One grease for wheel bearings and suspension bushings?

I know I'm probably way overthinking this, but I'm trying to decide on one grease to use for a couple different purposes. The main purpose is for trailer wheel bearings. I have both a boat and a utility type trailer for towing a side by side. The majority of towing of the utility trailer is at highway speeds a couple hundred miles at a time. I guess having a failure, and having the wheel w/ hub pass you going 65+ will make you overthink it a bit. (The failure was not due to type of grease) I also use the grease gun to lube various parts on the SxS like suspension bushings etc. Currently have "Green Grease" in the gun. Looking at that, Redline CV-2, or something from Schaeffer or Amsoil. I used to use M1, but I keep the grease gun in the shed, and as noted, M1 leaks a lot.
 
I have 2 grease guns. 1 loaded with SuperTech Marine wheel bearing grease for both my boat and untility trailers. The 2nd with chassis grease for the truck suspension. I suppose you could cover all those applications with the marine wheel bearing grease.
 
Hah I am not alone. I have been silently overthinking grease for months. Marine grease sounds excellent for many things and almost invested in a bit but because i'm a cheap-sake havent seen any that met my cheap-skate price.

My conclusion was when reading about what great is for what, they all seem to universally work for many things. The main thing to watch for is mixing different types of greases that use thickeners that are incompatible with others. https://www.machinerylubrication.com/Read/1865/grease-compatibility

I personally settled on tubes of hi temp red and delvac commercial heavy duty that was cheap from blanes black friday sale. I plan on occasionally loading brush into large fires so a high dropping point was important to me.

Not only can you have incompatibility with thickeners. There can also be incompatibility with base fluids, additives and proportons of grease blends. It's really an issue of grease incompatibility. Never assume that thickener compatibility charts are correct. Often they're wrong or even contradict each other.
 
Many bushings are supposed to be dry. If you prefer to lubricate, use only a silicone based grease which is different than wheel bearing grease.
 
Castrol pyroplex blue.

Best to split it up.
Mobil centaur Moly for things that slide
Castrol pyroplex blue for bearings.

My favorites at the moment.
 
I used WD-40 Specialist calcium sulfonate grease for almost everything. Since HD doesn’t stock it anymore, I have Blaster’s equivalent. The jury is out.
 
I'll second Schaeffer 219 Synforce Green. I have it in multiple wheel bearings and hundreds of other fittings between our farm and trucking equipment. We are also migrating to it at work in all kinds of industrial equipment. IMO, it's about the closest thing to a "one size fits all" grease on the market today. At least for general automotive and industrial use that is.
 
Marine grease for the boat trailer and outboard fittings.........high temp red on everything else - mowers, auto, tractor etc....
 
Like another guy said, I also have Supertech marine grease in one grease gun, I use that for less important stuff I don't want to waste good/expensive grease on, it's pretty good for how cheap it is and probably the best of the lithium complex greases I have used over the years. I use it mostly on yard equipment which is subject to a lot of moisture and water, does fine for that. For tie rods, ball joints, kingpins and other suspension bushings I've become very fond of the Schaeffer 274. I've recently been doing a lot of suspension work and taken several brand-new tie rods and ball joints that were extremely hard to move by hand out of the box and they all have had this cheap looking yellow grease in them. Greasing them in the bench vise, working the joints around a lot, greasing them some more to the point I get grease coming out all around the joint, the joints now move firm but smoothly on all of them and the grease starts plating to the ball/socket very fast and doesn't get wiped off after it sweeps through the socket I noticed. I first decided to try this grease after I did the kingpins on my truck. I've used all kinds of lithium complex greases in the kingpins over the past 12 years, but after I re did the kingpins almost 2 years ago I used the Supertech marine grease in them initially, seems the lithium grease would get pounded out every few months and a lot of water would get purged out during the rainy season, so I tried the Aluminum complex 274 grease. Not only does it stay in the kingpins and tie rods twice as long, but there was also a very noticeable reduction in steering effort and steering smoothness, which is very welcome on that thing.
