how do i lube a 2wd slip yoke?

[2rz-fte]

Plenty of tutorials on the 4wd trucks but not much info on the 2wd. Do I just slide the drive shaft out, clean, lube? Does the driveshaft hold in the tranny fluid? How do I realign the driveshaft support? Thanks for the info.

You don't need to pull the shaft to lube the slip joint. There should be a Zirk fitting located on the the rear most half of the shaft. A little squirt of grease should be all you need.

The 2WD driveshafts do not have zerk fittings....

So Zirk's were standard issue w/ 4Wheel Drive and non existent on 2Wheel models. Who's bright idea was that? LOL.(Stupid Bean counters @ Toyota- I'm guessing) I'm glad that I've got a 4x4 model, cuz there's no way I'm going to drop the drive shaft just to grease it!

4WDs last twice as long and need twice the maintenance

?? Procedure for lubing a 2wd??

If this is for a Tundra,and not a Tacoma, then yes, it looks like you can possibly lose tranny fluid once you pull the slip yoke. There is an SST listed in the FSM that you insert into the back of the tranny to prevent fluid loss. As to whether that is just for drippage, and to keep debris out of the tranny, or to stop a full blown waterfall of tranny fluid, I dont know....
And yeah, that seems like a dumb design, considering the 4WDs have a bolt-on flange, so no need to pull the yoke out of the tranny.

I'd suggest seeing if you can replace the Ujoint with a 4WD one that has a zerk, (wont help this time, but would make future lubing easier), but then I dont know if the added weight of the zerk would throw off the balance of the shaft... ??

Maybe you could park the truck on slight downhill incline, so the tranny tail is higher than the front....May keep fluid from pouring out...???

there isn't one because there is nothing to lube on the front suspension, the drive line, or the rear suspension of your 2wd tundra.

This is exactly what I was afraid of. Because I read that the tranny fluid is supposed to lube the splines. Terrible design because the tranny and the slip yoke require very different type of lubrication. Anyhow my tundra's clunk is very strong and I really need to address it.

Now it leads me to this question.... If I put the ford PTFE lube on the splines, won't that grease get into the tranny? That seems like a terrible thing. I'm not sure if I want grease and tranny fluid to mix.

[Stone_Blue]

So if the tranny fluid lubes the yoke splines, why would you need to lube it? If your driveline is already clunking, then you probably already need to replace the U-joint(s), since lubing them after you already have a clunking is pointless. I coud be wrong, but it looks like the center bearing does have a zerk fitting. You could maybe try lubing that...

I'll definitely climb under there and shoot some grease into any zerk I find. The thing is I don't feel the super this tranny fluid is sufficient for the high pressure sliding motion. Its more of a extremely viscous with Teflon it moly type of application.

[Puffnstuff]

The dc has a two piece shaft and magically enough no zerk to lube the spline with.

^ now that's funny

[tundrunk]

LMAO!

The driveshaft doesn't hold any fluid in the tranny. I'm not sure where you read that Stone, but it's not true, there's a seal on the tail of the tranny which is much like the crankshaft seal. I've pulled my driveshaft off twice, don't worry about fluid but make marks with a paint marker and remember the orientation of shaft to shaft and shaft to rear end for reassembly. Might want to take pictures to make it easier to remember where things lined up.

There isn't a way to lube our joints as far as I know, at least not a way that will last long. You may be able to grease them if you take the joints apart but that won't last a long time since you can only apply the grease externally. Might have to look to replacements if they are acting up, if they aren't then don't mess with them.

[Stone_Blue]

I said I didnt know if pulling the yoke would gush fluid, or if it would just drip some.

"As to whether that is just for drippage, and to keep debris out of the tranny, or to stop a full blown waterfall of tranny fluid, I dont know....""

I've never had the misfortune to ever own any 2WD, rear wheel drive vehicle.

Straight out of the FSM:
