I have a older granit BLs...... It makes a little noise when I try to start going if I start slow it ok but if I try to gun it and go hard it makes a noise. I looked at the spur gear and tried to tighten the slipper pad and other suggestions is greatly appreciated!

My Granite BLS does this as well... it's probably just cogging from the two pole sensorless motor at slow speeds. Nothing to worry about. It's annoying at times... but the annoyance causes me to just slam the throttle... and that cures the cogging as well.

Maybe your battery c rating is too low if its 20c or under the motor isnt getting enough juice.
Probavly gear meshing tho. Ill think about it and see if i have another idea

Nope I definetly think it a differential problem. Clutch and mesh look good the only other thing I can think of. I di buy it second hand so there is no telling. I'll bring it to the local hobby shop and see what they ahve to say about it!...... The help guys!

My noob side says replace them all because u probably have a warrenty

My experienced side knows it would probably fix your issue just replacing the one

Ultimatly how long do you wanna wait for free replacment vs. Possibly going to the lhs and picking it up.

don't forget to clean all those gears before it goes back in

I believe stock is 50,000wt i would get 100,000wt and start there.

What's up! @LunchBox did you check all the bearings before you going replacing the hole tranny, and personally that oil diff thing I use regular grease for bearings and if the car or truck is trowing to the side to much I lock the diff so it will run much straighter believe me! The oil diff it's for advertising which is the better diff brand use lucas if u check some come with it.
