Clueless...
My brother's Tmaxx 3.3's front left outdrive yoke connected to the front dif broke and when you throttle the engine races and the vehicle doesn't move after I disconnected the front left drive shaft. What could be wrong?

<p class="MsoNormal" style="MARGIN: 0in 0in 0pt"><span style="FONT-FAMILY: Arial; FONT-SIZE: 9pt">Well, since you disconnected the front wheel drive the problem is from the tranny back to the rear wheels (assuming the clutch bell is turning the spur gear).
Process of elimination will find the problem. </span></p>

I think disconnecting the drive from the left front is unloading all the power. kind of like doing a 360 and the inside front tire comes off the ground and spins so hard it turns the tire into a pizza cutter. providing its an open diff and not a locked diff.

<div style="margin: 0in 0in 0pt"><span style="font-size: 9pt">Yes the 3.3 has an open diff in the stock setup. Once either side of the diff is disconnected either by a break or removal of the wheel shaft no power is sent to the opposite side.
But…The 3.3 TMaxx is 4 wheel drive and if it is not moving there is an issue from the tranny back.</span></div>

Also, all the difs work properly by hand. When I turn the rear wheels forward, the front wheel and the rod from where the yoke connects spins the same way too.

Pull the front drive shaft so no power goes to front end. I broke a rear axle and truck wouldn't go till I puled the rear drive shaft. Drove it around that day on front wheel drive till I got home and replaced rear axle.
