I took apart the diffs for the first time on my 18 mt. I greased them according to the instructions and put them back together. Not the wheels dont turn when it on the ground? it it too loose? too tight? this is my first time and Im pretty sure I put i together right but Im not sure what to do. Any help would be great Thanks:thumbsup:

2 questions.1) what kind of grease did you use.and 2) did you make sure to tighten them down all the way and then back them off 1/8 of a turn?

I used associated steal diff lube ( Is said to use in manual.) and stealth black grease ( also according to manual.) I think I got it working. but it seems a little off. It may just be the motor is getting bad ( its like almost half a year old and Overused Majorly lol) . ill bring it to my local hobby store and see if they know how to fix it.

Thx man!

I ran itfor a while and I am noticing some grinding noises and when I spin the wheels by hand it feels like granding... Is it one of the smaller diff balls outof place?
