I had my left crank arm get loose due to it getting mangled where it connects on to the main bearing. I had tried just tightening it down as well as using Loctite on it to hold it in but it was better to repair it by replacing it with a new one (it has been great ever since). I wanted to share how easy it is to do this repair yourself as this can be a common repair on bicycles and e-bikes (like my Qualisports Dolphin you see in this video (video review here: • Qualisports Dolphin Fo... )

    @@EricDIY Nice video. I have this exact same problem with an E-bike. I realize that this problem grows much worse when you bike with it being loose. You need to fasten the nut tightly immediately at the very first moment you notice it being loose or you end up having to replace the arm.

    Thank you for this video! Your video confirmed for me that I had a wallowed crank arm. I had tightened the mounting bolt with gracious torque once I discovered the bolt was not torqued well. This almost got rid of the popping (knocking), but not quite. Because I bought the e-bike in February, I called the company for support under warranty. They have sent out to me a new crank set. No squabble at all.

    Appreciate the video - and the time and effort it took to make. Saved me and I'm sure other people even more time and effort even money- trying to fix my own/their bikes. RN my bike IS my transportation as I await fixing my jeep. So my livelihood depends on it. xo

    Best way to remove a Crank Arm without the "Special tool" is to use a open end wrench (None Adjustable). Slide behind Crank and pull wrench outwards gently. Do this in a few spots and she should pop right off after a little Mucsle Power is applied 💪🤟

    Thanks I took it to the local bike shop and he said it looks like it needs replacing but since he didn’t have the part in stock he tightened it. The squeaking was even worse the next day but today it’s gone. Thank at least I know what the fix will be if it returns.

    Get a new bolt and replace it. If it has a derailleur, make sure it is adjusted properly. If the crank arm is loose after replacing the bolt, try replacing the crank arm.

    If the square is rouding, buy a new crank arm like I did here. If rounded, it's past repair and you need to replace it.

    Take it off and see if anything is broken where it attaches. It could also be the bearing inside being broken.

    Probably have to get the bearing replaced if it's not the arm. $160 sounds about right. As far as doing it yourself, there are videos on KZread but you also need some tools to push the bearing out.

    If the arm is damaged like I showed in the video, I would replace it. If it hasn't started to warp yet, you might get away with the old one. If it is warped, it will most likely keep becoming loose.
