4Runner / Taco CV Boots

[ajonesnv]

Can any one definitively answer this.

Will 1st Gen Tacoma CV boots fit on a 3rd Gen 4Runner CV?

They are the same as long as it's an auto disconnect. Manual hubs are different.

Also are you lifted?

Yes I am.

I was told the Taco CV's are the same diameter the whole length where the 4Runner tapers.

If lifted go with the all pro extended CV boots. It's what I am running and so far so good. No rip. All you need to do is cut the stock CV boot of, but only keept the part that goes over the CV, it has special grooves. Then you slide the all pro CV boot over and clamp the shit out of it. I also added grease inbetween the rubber groves where they touch while the wheel spins. So this way the rubber doesn't rub through from rubbing each other.

Rubber CV Boots - Kartek Off-Road

call them and let them know what you drive. the best cv boots on the market i use these on all my toyota trucks

For future reference... in the taco world, for OEM CV shafts, there were two types, we called them:

The green label shafts (ADD hubs):

and the blue label shafts (Manual hubs).

(Best pic I could find, bottom shaft)


On the the two 4runners I've owned (96 and 00), and the others I've worked on, they all came with CV shafts that had no labels on them. What I did notice about the ADD Tacoma shafts vs the ADD 4Runner shafts, is that the Tacoma shaft was straight all the way across (see top pic for reference), and the 4Runner shaft was necked down in the middle. See above shaft in the below pic for reference....

I have no idea if one is stronger than the other, what I do know is that they are interchangeable between platforms, I currently run green label Taco shafts in my 4Runner.

I also know that the rebuild kits from Toyota are completely different part numbers....
*4runner is 04438-35060 price is $43.80 from Camelback Toyota
*Tacoma is 04438-04021 price is $35.02 from Camelback Toyota

My guess is the boot kits are not interchangeable, but I've never actually tried it so I can't be 100%.

Hopefully some of this helps.

Very helpful. I will keep it in mind. I was going to mention the sdhq boots for the tacomas as they have the grooves for the inner cv boot. Just replaced mine and when from touching to not touching. Just make sure you throw the right grease in the right side and you're gtg. Moly for the outer and a bearing grease for the inner.

THIRD EDIT - Not a good option. They will work in a pinch but the inner boot will wear out VERY quickly.


SECOND EDIT - They will work!! See post below the post below


Ok here are some pics from Amazon showing the boot kits.

4Runner 04438-35060:

and Tacoma 04438-04021:

As you can see, the grease is packaged a little fancier in the 4Runner kit, and the Taco kit uses the squeeze band clamps for all 4 positions, where as the 4Runner kit uses 2 fold over clamps for the inner position. The Taco kit also includes an extra snap ring, but for what I do not know. Maybe what holds on the articulating joint that you could possibly smack off like in this video?

There is a price difference on Camelback, the 4Runner kit is $43.80 and the Tacoma kit is $35.02. The boots look the same though. Another problem with the 4Runner kit is as of 11/19/2015 it's still out of stock.

So I ordered a Tacoma boot kit and went to reboot a 4Runner CV. What I found was that the 4Runner CV is bigger around than the Tacoma. I estimate the tapered down area on the 4runner shafts are actually the same diameter as the Taco shaft, so really the 4runner shafts bulk up.

On the outer joint, the boot will stretch enough to get on there and the outer band clamp fits just fine. The smaller part does take some working and forcing to get on there but it will eventually go. The smaller band clamp is too small the way it come but I was able to move where it's held together after punching out the loosest tab and flattening the second tab so the clamp bit where it needed to and wasn't raised up by the second tab.

On the inner joint, the smaller part of the boot will fit but again, the band clamp will have to be modified. The larger end of the boot will be extremely difficult to fit over and get in place. The larger band clamp is too small and I couldn't figure out a way to modify it. Also the band clamp will have to be extremely tight to have any chance of sealing the rubber around the 3 indents. I tried using 3 hose clamps daisy chained together, as I didn't have a large enough one, but I couldn't get them tight enough. They were cheap Harbor Freight clamps so I wonder if using a better quality clamp would seal it tight enough.

The snap ring is very different. The 4runner ring is larger:

and thinner:

So in a pinch, the boot kit can work for the outer joint, but the fight for the inner joint is just not worth it. And you would need to reuse the snap rings instead of the ones with the kit.

**EDIT** Using a 4-1/2" hose clamp you can seal the boot around the larger inner joint. See post below

Here is a write up documenting the differences between the two kits.

Save your self a headache and get all pro CV extended boots.

I'm imterested in going with the AP kit. Can you get just the grease from Toyota?

 

[Dephcon]

Sounds like if you buy the kit it comes with grease.

I don't believe so. I looked up the part numbers listed on the grease pouches but came up with nothing. The Tacoma boot kit grease packets for the inner joint have a sticker on the back for this company Greases & Grease Products and each inner grease packet shows 125 grams. So you would need 250 grams of inner CV grease. As far as the outer axle, I have no clue, but probably about the same amount. Also the Tacoma inner axle grease was darker and slightly runnier compared to the 4Runner inner axle grease.

Just go to autozone and get CV grease or just grease. And call it a day. You will only need to reuse your original CV boot. But only part of it. The part thay the big claml goes over. Cut that out nicley, put the AP cvboot, add grease, put a claml and call it a day. I did this and my CV are in great shape with 3" of lift after 3 months. Also you can add little bit of grease on the outer part of the cv, during flex or bumps the rubber rubz againts each other. So in theory ruber againts rubber creates heat/friction and can wear the boot out. So add grease in between to makw thay contact point lubricated and free of friction. Hard to explain but pictire it.

Further update, they do not last. After putting one on and running it for a brief time, the inner boot wore out and split. It being stretched so tight over the tulip made it wear out very quickly. So yes it will work in a pinch but it is a poor long term solution.
