  7. Knocking Noise Under Your

Shop for New Auto Parts at 1AAuto.com

Is there a knocking noise happening under your car or truck more than just when you hit bumps? Usually the fist thought is a strut or spring, but sometimes it’s the sway bar link! In this video, Sue points out how and why a sway bar link might break and what kind of problems it can cause! Sway bar links connect the sway bar, or anti-roll bar, to some other suspension component, like a strut or control arm. These links usually have a swivel joint so that they can move with the articulation of your vehicle’s suspension. Over time the joint can wear down and break, leaving the bar of the link swinging free to clunk and bang on all sorts of things! While it may seem like a simple problem that you can put off, there is real potential for damage, so make sure to give this one your attention as soon as you can!

Если у тебя с авто произошла такая поломка, значит ты совсем не чувствуешь своё авто.... продай машину, так как не твоё это.... Ты и авто опасны для других участников движения!!!!

Wouldn't it have been easier to just unbolt the broken link instead of cutting it ??

This was incredible to watch, I’m beyond impressed. I’m hoping the author or someone else can respond…I’ve got a 10 year old Acura that has begun knocking crazy bad over the last 2 weeks. Took to my mechanic n mentioned sway bar link (same clunking noise as once before when he replaced on R front several years ago). He took a brief look w wheels turned and said they seemed ok but I can order along w strut mounts. I’m waiting for the parts and driving lightly around town today, my brake sensor went off. My mechanic originally said oh it’s ok to keep driving, but w this brake thing now I’m concerned since the video mentions the link can hit and damage the brake or ABS line.
Should I cease driving completely till I get the parts or am I ok ti drive a bit here n there in the meantime??
Many thanks in advance!

That knocking under my Prius gen 2 should be the steering system with issue. Anyone had the same issue?

This is by far, the best sway bar vid I've watched. And the best part is, it's a female 🙌🙌 The before and afters, showing us what it looks like while the car is moving, and explaining how the ball joint actually works was really easy to understand.
I was going to pay my mechanic to replace ours but I'm going to give it a go after watching this. She made it look easy peasy, you go girrrrrl

I’m hearing a knock when I hit a bump. It’s on driver side. It has to do with me changing my axle. Never heard it until then

I just started hearing a sound like metal banging together, possibly coming from under the engine area. I have an 08 civic lx. I keep seeing this clunking noise that could be the sway links bit it isn't a knocking more so metal hitting other pieces of metal. Any ideas???

I still don’t know what’s knocking under my car but I’ve watched about 4 hours worth of your guys videos so I’m sure I’ll find it when I jack the car up

So that ticking sound at the start is that the sound? I have a 09 pathfinder that when accelerating or more or less maintaining speed. Usually when it’s at 1-1.1k rpm it makes a ticking sound like what’s in the video. Also just had my timing chain redone etc from a reputable mech. But just can’t figure out what the noise is.

My sway bar snapped while I was driving. As I tried to reverse, my rear tyre, I think the suspension too, bent inwards. What do you think could be the problem? Thanks

Very good and well presented video. It's strange how in my Mazda 3 it sounded like it was coming from the rear end, but it was the actual link. Was a quick n easy 15 minutes fix. $32.00 Canadian for the part

I have never been able to tell a difference with or without a sway bar on any vehicle. Though I upgrade from the junk factory suspension the day I buy my vehicles.
