Great writeup

That method would certainly work and would eliminate the difficulty of pulling from the diff, trying not to mess up the seal, messing it up anyway, and having to get the new seal seated right. I believe [MENTION=491912]newton22[/MENTION] used this method in post #6 of this thread here: https://www.toyota-4runner.org/4th-gen-t4rs/287118-cv-axle-boot-repair-sanity-check.html#post3503394

I accidentally let my current CV go to long without grease and its not in the best condition anymore. It doesn't click but has some more play than the good condition CV, so that lead me to source another one to rebuild.

Haha thanks lol. I hope it doesn't, but when the time comes, I'll grab some pics! :thumb:

Yes I enjoy this method as long you don't mind the axle grease coming out. With this method you don't have to mess with the CV on the wheel hub side.

Great write up. Subscribed. Have a torn cv waiting for reboot

Thanks! Let me know if you have any questions about the reboot and post some pics!

Great writeup

Thank you!

Thanks for elaborating on this method! Definitely a big brain move to eliminate pulling and reinserting into the diff.

Thanks for the detailed write up! Just noticed my inner boot passenger side is spewing grease. Ordered the 5th gen boot kit from local dealer and will probably attack this next week / weekend.

[MENTION=554043]bbix333[/MENTION] did you replace your boots? Did the 5th gen boots fit the 4th gen axle? Planing to do the same thing but it would be nice to get confirmation that everything fits.

Not yet. I have the kit from the Toyota dealership. I temporarily installed cheap cardone axles off amazon ~$55 each. I probably won't get to it for a month or two. Just have too much going on.

I've seen it done now probably 10 times on Facebook in the group 4th gen 4runner Familia, so I think you should be okay to use the 5th gen boots.

I ordered the 5th gen kit, will hopefully tackle it this weekend and will report back. Really no reason why it should not work. [MENTION=429038]y=mx+b[/MENTION] thanks for the write-up and for mentioning the 5th gen kit.

Sweet! I'd love to have your feedback on the 5th gen kits, I link your update to the main post so everyone can find it.

Got this done over the weekend. Was not as bad as most make it out to be. Took me 3 hours for the first side, and 2 hours for the second, beginning to end including removing and installing the CV axle. About 1 hour for the reboot part. I think the most frustrating part was removing the dust cap! To get the CV out I used a large screw driver and a 4lb hammer. With the screw driver in on of the groves it took only a couple of hits with the hammer to get the CV out. Requires removing the skid plate, but well worth it.

The 5th gen boot kit (04427-60131) is a perfect fit. The inner boot is the same material as the outer boot and has more fins compared to the 4th gen boot. Hopefully it will be more durable. The grease capacity is a bit larger, that's why there is an additional small tube of grease. Given that both kits are the same cost this seems like a nice free upgrade. I did get the worm drive clamps from Amazon (or eBay) since they are easier to install and allow for adjusting the inner boot on the truck (boot stretch). Snap ring pliers are definitely a good recommendation, make removing and installing the snap ring really easy.

Will definitely use these next time I have an axle to do. My spare isn't necessarily torn just seeping. I'll try a worm clamp first. Nice pics.

Dude, those look fantastic! I really appreciate the pics too, those are a great addition. I've already linked it on the first page and made the recommendation to go the 5th gen kit!

Yes, I like them. Thanks for your write-up, that helped a ton.

I was wondering, since the 5th gen boot has more fins wouldn't that make them rub against each other more that the 4th gen? I have a torn boot because of the rub. I already ordered the 5th gen boots though lol.
I just wanted to know how yours are holding up.

Great write up, thank you!

How tight did you tighten the clamps? I know it's hard to say exactly but I used a 1/4" drive ratchet/socket but didn't want to go too tight. Got a little leakage and used a screwdriver until I couldn't turn anymore. No leakage since. I also wrapped electrical tape around the clamp seat on the boot to protect the boot.

Does that seem good or should I tighten more with the socket?

Thanks dude, glad it was helpful!!

I did mine with a screwdriver first and noticed it was leaking a tad bit after probably 300 miles of driving


I then followed up with my mini impact like this one below and cranked on it pretty good. I think it can only do like 65ft-lbs max on a fresh battery in ideal conditions, so it probably wasn't close to that. Its really intended for woodworking stuff but good for small automotive tasks. I'd say if after a few miles of test driving you don't notice any extra leaking out, then its good to go! Good call on the electrical tape, extra protection can't hurt!

Hopefully [MENTION=145671]BagiMT[/MENTION] will chime it, but I think the main benefit is the 5th gen inner boot is the plastic material like the outer. So when/if it does rub on itself, it doesn't chew through the more robust material. Also I think the more pointed shape of the 5th gen boot fins helps them to compress better than the thick and rounded off ribs on the 4th gen. This is just speculation though, since I haven't run the 5th gen kit myself. I have a spare CV I want to reboot with the 5th gen kit, so definitely let us know how it goes!

Yes, the 5th gen inner boot is more like the outer boot. Same material, thinner finn's than the 4th gen boot. I stretched mine a bit and have not noticed any rubbing (3" lift). Might be interesting to look in the 5th gen section to see if people still have torn boots. I just assumed Toyota changed the design for a reason and went with it. Time will tell how it holds up, so far so good.

Thanks thats good to know. Il be doing mine soon. Its has a small tear for a while now, hopefully i haven't ruined the actual joint.

 

[phatcheeks]

So I finally did it. Just on the passenger side. Now I want to do the driver side to be even lol. But its fine for now. The whole process took me some time since I was taking breaks and going slow. Im sure the next time will be much faster.
I had to do the knuckle seal too because for some reason it was torn and the little circle spring came out with the axle.

5th gen boots.
