Default Front Axle problem

I have a Berg I recently ran it and there was a new whining coming from the front axle. I pulled the motor out and it only happens when the motor is in the trans housing. Inside the housing there are a couple of small surface rust spots and my short shaft key is twisted. I am asking two questions what you think is wrong with it and do you think because of the twist it could cause horizontal pressure on the inside barring on the short shaft?

When you say it only happens with the motor installed do you mean that with the case split and the motor removed that it doesn't make noise or have you removed the motor and completely reassembled the axle to test it?

I am saying that it makes the noise when the motor is in and dosen't when the case is cracked and gears removed. Also it did not make the sound before the bath at the zoo.

I'd leave the motor off and the gears in and reassemble the case...spin the wheels and take parts off until you figure out what's causing it. If it doesn't make the noise with the motor out...well then you've probably just got some trash or a bad bearing in the motor.

That short shaft needs to be replaced ASAP. Highlandcrawler is the one that made it I'm pretty sure, but he's been hard to get in touch with from what I understand. Super 300s would be your best bet, but they're not available right now either.

Front long side axle is bent after the nuckle berring. Cant tell if the noise is on the gears, bushings, or in the axle berrings. To change to 300's do I need difrent nuckles, c's and berrings?

You're right...I mentioned the highland shafts and completely forgot about them using the Axial outers...good catch I'm on a roll with forgetting details here recently...

This may sounds stupid but take a look at the back of the gear door. Your pinion might be sticking out just enough to hit the door. At least that is what mine did.

well if it took a bath....
i would start by cleanning out the motors and lubing the bearings......
all the knuckle bearings also.........
make sure the locker is tight to the 4th gear.. (That brand of lockers are known to come loose)

What would you all suggest if I said I was going to change to knuckle weights instead of the wheel weights? Do I need to change my nuckles and c's for that?
