What zerk fitting is this?

It’s on my universal joints.

 

Also, how much grease should be pumped in them. I grease electrical motor bearings at work but not sure about these.

 

It's it just me? I don't see a zerk fitting

Pump until grease comes out.

 

I don’t see one either.

The brass colored area doesn't look like a zerk.

 

First. That is what Toyota refers "Double carden joint." I just always refer to them as a "U joint." I also can't tell if it's a true zerk fitting. I understand that starting in 2018 Mama Toyota no longer has factory zerks on the driveline.

On any driveline U joint you want to pump grease until you hear it "popping" as it comes out around the seal. So you need a quiet atmosphere. And wipe off the excess. That shit will fling and make a mess.

 

Yeah, those are called "flush type" grease fittings. A mess to lubricate them with the needle adapter and most of the time they are included in aftermarket parts. Designed for areas where clearance is an issue. I rarely see them used where this would apply so I tend to think part manufacturers are just being cheap.

Great info! Thanks!
I had them replaced last year and was not happy to see these as I had no idea they existed and looking at them I knew they would be a PIA...

 

What grease are you guys using? I have red sticky (forgot the name) in my gun that I used in my boat trailer bearings. Should I use that?

 

Anyone know if they're threaded in where they can be exchanged? Or, pressed in for the life of the u-joint?

 

Use whatever the spec on the new joint states. The OEM takes Moly-B.

‘B’ is for Butter.

 

Regular grease is what shops use on 18 wheelers, so if normal grease can do the job on these heavy duty trks just use what you want. That red grease, by the way, is heard to be sworn by as the go to grease, so I bought a tube. Lol, I have racing grease and all kinds laying around, but this thick sticky stuff should do very very good for the boat trailer bearings that get submerged in salt water.

If your concerned about what lube to use, don't. Just hit all the zerks every oil change or after every water submersion in between. You can never overdo greasing the bearings.

I've never seen a zerk or grease point on a universal joints bearing cap or caps. You can always get the grease gun on a universal joints zerk when rotating the shaft until it's exposes it's widest point where the fitting is at.

I had a double cardan shaft made locally for my Land Cruiser and I asked the shop what type of grease they recommend. He said anything Lithium based with moly is their preference.... so pretty much any moly grease you get will be fine. The FSM I believe states non moly. There are all sorts of discussions about Moly vs non, and generally anything with moly added exceeds the requirements for the non moly... In closing, I just stock moly grease for everything rather than different guns with different stuff. Been using the Red Line stuff... its expensive though.

 

The Moly also has an added benefit that if it ever dries out, it is still slippery like dry graphite. Its also highly impervious to water compared to other greases. Also, its a great electrical conductor.
