Bad Boy buggy axle noise
 

I am working on a 2006 Bad Boy Buggy. It appears to have Dana-spicer H12 axles front and rear. With Avanced motors front and rear.
The front drive axle whines under acceleration even when jacked up and no load.
I have swapped motors and this isn't the problem
I have changed the differential fluid. This didn't help either.
Anyone have any idea what is causing the whine/roar?

sounds like bad diff. gears. then they wear/go bad they teeth dont line up and you get a wine. Check that the teeth line up EXACTLY correctly. also check to see if they are worn badly or just plain damaged

Re: Bad Boy buggy axle noise
 

The differential gears look okay but I can't really see the gears above that, that connect the motor to the diff gears. Is there a service manual or instructions on how to disassemble these?
Where can I find parts?

Re: Bad Boy buggy axle noise
 

take your motor off and pull the male spline assy out and you will find a bearing behind it all. i just found that on mine and now you cant hear anything

i have taken the motor off but i cannot pull the male spline assy out...is there another step i need to do?

Re: Bad Boy buggy axle noise
 

There should be a snap ring holding it in. Pull the snap ring and it should slide out.

Re: Bad Boy buggy axle noise
 

we pulled that ring out and it still will not slide out??

hey bud. you may need a slide hammer. bad boy buggies are hard to get parts for but in alot of ways very close to most ezgo carts. in my oppinion you may have a bad bearing somewhere in the diff causeing the teeth to not line up exact. did you notice alot of shavings in the diff oil when you changed it?

Re: Bad Boy buggy axle noise
 

it Is hard to pull out but it will come out. Find a ezgo workhorse rear end and use gears out of that to replace your oldr gears

BBB go thru front wheel bearings, like a kid eats candy. check those also.
