Lubricating drive shaft or propeller on 2006 4x4 Tacoma's...

Do not use moly for the U joints. That stuff will squeeze out in 5 mins. I believe there is 5 fittings.

 

Dang I only saw 3 on my drive shaft. But I could be wrong too. What year Tacoma do you have?

 

There should be 2 on the front drive shaft. I have an 05 DC

 

Oh okay so where are they all located?

 

The ones on the front DS are a bit of a PITA. One is on the U joint right at the transfer case, most difficult to get. The other is on the front U joint. These ones are on the inside of the U joint, if you stick your finger between the driveshaft and the U joint, it will be in there. Hard to explain. Its snowing out or I would take a pic for you.

 

So there's 2 on the front DS? What about the other 3?

 

The other 3 are the ones you posted pictures of earlier. The difference between the GL1 and GL2 is that GL2 isn't as thick when its cold so you can actually pump it out of your grease gun when its 10 degrees. You can also use it summer with out any problems.

 

Oh okay so GL2 is okay for all year round then? Also, those pictures I posted earlier, the very top one was the front of the DS so is that 1 of the 2 that he was talking about? Or is there 2 more that I didnt get with the pictures? Oh and here's the grease I bought. Is this one okay? I know synthetic wasn't necessary but just got it any ways.

The rear drive shaft has 3 u-joints with a zerk on one end cap of each (the ones you posted pictures of). The front drive shaft only has two u-joints and the zerk is on the body of the u-joint. You might have to spin the front shaft so zerks are on bottom to see them.

 

The one right on the transfer case is a bitch to find, even more so to get grease into.

 

See when I took those pictures, I could have sworn those were the only 3 zerk fittings there were. Can anyone get some pics for me of where all 5 are?

 

Ah crap. I just noticed this post and I ordered grease with moly in it! Is it really that bad for the U-joints?

 

Thats what she said

 

So anyone else doing the spline mentioned above?

 

So how come we shouldn't use moly on U-joints?

 

you can try it but I doubt it will last long in there, moly is a fairly light grease.

 

Moly based grease is more for high shock load, low speed type applications. Something like a heavy pivot point on a machine with bushings, pins, and the like. Your u-joints are constantly moving, but the shock load is not there.
We use a grease made for John Deere on most everything (Ag equipment) except where a moly based grease is specified. SD polyurea grease, Deere part No. TY6341. I just bought 3 cartons of it last week. $4.20 per 14 oz. tube. One tube would last you a very long time I would think, if all you are doing is greasing a few U-Joints.
We use it on our u-joints for our industrial power units. We have a bunch of U-joints running this stuff with no problems. If you have a John Deere dealer nearby you might check there. We grease our U-Joints until grease comes out of all four cups. You might want to clean up the mess though when you are done. Otherwise, you will have grease all over everything when the drive shaft spins it out.

 

Oh okay. Well maybe I will just order some different grease that isn't moly.

 

You should be able to find a good grease anywhere you can get motor oil.

 

Okay, greased up my U-joints a little while ago! Still only 3 zerks total. 1 on the back, 1 in the middle and 1 in the front of the drive shaft. All 3 zerks got grease to all the U-joints. I did what was told. Squeezed out the old nasty black grease until I saw the new grease peak through then I stopped and wiped up. Did I miss something? Never mind...I did miss the 2 in the very front of the DS! Gosh dang it! Oh well, I'll get those tommorow.
