Another thought. I had an email notification from the forum today saying that someone had asked a question in this thread about whether it really is important to use two types of grease for the drive shafts. I guess that message has been deleted, but the gist of the message was that the person who posted it had consulted a dealership, who recommended buying one type of synthetic grease and using it in all the fittings (in other words, no need for moly in the sliders).

I disagree. I prefer to stick with what Toyota specified. I don't think the technicians in a Toyota dealership know better than Toyota's engineers. Also, it's tempting for the dealership to save money by standardizing on one grease, even though Toyota specifies two different greases.

As an individual, I don't mind spending time and money using two separate greases in two separate grease guns and doing the job as Toyota recommended. If Toyota issues a service bulletin changing the recommendation, then I'll change how I do the job.
