Any help would be more appreciated than you can imagine.
Good! Knowing it is safe to drive is the most important thing at this point. :)
Thank you, thank you, Freeandfreezing. I really appreciate your advice. I have a back up car that really needs some attention but it’s a good little Nissan. I’ll have the Dodge towed to the dealership unless my neighbor who checks it gives an “OK” to drive it there.
I can’t thank you enough.
One of the big tell tell signs of bearing failure is slight left and right swerves when driving down the road. If the bearing is bad then the noise will usually change when swerving slightly.
Also possible. But most of my clicking wheels have been cv joints.
Thank you, UScbass. I got up under it and checked every single thing I could. Turned the wheels this way and that, revved the engine and checked again and again. Nothing moved ... except my index and middle fingers when I stupidly went to go under the car farther and grabbed the exhaust. Got Burn Jel and Band Aids on. The stupidity hurts most of all. Just wasn’t paying attention.
That rules out a failing CV. Sounds like a failing wheel bearing to me. It is possible that a sticking caliper can cause an intermitted drag feeling after you apply the brakes, but it won't just start when you are driving and then stop.
One other possible source of that kind of behavior is some wire or other junk that got jammed into the caliper housing and is interacting with the brake disk. Uncommon, but it happens sometimes.
Get you car checked out by someone familiar with bearings, disc brakes, etc.
I forgot it was RWD. Like God intended.
You could have loose wheel lug nuts and don’t assume that the tech did not leave a caliper mont bolt or slider bolt loose either.
You should not dive it really.
And if you do take it back, don’t take it to the same shop, if they messed up you are very, very likely not to get the truth about it.
I was a tech before disability, I know.
And yeah all wheel drive CV joints can go out.
Usually they make more noise powering around a corner one way or the other.
It does sound like something with the brakes to me. Especially since there was recent work on them.
If not a loose bolt then I’d guess a missing brake pad clip. Probably the one(s) at the rear of the pad.
Clips are “springs” that are in front and rear of the pad That help keep the pad from “clacking” back and forth.
On hard acceleration the pad would be pushed forward from the friction. In reverse there’s nothing “pushing” the pad forward, (if it’s missing), so no clacking.
Also it should quiet down when actually braking.
“... a sticking caliper can cause an intermitted drag feeling after you apply the brakes, but it won’t just start when you are driving and then stop.”
And that’s exactly what happened today, unfortunately. Driving on a country road back home at 45 mph and the drag/rub lasted about 2 to 3 seconds.
Thank you so much for your advice.
If you don’t have the mechanical skills to have already removed the wheel to have a look, then you are not qualified to fix it anyway!
Take it to the dealer.
Aha. Would that also cause the rub/drag I experienced today, Do_Tar?
Correct, and it will change as the calipers contact the disk (assuming disk brakes), and usually you can feel or hear it if you jack up the wheel and rotate it by hand.
That kind of testing is probably best done by going slowly in an empty road.
Thanks, faucet man. I have a neighbor with mechanical skills who will look at it this weekend.
You just described the rubbing/dragging perfectly, Revel. It, indeed, ever so slightly pull to the right.
Hey let us know what he sees.
That sounds like what a close to failing bearing does. If you are driving along at 45 the brake calipers are not touching the disks. If there is enough friction for you to feel it that means something is not rotating close to properly. In theory it could be some junk touching the tire, or in between the caliper housing and the brake disk, or even between the car and the road but each of those cases except for the junk in between the caliper housing and the brake disk makes a lot of noise when it happens and basically requires you to run over something.
A failing bearing suddenly increases its friction because bits of worn metal are in the grease between the rollers in the bearing and they temporarily stop a part of the bearing from working properly. When that happens the bearing gets hot, and has more damage.
At some point the damage is enough that the bearing stops turning, or generates enough friction that it is like one wheel having the brakes on. At that point you are not going much further, and then you are waiting for a tow truck.
Isn’t the Charger rwd?
Nobody who buys a Dodge actually uses the brakes.
At this point it just needs to be looked at.
After a brake job sometimes calipers will hang up particularly if they are old high milage etc.
If a vehicle has over 100k miles I would always recommend new calipers.
I even knew some techs that would even skimp on lubing the caliper slides.
You just never know.
