07 V8 4x4 Zerk Fitting Pics

"I have a question..what is the best way to rotate the drive shaft so that the zerks are pointing the right direction?"

I just move the vehicle.

You're looking for a lithium-based grease, grade NLGI-2. I've seen the moly as well, but since a lot of people here swear by Mobil 1, I went with that instead. I saw some really cheap no-name lithium grease at the auto parts store that said it was "compatible with NLGI-2", but didn't say it actually met the specs.

Here's the data sheet on Mobil 1 grease:

I didn't find Mobil 1 at the auto parts store, but I got it at Farm & Fleet. I also think I saw it at Sears. Shop around a little bit and you should find it.

thanks toto, i just sucked it up and did the mobil1 for all too.

buckfever, if you have the v6 4x4, in 2h you can freely move the front driveshaft. the rear you'll have to move the truck forwards/backwards a bit to position. any more questions and i'll be happy to answer....

there's a good write-up on toyota120.com ... click maintenance --> then click driveline service... don't know if i'm allowed to reference another site... forgive if i can't... i'll take it right off.

Use the jack to lift one of the tires off of the ground -- this will allow the driveshaft to turn freely.

I just started to have that drive line clunk (again) for a couple of days now and have been too busy / too lazy to go out in the garage and pump some grease.

About a year ago I bought a grease gun, flex hose and some mobile 1 synthetic (pink) grease from pep boys... put it it all together and have been eliminating the clunk for about a year.

Both quotes are from previous post by Buckfever.

"I tried to observe for that expansion, when I was greasing up the front slide yoke zerk, I couldn't see anything after pumping a good amount in so I stopped. I don't have a good rule of thumb on that. "

(you can see the drive saft expand, but it is difficult to observe)

"For the U joint, you can actually hear when it finally starts to express, although you can visually confrim it, 6-7 pumps is all it took. I'm putting in around 16-17 pumps on the Slide Yoke fittings. I've read that you don't want to put too much, but then the guys that are successful at eliminating the clunck via greasing the driveshaft, have reported being aggressive."

(It took me more than 20 pumps on the front and back slide yoke to make the shafts expand. The shafts only expanded about the size of this dash ( - ). I hope that is not too much!)

Thanks for the great pics Buckfever!

Cheers

What is the size of the zerk fittings? or is it one size fits all?

Per the recommendation of others here this is the one I picked up at Autozone, the flexible hose needed to be purchased separately:

I use both hands to push it on the zerk, once it's on I can hold it in place with one hand and then I find the pistol grip. The pistol grip and the flexible hose, I think are both essential in DIY. I also find that I need to move the truck to put the zerk fittings in the most accessible positions, again per the recommendation of someone else here.

For the U joint, you can actually hear when it finally starts to express, although you can visually confrim it, 6-7 pumps is all it took. I'm putting in around 16-17 pumps on the Slide Yoke fittings. I've read that you don't want to put too much, but then the guys that are successful at eliminating the clunck via greasing the driveshaft, have reported being aggressive.

Zerk fitting size

There is one standard size that you will see the vast majority of the time. Unless you are deliberately looking for something different you are unlikely to buy the wrong thing.

I second the suggestion of getting a pistol grip gun and a flex hose. that will make things much easier.

 

[Jacobzky]

thanks to this thread and nice detailed pics BFever

went to napa auto parts and got the pistol grip grease gun and it comes with the flexible hose, tried the tip and it fits. the flexible hose is nice to have .

 

[Buckfever]

One word of caution, when you're doing the rear axle, there is a heat shield has a sharp edge. Be careful pulling off the fitting as I cut myself pretty good.

 

[Jacobzky]

too late, i slightly cut my knuckles. thats is why, it is better to position the zerk downwards, its safer to pull the hose.

are all M1 grease the same? color coded?


Why am i having a hard time, taking out the hose fittings off the zerk? am i doing something out of the norm?

 

[Buckfever]

I've only seen the one and in terms of specifications from what I've read, the separate grease types has been dropped from the more recent manuals.

 

[Jacobzky]

this one?

 

[Buckfever]

Yeah that's it.

 

[Jacobzky]

Thanks to this thread, i was able to do DIY it, though it takes me longer than changing oil but its a good learning experience.

I dont know how much is left on my grease gun, can i just leave the grease gun as it is or do i have to take the tube out?

 

[Buckfever]

I left it as is and it worked just fine the second time. I don't think all that much grease is used each time. Should last a while.

Buckfever, just wanted to say thanks for this thread! I was able to do this last night with ease, thanks to your instructions! And I've only had this truck since Monday night!

Thanks to this site, I was also able to flush and replace the differential oils and transfer case oil. All Mobile 1, as described in this thread.

Thanks guys & gals! :

Does anyone know what the pressure limit is on the seals in the driveshaft? When I lubed mine I only put 2 shots each for fear of blowing out the seals. It only worked for a few days before the 'clunk' started again. I know it needs more grease but I don't want to overload it.

I just went to my local tire shop this morning for a rotation and asked them to hit the grease fittings. When I picked it up, they said there weren't any and aren't on a lot of newer cars, but they lubed the u-joints and other areas of the drive shaft.

As I pulled out of the parking lot, I called my local Toyota service guy and he said "I don't think there are zerks on the 03s"

Can anyone confirm or deny this? Perhaps I just have bad service advisors in Ohio. Thanks!
