Oil drips from steering parts?

[booster]

I have been getting random oil drips on the garage floor, mostly from the old Buick but also from the Chevie van. Of course they seem to come from places I can't see well and come and go, sometimes leaving drips on the frame also.

I finally figured out that the oil is coming out of the greased steering joints on both of the vehicles. The grease itself seems to be separating, with nearly clean oil dripping out, even with moly grease. You always will get a little grease bleed out after greasing, but this happens weeks after the greasing, usually. I am using Fleet Farm moly chassis grease, as I have for many years, and this seems to be within the last 2 years or so. Maybe they changed it? I would hate to use expensive Amsoil or Royal Purple grease on the chassis parts, as it hasn't been needed in the past.

Anybody else seeing anything like this?

I'll keep an eye on mine. Could it be the mix of different grease? Mine would have at least 3 different greases by now. Mostly the new stuff comes out but some parts still have an old style looking grease coming out when new goes in.

I always use a hi-temp grease- like wheel bearing.

Living in PHX where my garage temps can get upwards of 140º I see interesting effects on fluids etc stored in the garage.

one which really came home this year was using vaseline to lube seals in the rv toilet...it works great in the winter, but under heat it liquifies and runs away. plumbers grease is rated to 180º- so better for me.

leaks can be tricky as fluids flow to the low parts before dripping, and when driving can be blown all over the place.

1 trick to track leaks is to spray the suspect area with 99¢ store spray on foot powder- the source of a seep/leak will wash away the powder
