Hello all...I bought my 2012 FJ on Wednesday and after reading this forum almost all day I was excited to go home and make sure my driveshaft was lubed, since it sounds like it's hit or miss if most shops perform that easy yet critical job.
I had purchased a general automotive grease (#2 NGLI lithium), and one that claimed to be moly-fortified in the description on Amazon ( see here ). My plan was, as prescribed, to use the moly-fort in the slip yoke, and the "general" #2 NGLI lithium in the U-Joint. Well, long story short, if you look at the PHOTO on the link I posted for the moly-fortified, it specifically says, "for universal joint" on the tube. I loaded it in my grease gun and greased all 4 universal joints without a second thought. When I went to load what I assumed was the moly-fortified into my other grease gun, I realized that THAT was the "general" grease.
I think there's about a 50% probability that the amazon description is wrong. The tube SPECIFICALLY says for use in universal joints, and the tube ITSELF does not say anything about moly on it.
JUST IN CASE it actually IS moly-fortified, what should I do? It only took 2 pumps (more like 1.5) before there was a little grease coming out of the u-joint, so it's not like I blasted the thing full of molybdenum. On the other hand, if moly really does cause premature wear of the bearings in the u-joint, I feel I might want to do something about it...but what? Get a non-moly grease and REALLY pump it through there? Or is 1-2 pumps dilute enough that I should be alright?
