Default Yeti front diff rebuild!!!

Alright my racer friends and off-road racing guys I've got a question for you.... Roasted my front gear set in the yeti after the last race and my question is what's you preferred front gear set... Standard, under, or over for racing... My yeti has stock hd beveled gears in the rear and I've heard of people talking about running overdrive in the front but with my automotive background that just doesn't seem right knowing most awd systems have more of a rear axle distribution to allow the vehicle to push the rear through cornering situations...what are your opinions in the rc world and u4 racing situation... any insight would be great thanks...

I am wondering the same thing as well, I have some old open diff gears from the old ax10 I plan on running....I might run the front open and the rear locked....with hardened gears no UD or OD.

I am thinking to run open diff in the front thinking when you jump and land on the front end it will put a lot of pressure on the front end when it fully compresses and full power is applied.

BTW, I love when you truck gives you free machining! :)

HD in the front and UD in the rear is what a lot of the serious U4 guys are running. It keeps the rear from sliding out or trying to pass the front when coming out of the corners.

^^^What Devlin said is correct and its what I also run in my Yeti, it helps with being able to turn better. DO NOT use the overdrive gears in racing as the mesh on those isnt the greatest to begin with. Justin can get away with standard gears because he's solid axle and wont have any problem with getting a lot of steering.
