first of all, why do you want to lock it? the only reason i can think of is if youre going to be rock climbing but a rustler isnt ment for that. i would just leave it how it is unless it absolutly necesary but remember that it puts a ton of strain on the drive shafts and tranny.
im experimenting with different things. this is my first hobby-level rc car. my radioshacker didnt have any configurable or adjustable stuff on it. i guess i dont want to lock it completely, but use a lesser dense grease, because if one tire leaves the ground, all power goes to that tire and i have to go push it off the obstacle or else it wont move.
