I've had a problem with my nero big rock since day one with my diff servo, I went onto the discord and asked around and they told me to post here. So my rear diff is making a high pitched hissing sound when engaged and the rear diff won't lock. I took the rear diff apart to see if anything was wrong, nothing was off. I engaged the servo and no noise occured, even the diff locked. However, when I put the thing back together, the problem returned. If you want to add me on discord, I can send you a video of the problem.
Thank you for your time

Do you think that debris has gotten into the diff? Or something else, I'll have to open the diff up again anyway.

This has happened to my br because of changing the diff brain settings whilst at a decent speed,its best to change at a slow crawl so it locks into place easily,if u stop and it's not lined up its puts the servo under too much stress trying to line up something what's not there,same at speed,best to get another and refit they're not expensive,hope my ramble helps.

This how I lock/unlock my diffs as well, at a very slow crawl. Been working flawlessly so far.
