repack with synthetic. letting it sit anywhere wins, it may even EAT the first repack, if viscosity hasn't been content anyway (from your description, waiting for the suns seems to have the wax crap invented in the 1800s).I have learned as a service person, ALL oem grease packings are absolutely terrible, and even forgotten (subarus for example had drops of crappy stuff even in awd!)
A personal example of a win for me was grabbing the first top of the line stuff from advanced auto (other brands compete here as well), and it was valvoline synthetic for wheel bearings, cv joints, and if you could pack a grease gun with it, works there too. 420 degrees maximum, funny enough it lubed so good as to not even get warm after high speeds. As lubes and companies all follow rules, any brand labeled synthetic is better than what is oem.
