to one side? Anything you can think of, let me know.

Let me know. Also, if it is loud enough for you to record and upload for me to hear, it may help.

Take care,

Joe

Hi,

I have a feeling you have a bad rubber brake hose. It is the one that attaches on the rear of the caliper. Over time, they break down internally. As a result, you are strong enough to push fluid through it to actuate the brake, but when you release pressure from the brake pedal, the caliper isn't strong enough to push the fluid back. That is what can cause them to drag or stay engaged.

The easiest thing to do is have a helper press the brake while you have that wheel in the air. When the brake is released, see if you can turn the wheel. If you can't, open the bleeder on the caliper to see if it releases pressure and allows the wheel to turn easily. If that is what happens, it is most likely the hose.

If you look at the attachments below, they provide the directions specific to your vehicle for replacement.

Let me know if this helps or if you have other questions.

Take care,

Joe

Hi,

The intermediate shaft connects the steering column with the rack and pinion. I have no idea how that would cause a power loss or constant grinding. Has the repair been completed and is the problem gone?

Let me know and thanks for the update.

Hi,

It is the Intermediate steering shaft. I attached the directions for replacement below. Take a look at them and see if you are comfortable doing it. I can help from this end if you run into trouble.

Once you take a look through the directions I provided, I have a feeling you will understand why I don't think it would cause power loss or a constant grinding sound. Usually when the joints go bad, you will hear a clicking sound when turning the steering wheel. I'm not saying it isn't bad, I just don't know how it would affect what you are experiencing.

Let me know.

Take care,
Joe
