Any advice. I have XT cranks with octalink BB. I greased the cup threads first, then tried teflon pipe tape as per "Nate Speed Hub" But the thread tape came off as I turned the BB into the shell. What about that removeable threadlock stuff. I'm pretty sure my cranks arms are tight enough, I'm using a torque wrench to 35 ft lbs.

Thanks for any input.

If you apply the tape in one direction (clockwise vs counterclockwise) and the tape comes off when you screw in the cup, apply the tape in the other direction. It matters which direction the end of the tape faces.

I also used silicone in a tube to eliminate the BB as the source of a creak. It ended up being my cable stops. As the suspension moved the housing ends would move in the stops and make a noise. I just use lots of grease in the BB and on the cups. Sometimes it is hard to figure out what is actually causing the problem. I've had a seat and a seatpost also causing noise.

What pedals are you using? Shimano pedal needed rebuilt once with grease
I'm using 959's. I'll take a look at them. I have a new set of 515's I'll throw on to see if I still get the creak. Thanks

Thanks for the tip, I'll try the tape in opposite direction.

Silicone in tube? Are you referring to silicone sealant? The stuff that stays pliable after it dries?

Thanks for the reply.

Could also be the crankarms where they are pressed into the spider for the chainrings. Sometimes dripping loctite into both sides of that area will help.
