Dialing my son's Lucky Crew - help please

[somegeek]

This is on a Lucky Crew for my six year old son that rides it a few hours every day since he got it this last summer. I've replaced both the front and rear stock bearings with Red's Bones yesterday. Factory bearing spacers are installed. Axel bolts are tight. I've rebuild the headset so it's like butter. Two brake bolts are tight as well. Still hear a "braagggg" sound from the back end when you drop his scooter on pavement. I used to have it dialed after I replaced bearings the first few times however nothing I've noted above fixes this sound now

Does the seam between the bearing and wheel get worn to create noise? Do the axles eventually need replacing due to wear?

Thanks in advance.

If it's making a "braagggg" sound, then it's most likely the brake. Not sure how the lucky brake system works, but even when the bolts are tight, alot of brakes will still make a noise just because it's metal on metal. The solution is just to place a piece of rubber in between the deck and the brake to soften the vibration. I've found a bike inner tube works really well. Just cut out a piece out of an old one and that should do the trick.

Go to your local hardware store and buy a neoprene washer (look like this)

Then just place it between the brake and the deck and tighten everything like you normally would. I'm not completely familiar with how luckys brake system work because I no longer buy parts made in china...but this method should work. If there happens to be 2 brake holes side by side/horizontal then id suggest using the same method with the neoprene washer but just make some "make-shift holes" so that the 2 bolts can fit through the washer.

That would be the brake vibrating. If it's like a flex fender or whatever they are called these days there isn't a great deal you can do about it. Naturally the metal softens up over time and whenever you drop the scooter it just vibrates and makes a noise. I'd pull the brake off and stick some sort of rubber or synthetic washer between the metal-to-metal part of it's fixing location. Might dampen some of the vibration.

Also you should never have to replace an axle. They don't even snap unless you ride hard on them loose. Brakes are the hardest part to dial and always have been, many a scooter has been thrown in anger due to rattling or otherwise noisy brakes being untameable.

If it doesn't have an impact on how it feels to ride I wouldn't even worry about it. Contrary to skate rat theory the biggest dick does not belong to he who has a scooter that bounces like a basketball.

edit: I'm not familiar with any of the new products however I had a quick look at the lucky crew and it appears to be a more traditional solid brake w/ spring. If it is see if you can lift the spring on the deck side with a flathead screwdriver and get a penny or something underneath it. Used to work on razor pros.

Thanks for the replies. I think it's his rear wheel as the sound followed it when I moved it to the front of his scooter. The bearing almost drops into place when inserted on one side. Think that wheel needs replacing to get rid of the sound... but that's it. Not a deal breaker.

Noted on the basketball reference. There's a kid at our local spot that is probably one of the best kids on a scooter at his age there and his scooter is noisy. Doesn't slow him down or hinder him.

If the bearing can be easily inserted into the wheel core it means the wheels is "ovalized". This is caused from riding with your wheel loose or not tightened for a period of time. Its actually an easy fix.

Ive personally never used a cut piece of soda can(as seen in the video) in all of my 6 years of riding. I found the easiest way to do it is use the same method except put duct tape around the bearings then re-insert hem. Its always worked for me.

Yeah if it's the wheel causing the problem don't throw it out. I used to just use masking tape, you can use anything you want. Just make sure the bearing sits in the slot nice and tight.
