sorry guys i fell asleep after posting the first part heres the second lol

tail shaft housing might have to removed also then the cross member. never had to do it since most my trucks are 4x4s and the o ring isnt in all trans just a few styles and i only had one of those and it didnt leak.

i dont see why you cant just fill the hole with rtv or something but why even worry about it, i mean if gm thought it wasnt needed then why did they do it? but then why didnt other trans have it?

Just throwing this out there too, to go along with the guys saying just seal up the hole.

When I replaced my engine/transmission a couple of years ago, I went with a TCI Streetrodder transmission. I used my existing yoke, and soon found out about the weep hole.  I contacted TCI about the O-ring, etc., and they told me they didn't build their transmissions to use them at all. Their advice was to seal the hole or get a yoke without the weep hole. Just to simplify everything, I bought a new yoke from TCI that didn't have the weep hole, and all is well.

The weep hole is useless.

Ok, enough goofin off, can a worn yoke cause an intermittent driveline vibration, therefore resulting in that leak? ONLY while under load AND moving i will get a mild vibration (i know, thats all i need right), like this,,,hummm-smooth,,,hummm-smooth,,,hummm-smooth. It is smooth as silk while in park or neutral.  Definitely driveline related. Not to mention, my left exhaust is pressed tight against the frame crossmember, Vile mentioned that a while back.

2 piece drive shaft?

Kill two birds, witness mark the yoke to the u-joint. Pop the driveshaft out (careful not to drop a cap and lose your needle bearings) and clean the yoke with some brake clean. You can put some RTV in the weep hole and it won't drip anymore. Install it 180° from the original position and see if it changes the pitch or speed.

[philo_beddoe]

I think i can do that. Believe it or not, i was able to get my small finger between the u joint and weep hole and press the rtv in the hole, but then had to use a screw driver as a small putty knife, but i sealed it good and neat. No more drip. 

I will still do the 180 degree thing though. Thanks V!

Zieg,,one pc drive shaft.

Zieg,,one pc drive shaft.

Vile beat me too it on the one piece.  Remember just because there seems to be no play in a u-joint it could be dry and starting to go bad.  When you take the shaft out carefully rotate the loose caps and the other ones in the shaft itself

Might be the exhaust, my Jeeps exhaust was contacting the transmission cross member for a while, and under acceleration, or at speeds between 35 and 45mph, it would "hum" off the cross member. I could feel it in the floor as well(Cherokee, unibody)

Can you crow bar the pipe down enough to jam a wooden shim in it to separate it from the frame enough to see if it makes a difference?
