This is pretty helpful. I have an inconsistent knock sound coming from the engine bay somewhere. Mechanic couldn't identify it and it's not entirely consistent with any specific activity. Sometimes driving over bumpy road will generate it, other times just turning will. It's low frequency in occurrence. This video is helpful since I'm guessing it's a suspension component somewhere or possibly sub-frame bolts. Maybe a video on how feasible it is for a DIY driver to install a camera or microphone in the engine bay to generate data for review? I think if I could replicate the sound for a mechanic, it would help them. Thanks for the video!

[@morpheus232001]

It's very useful and the way you formatted it made it very clear. Coincidentally I'm dealing with some odd knocks right now so this video is right on spot.

Thanks. There are some shots showing pry bar making some movement- is ANY movement unacceptable? Not sure what is an acceptable amount of movement

Thank you for sharing your opinion!

[@matshansson2020]

Very good video, especially the description of how to diagnose the various sources of error! Please post more! However, the video would be even better without the music. It serves no function, but only makes it difficult to hear what is being said and above all how the various knocking sounds sound.

Yeah.

[@AT-wl9yq]

A couple of additional comments. When it comes to front end parts like tie rods and ball joints, you typically won't hear or feel anything when they start to go bad, even it there's some play. These are two of the worst things that can break on a vehicle when you're driving. They need to be checked on a regular basis even if there are no drivability issues. Also, your method of checking the ball joints isn't quite right. When a ball joint starts to go bad, the play is up and down. You check by jacking the car up and getting the wheels a few inches off the ground. You then put a pry bar under the tires and pry upwards. In the video, you put the pry bar in between the ball joint and control arm, and pulled down. You have to go the other way because the springs are already putting a great deal of downward force on the ball joint. Going upward relieves the tension and allows you to see the play. If the ball joint gets to be so bad to where you can see the play by just putting your hands on the wheel and move it without the help of a pry bar, it should have already broken. I'm going into a lot of detail here because when a ball joint or tie rod actually breaks, you instantly lose both your steering and brakes. You have absolutely no control over the vehicle.

[@swmovan]

I had a lower ball joint come apart on my van, many years back. Luckily, I was in the outside lane, and right at the drive to a motel. Just enough time to get off the highway, and out of the way of traffic.

[@jasperbarlow2582]

Spot on there, take note of these comments.

[@jonot8547]

I understand losing steering but how do you lose brakes? Just curious as it's a separate connection

[@brittanylee2163]

My wheel fell down after ball joint broke on the side of road in front of a Firestone tire shop. No symptoms that I could tell prior but this was many years ago on an old Dodge minivan. Issue I have now on a Ford Taurus is that rubber squeaking noise when turning wheel or going over bumps at a slow speed. Gonna bring car in to be fixed asap

[@wrblue08]

Superb video. Not a single reason blamed on the actual strut, unlike some mechanics who want to grab a quick big buck from the job and parts.

[@autodocuk]

We are glad that this video was useful to you!

[@valkman761]

How naive. As a mechanic I've seem numerous struts with a play in it. I've also seen people who've changed the wheel bearings due to a strut play.

[@AT-wl9yq]

@@valkman761 How do you check to see if a strut has play?

[@valkman761]

@@AT-wl9yq While having the wheel jacked up and strut extended, grab the tire in 12 and 6 o'clock positions and pull/push alternatively with your hands. This should reveal a strut with play in it.

[@AT-wl9yq]

@@valkman761 I think you may be confusing another type of issue with a strut problem. The strut housing is a solid piece of metal. It doesn't connect to a vehicle in a way that would be possible for any type of play to occur. You may be thinking of the top strut plate/bearing, that can wear out over time. But even with that, you wouldn't diagnose it by checking for play at the wheel. There's always tension on it even when you lift the wheels off the ground. If you do a little research on the issue, you'll find many ways to check for a bad strut. What you're suggesting with play when you move the wheel in not one of them. Its practically impossible. Or, you could be talking about something else and this is just a miscommunication.

[@YAVORKAMENOV]

Very useful video. Thank you ! Only you should mention the steering rack.

[@autodocuk]

Thanks for the feedback. We are glad that you liked our video. We are sure that your comment will be useful for many of our viewers.

[@AT-wl9yq]

From a safety standpoint, the tie rod ends are what matters the most on the rack. Other issues involving the rack are probably not going to manifest themselves in the form of a knock. If its a late model vehicle, you'll probably have some DTC's present that will point to the rack having issues.

[@agunslinger9349]

Always good content. Suggestion. On this one it is unclear weather you are displaying a good part or a bad part when applying crowbar to the part.

If the knocking noise doesn't come out when steering but only when driving over the bump or uneven road, is that still related to the strut mount?

ive changed the axels, sway bar links, control arms, struts and strut mounts. ( im on the second struts and 3rd strut mounts form the dealer) Still crackling, rusty and grinding noise coming from the front end as i go over small bumps. Its like something is dried up. When the strut mount has been replaced it would stop then start again in a few months. Stop doing it when its muggy out, then start again when its sunny. its been like this since 2018. everything i mentioned has been replaced within the past 6 months. Still hasnt gone away.

I have a Mitsubishi Galant that I've virtually replaced the whole front end on. New quick struts, lower control arm with ball joint, inner/outer tie rods, sway bar links. Still have an occasional pop when turning and also have what sounds like a single metallic clicking or popping noise when hitting a pothole or a good dip in the road or even sometimes when the suspension shifts or just backing up slowly. Everything appears to be tight.....
