banging noise part 2

Re: banging noise part 2

I'll get corrected real quick here and that's OK but it's my understanding we -can- balloon a TC with the kind of torque our motors can make. However if not done correctly it's also my understanding that a front pump in the trans can do the same thing. Something pushed that bearing. You didn't say but I'll bet it was the rear of the thrust that was gone. Meaning it was pushed from the back of the motor.

This happened to me. I sent both the TC and the trans out. Both builders said nope, wasn't their stuff. Hasn't done it since though. :roll:

On reassembly, once the bellhousing is tight, check that you can freely move the TC up to the flex plate. Then you can be pretty sure it wasn't you.

When I took it apart I never actually removed the tv I just pushed it away from the flex plate and left it in. I know when I put it together I had to slide it back up to the flex plate. So I think I did it right the first time. But yea the beari.g was completly gone.

Re: banging noise part 2

the main bearing failure could have been from a ballooned torque converter, the wrong TC bolts being used, lubrication issues - hell it could have been a malfunctioning front drive accessory. The thing that has me wondering is the 'floor moves..." comment. Have you unbolted the flexplate and had a look at the bolt holes? Are they oblong? The one-piece rear main seal has two screws that - if misadjusted - could interfere with the flexplate every time the weight comes around (metallic shavings).

More questions than answers dude...have a good, patient look around

Now, what on the front drive assembly could have done it, I've noticed that my tensioner isn;t very still, but seems to have a wobble or jiggle to it
