Inner CV boot kit came with two kinds if grease. What do?

Started slinging grease on my passenger inner CV boot from a tear. Found an inner boot kit from toyota that isn't the inner and outer kit. Just the inner. P/N 04438-04050.

Online parts diagram shows a boot, tripod snap ring, axle snap ring, small and large boot clamps and two bags of grease.

I've got everything apart with the new boot on and I go to get the grease and realize there's two different kinds included in my kit, a dark and a light. Everything I've found suggests the dark is for the outer boot but this kit isn't for an outer boot.

Grease part numbers are 10059029 60 grams of light colored and 10058992 125 grams of dark colored.

Do I have the wrong kit, right kit with wrong grease, or is it all good just use both?

Tan grease goes to the outer joint. Dark grease is for the inner.

 

it's a single CV boot kit. Why two kinds?

 

Go with the higher number. Maybe it's mo betta

 

It also doesn't seem like very much of the light stuff.

 

that’s just the way it is from Toyota. My best guess is the outer cv joint sees much more articulation and movement at the spindle so it would require a different viscosity formula.

see here for reference from @turbodb

My intuition would think the side with more articulation would get the higher quantity and lower viscosity. But idk anything about any of this.

 

Ya saw that when I first started this.
Looks like the dual boot kit gets two bags of each color. :frustrated noises:

 

At least on a 1st gen, the joints are completely different - we have one CV joint and one tulip. Different forces, ball vs pin bearings, and whatnot, so Toyota puts the "ideal" grease for each.

One thing that's interesting is that for a 1st gen reboot kit, we get 2 packs of each color grease (for a single CV reboot). I'm a little surprised to only see one of each color in the 3rd gen kit - though I must admit to never having taken apart/rebooted a 3rd gen CV axle...

 

According to the Toyota parts website this kit fits tacomas between 2005 and 2021

 

I’ve done a few second and third gens. Each time the customer brought me the kit and although different part numbers, the only differences I’ve seen are style of clamps (pinch vs fold over) and the way the grease is packaged (single large bag or two smaller bags). The boots are the same AFAIK or at least they fit the same.
I really should’ve noted the parts numbers for the different kits to see what Toyota says is the application for each.

 

They are the same grease. The larger pack is darker because there is more. They are just giving you the right quantity for the job by adding up two packs.

They are both type 000800331 “GKN driveline grease” as labelled. The package part number difference is not for difference greases, just for the different size packs.

Neither pack is is the type 10003270 black GKN grease that comes in some kits.

 

OK, those are all post-1st gen years, so I'm not sure exactly what you're getting at... Sorry if I'm being dense.

Yeah, I know the one bag vs. two thing - it's the same deal for a 3rd gen 4Runner/1st gen Taco. Still, with the 4Runner kit, there's 2x as much grease in the single bag. In the 1G Tacoma kit, the there are two (2) bags of light grease at 125g each (250g total for one boot).

If @Double Phister only got 125g of light grease in the kit, I think he got a kit that's missing grease. But again, having only done 1st gens (and 3rd gen T4R), I can't say for certain.

OK, I figured I should read the thread more carefully, rather than just start where I was @ mentioned.

I see more what the issue is now. @Double Phister bought a boot kit for half of his CV axle (part number 04438-04050). As such, we should expect that it only comes with two grease bags, since those two bags will fill a single boot. The question then becomes the one(s) he originally asked:

1. Did he get one pack of wrong grease? (i.e. should he have gotten two packs of dark grease?)
2. If one of the packs is wrong, does it matter?

My theory is that the answers are (1) Yes and (2) No. However, even though I think it probably doesn't matter, I'd personally want it to be right on my truck, so I'd probably not put both greases into the same boot before getting some confirmation from Toyota or something.

@Double Phister - Do you have a dealer nearby that you could go ask? I'd "ask" by seeing if they have another kit you could purchase, and see what it's got. If two different greases, you're probably fine. If two of the same, well, then you know you got a bum kit.

Besides asking Toyota, if you have an FSM, that's where the 1st gen greases are specified. Here's what it says for 2000 Tacoma Factory Service Manual \ Repair Manual \ Suspension and Axle \ Front Driveshaft > Reassembly




Also - my recommendation when rebooting a CV Axle would always be to reboot both sides at the same time. If the rubber/plastic on one side goes, the other side has probably been stressed just as much and is probably close enough to going that I'd want to get a new boot on there. Just my opinion of course; do as you see fit on your truck!

Good catch. I think you nailed it.


(I left everything else I said, mostly because I think it's generally a good approach to working through a problem like this, lol)

 

The key is the actual black (moly?) grease in some kits has a total different grease type number of 10003270, as opposed to the type 00803331 grease in both bags in OP’s kit.

 

Better get your GKN Drivelien Grease while you can. They are going on strike:

I feel better about this already. Good catch on the grease types. I was stressing because all of the local dealers parts departments are closed tomorrow and Monday for the holiday. I’ll compare the two more closely in the morning and get this buttoned back up.

I think the inner failed do to my lift causing the ribs to rub together. The fix for that is more weight in the front end. At least that’s how I’m going to justify a bumper and winch.

thanks for the responses guys.

 

GKN is the grease maker, so I’m pretty confident that their part number dictates the same grease in each bag.

It’s interesting to me that Toyota is using GKn as a supplier. They are pretty legit in the driveline world, making driveshafts and CV Joint for all sorts of automakers and motor sports, but mostly in Europe. Even their grease has all kinds of literature about it. Found some good stuff to nerd out on looking into your questions.

Good luck with the install.

I found the answer to my own question! I’m assuming you use both on that cv boot.
I was scratching my head because it ordered both inner and outer boots as a kit and it came with 4 packets of grease and I was trying to figure out which one goes with which

 

Yeah. You have two packs of the GKN type 0080331 Grease and two packs of the GKN type 10003270 grease.

 

The mystery continues. After squeezing out the grease from both bags into the boot I can tell you they are definitely different colors and not just an illusion due to quantity. I put the darker one in the boot and the lighter all over the tripod. Oh well. It's all back together. If it goes sideways I'll replace the axle.
