Tackled this today, the lock ring pliers in the first post made easy work of ring. 5th gen boot kit and eBay clamp set. Simple job, have plenty of rags and don’t be scared to use them.

Looking good! Thanks for sharing the pics!

Thanks for the excellent writeup. Where did you find "rolled edge" worm style clamps? Seems like all the ones at the hardware store are square edged and have some tabs under the worm gear that look like they could cut the boot....

Thanks again for the writeup. Have you found the outer boot has held up without performing the boot slide mode on the outer boot? I have not seen anyone mention sliding the outer boots, but it seems there is some slight rub of the baffles, although definitely not as tightly pressed together as the inner boot. Thanks again.

Probably have to Google them and order online.

The rolled edge worm clamps, as well as all the other parts, are linked on the first page. I used these specific ones: Set of 8-Toyota 4Runner CV Axle Repair Clamps Kit, Leaking Boots after Lift Kit | eBay

The outer boots are a more plasticy material vs the inner boots more rubbery type material. The plastic outer holds up much better to the baffle parts rubbing than the rubber inner, so stretching wasn't really necessary.

I've put about 40k miles on these axles since rebuilding and replacing, and they've been holding up great!

Thanks much for the replies.

Think those 9mm wide clamps from ebay will just barely fit the boot channel on the 1st gen Tundra but it seems 9mm is a little wide, although the rolled edges might help. OEM clamps are 7mm I think. Can put a couple ¼” wide ⅝” $.99 hose clamps from the hardware store together that seem like would make a nice “balanced” ¼” wide replacement (opposing worm assemblies). But they don’t have rolled edges.

Like you without trustworthy Toyota axles to rebuild, was able to find remanufactured axles from Toyota @ about $77 each (with core trade-in of old ones). For reference: this was part #434300c01084 for 2003 Tundra AC 4x4 (can add '84' to the end of Toyota part #s to see if there is a remanufactured version for other vehicles).

So could retain factory axles at just a little more than the cost of the reboot kit but with boots already installed. The inner/outer boots on these axles seem to be the same material, not plasticy like the 4th/5th gen 4Runner. The inners definitely need stretched. The outers also seem a pinched though like in this photo of someone else’s truck (especially at turn lock) so look like th outers need the BSM too.

If the BSM mod doesn’t stay just relying on the clamp to hold it in place, then will need to do the internal circlip mod next.

Sounds like you never had to do the internal channel spacer?

How has the wire tying held up? Got a pick of the final product?

Thanks again.

I really appreciate this in-depth write ups for noobs like me.

Anyone have issues with the 5th gen boots leaking? I've done 4 separate 4th gen axles (two 4th gens in the family) in the past 3 months and 3 of them are leaking. The 4th only has ~700 miles on it and the other 3 probably have 2000-5000 miles on them.

They're all leaking at the large clamp on the inner boot just ever so slightly. I used the Toyota clamps instead of the worm drive ones, but I bought the special Toyota tool and got the clamps really tight and within Toyota spec.

I have some of the rolled edge worm drive clamps I can replace the Toyota ones with, but figured I'd ask before I go and cut off the other clamps and replace them.

I did not stretch any of the boots either since both 4Runners are stock height.

I have a 5th Gen (2022) 4Runner TRD PRO, lifted and on 33's.
I was leaving for Baja Monday morning January 29th, and since the weather was cold that week, I waited until Saturday Jan 27th to rotate the tires.
Just as I was about to finish, on front driver's side, when I pulled the tire I saw the torn inner boot.
I was able to find a CV Axle and replace it on time to be able and leave Monday, but, in the process, I damaged the yoke seal, which I couldn't find anywhere, couldn't even get the part nber fir it anywhere so I went with it as is.
At my return from the trip, I had to leave for Europe within a week for another 3 weeks, and ordered the CV Axle kit($210CAD) as well as the yoke seal, which was a special order.
They just arrived earlier this week, and I've completed replacing the inner boot.

Question for you people, have you experienced any issues with leaks after stretching the boot, I'm debating doing it, right now, and crimping the OEM crimp, as I hate the idea of a hose clamp, since they can both snag on things as well as come lose..

Lmk please.
Thank you kindly.
