A few grease questions (2 Viewers)

[Hatsuwr]

Curious what other people are using in these locations. Here's what I have:

Driveshaft slip yokes:
Valvoline synthetic #2 lithium complex, ~5% moly-fortified

Driveshaft U-joints:
Valvoline synthetic #2 lithium complex, ~5% moly-fortified

Steering knuckle bushing:
Mobil Delvac Xtreme #1 lithium complex, ~3% moly-fortified

Steering knuckle needle bearing:
Mobil Delvac Xtreme #1 lithium complex, ~3% moly-fortified

Wheel bearings:
Timken wheel bearing grease

I’m using Lucas Red and Tacky for everything.

You shouldn't be using moly grease in the NRB's in the u-joints. They are seeing a lot of acceleration on every shaft rotation and the moly grease is better at low speeds.

otherwise, anygrease is better than no grease. I tend to go red n tacky or green HD in anything with a zerk fitting and then my wheel bearings get mobil 1 full synthetic grease.

edit: u-joints

I use Mobil 1 chassis grease in all. KISS!

As a general rule, we do not use moly in high speed bearings (needle, wheel, spiders (AKA U-joints).

Moly in propeller shaft slip yokes are fine and recommended. But I just add moly, in those few, that clunk after lube with Mobil 1. I keep a tube of #1 w/moly for those. I the idea behind moly in these, is to reduce stiction. I do not typically see that as issue, in our 100 series.

I have consider switch grease for the axle needle bearing and bushing. Why: The tendency of Mobil 1 to have a small amount of separations of its oil from grease base/thickener. We see this in leakage from tube on the shelf, or oil in bottom of a tub of mobil 1.

Unfortunately all oils will separate from their thickener. Some quicker than others, but they’ll all do it. 5 years of shelf life is the rule of thumb for grease.

Good to know, I have some old grease around for sure.

Are you talking about the NRBs in the steering knuckles? Makes sense to avoid moly there. Main reason for moly was the bushing right next to it, and I figured the grease was going to migrate anyway. But I did throw together a short list of #1 moly-free greases. Emailed those companies to see if they could fill in some of the gaps in the specs.

I have a list of greases above that might be good candidates for you to try for the steering knuckle bearings/bushings. They all come in NLGI #1 as recommended by the service manual. I didn't include separation since it wasn't commonly mentioned, but Cerulean has a mass loss during storage of <6% (ASTM D1742) and Paragon 3000 shows 0%, which is interesting. I want to try the Paragon, so I hope they get back to me about that missing info.

Regarding the u-joint spiders, I thought moly was ok there because of their oscillating motion, but now I'm starting to question that.

Alright, I picked up TRC Paragon 3000 #1 and Amsoil Synthetic Polymeric Truck #1 and will use one in each steering knuckle. Also got some Paragon 3000 #2 and Amsoil Multi-Purpose #2 and will use one on each side's wheel bearings. I'll give it at least 10k miles then pull everything out to compare.
