Finally riding a big boys bike
Might be less hassle to just tear it all apart and check everything over, oil the chain and will probably fix the problem or you'll find it.

I replaced the BB bearings with new #66's.
Fresh grease, cleaned the cups. It makes almost constant noise pedaling uphill under load. Anybody have any tips?
'36 Rollfast.
I thought I had same problem w/my late 80's Schwinn World Sport. Checked it out. Smooth action. Turned out it was the pedal bearings making the noise.

Sounds more like the pedals making the noise have seen that before.
YES,I had a squeak that I could not find...it was the peddle bearings...only under torque, try taking your foot off each peddle while peddling with only one foot and see if it goes away, that's how I found my squeak. I thought for sure the sound was coming from he bottom bearings. Also as mentioned the chain...I just replaced my mountain bike chain, bike guy measured with a gauge and he said it should be replaced at 90, mine was 190!..bike is 3 years old but ride everyday, even in winter.

I tried new pedals, but no success. I'm still thinking it's the BB. I replaced the rear rim and cog/brake assembly. Now it could be a stretched chain I guess.

Not so sure a bad chain and ring interface will "creak" as Ian claims, especially if slobbered with oil. Worn chains "grind"& "groan" & "snap", not "creak". Did you do the "touch" test yet to more closely locate the noise? If not, why not? Metal Interface NOT chain related I would bet on it. Did you do the WD40/PBb test yet? If not why not? C'mon may, it cannot be this hard!(twss)🤣

Haha! I haven't even gotten close to any of my rides in a while. I'm gonna hit the BB and any questionable areas with WD and see what transpires. This particular one may just turn into a late summer/early fall project.

Never ever squirt WD-40 on greased or oiled moving parts unless you're cleaning them.
