I'm sure you've figured this out, but here's the spot. This picture leads me to believe that there is no oil hole so you have to oil the crevice and keep turning the spindle to get it to flow inside. It may take some time. I don't necessarily recommend this because others might yell at me, but I would probably squirt wd40 in there, AFTER wrapping the area and the nozzle/straw in a thick rag to prevent the wd40 from going anywhere else besides that crevice. In addition to degrading rubber, WD40 might harm the clear coat or paint (not sure, it hasn't happened to me yet, but I'm careful not to get it on paint). Others also say it leaves a residue --- I don't know. After WD 40, then oil. But the oil alone should do it. I don't like the smell of WD40, but I sometimes use it because I'm impatient.
