New to crawlers - Gen 7 Pro noise?

[Roty]

I have recently dipped into the crawler world, more specifically this is actually my first venture into the hobby grade R/C world. I have watched lots of scale crawling videos and it has been a strong interest for quite some time. I purchased myself a Redcat Gen 7 Pro and my son a Gen 7 Sport. We both love the crawlers and have been driving them locally in parks, campsites, etc.

I have noticed since that I have been using my Gen 7 Pro that it has developed a clicking noise from the passenger side back wheel/tire. I have a recorded a video of this and I will put the link below. I have had the truck maybe 4-5 months and it has not been abused. Its hard to tell where the issue exists from the audio in the video alone but in person my son and myself both concluded that the sound was very prominent from that side. I am not sure if its coming from the axle or the differential. Anyway, I want to fix the problem and I am not afraid to take the truck apart. I am looking for some advice and guidance in which direction to go first. Thank you for your time!

Welcome to the hobby! It definitely sounds like there is something binding/rubbing. I've had plenty of weird noises that went away after a nice cleaning and lubrication of all moving parts. I would start off by pulling of the rear axle, check for no cracks or obvious issues, and then cleaning out the old grease, blast the bearings with cleaner and regrease everything. That's definitely a good place to start, at least in my experience. Good luck!

Thanks for the advice! I will do that and see what I find.

The other thing to check while you have axle off is that the plastic locker didn't strip out or crack. Both of my boys had that happen. If it did, replace it with the solid aluminum hsp 180009. It is a direct fit replacement that even uses your same bearings. Cheap at around 10. Best upgrade.

If you start doing more crawling instead of trails a cheap 27t to 35t motor will make it more controllable for the slow crawling stuff.

Welcome to the redcat addiction and have fun.
