  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!

Let’s hope your not trying to steer into a corner sharply you’ll loose control the sway bar dose exactly what’s its name keeps the car from swaying to far to one side. Every time you turn sharply at speed the bar will twist and pull the other tire in the opposite direction keeping the car firmly planted on the road so you don’t loose traction

Not a bad idea while replacing one to do both, as they're the same age, so why not double down?
Not saying this theory applies to all suspension parts, but most except for CV Axles unless you really have money to burn!
Love your Instructionals!

So random question since I'm here does anyone at all trust plastic sway bar end links or should I invest in some aftermarket metal ones. It's on a jeep renegade

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!
