Re: What is this awful noise?

Here are some notes on this issue.

1. Noise started with no warning. Basically, one day it was is was there.
2. Sound came straight out of the oil pan.
3. Did not get louder when pulling the Flex Plate Inspection Plate.
4. Sound would go away when applying Brake and Gas while stopped in Gear at around 1100rpm.
5. Sound was present when cold or hot.
6. Sound was present when in gear or not in gear.

Tips on pulling:
1. Don't have to pull the trans out of the vehicle. Just have to get it back around 6 inches.
2. Don't have to pull the transfer case.
3. Get yourself a trans jack. Safer.
4. Drain TC and Trans fluid.
5. Tie your drive shafts up out of the way. You don't have to remove from the axle end.
6. Disconnect your rear exhaust hangers so it can move free.
7. Disconnect exhaust from header
8. Get an E12 Socket
9. Pull CPS so you don't damage when you separate trans from engine.
10. Expect it to take 2x as long as you think.

This is just getting things apart. I'll add more tips as I put it back together.

Re: What is this awful noise?

Ok... back in business and running quiet now.

Some notes on the install:

1. Don't get in hurry and throw the new flexplate on. Don't forget to put the shield on first.

2. Use 3 jacks. One for engine, one for trans and one on the transfer case. It helped a lot to get things aligned up just right.

3. Have a helper when you are torquing the flexplate to crankshaft bolts. 105ft/lbs They can hold the bolt on harmonic balancer while you torque. They come in handy when putting the flexplate to torque converter bolts in as well.

4. Put all TC to Flexplate bolts on first. Then get the bolts aligned in center of bolt hole and tighten. Have your helper turn the engine over by hand and then pull each one and apply blue loctite. put on and tighten. Turn and repeat till all are done. Then do the final torque. Goes a lot faster having a helper.

5. Super long extensions for the top motor bolts. The E12 bolts were very easy to get tight when the trans is tilted down and a long extension.

6. Don't forget to refill your transfer case and transmission fluid.

I think that was it... the engine and trans went together with no issue and the rest was just taking time to make sure I didn't rush and miss something.
