4 T45 e transmission the axles are all fine making a loud popping noise sounds like it's coming from inside your transmission when you accelerate any ideals

 

There is a drive chain inside, but I have never seen one jump. Are your axles new?

 

Pulled both axles in great shape no slack no showings of wear

 

Axles are inexpensive and transmissions are not. 90% chance of any noise up front being from the axles in my opinion.

 

I agree with Andy. I'm not a professional mechanic, but in my 45+ years of working on my own cars, the popping has usually been an axle. What do you hear if you do figure 8's in the car? Any popping or clicking is an axle.
