    I had one factory shaft blow a boot after about 8-9 years and swapped it with a Napa. Still running that Napa shaft after ~10 years now. My other OEM shaft lasted about 16 years. I replaced it last year with another Napa. For the price the Napa shafts are hard to beat.

    @turbodb Hey dan, Zane (@Speedytech7 ) sent me to your write up for a reboot on a 4wd axle. I was very well documented as there is not one. I assumed the axles would be the same from 1st to 2nd gen and they basically are. The only thing i would like to point out incase another second gen person is in here looking at doing the reboot is that once you have the differential side tulip off and you are removing the 3 bearing head there is only one clamp ring which is does not require the snap ring tool you used on yours. Also once thats remove you then have to use some sort of punch/chisel/large screw driver and 4lb hammer and pound off the 3 bearing head, i couldnt find that detail anywhere and sat looking for awhile thats why im sharing it. Then you reboot and pound it back on, i used a 32mm socket which reseated it then put the snap ring back on.

    I used a pick to remove the top clamp ring. Then i used a flat air chisel hammer bit and 4lb sledge to pound off the 3 bearing head, pounding on the collar and not the 3 knobs where the bearings mount.

    Hope this helps anyone else.

    Dan your write up is killer for 1st gens and ALMOST was perfect for second gens if they had not changed it a tiny little bit.

    Now you have all the info incase you need to upgrade to a 2nd gen!

    Fucking god dammit, Dan, I read this whole thing, then nonchalantly popped the tripod off my axle and dropped it on the floor, without indexing anything to anything else. I don't even know which way was up!

    Popped 5 boots this year -- getting sick of paying for reman axles. So... here's to the sixth, when this one inevitably explodes because I installed the bearings twelve degrees off and upside down. At least I didn't pay $300 this time.

    Pretty sure it fit like this, right?

    This is entirely your fault.

    What clamps is everyone using now?
    The linked clamps see to be no longer available.

    Question on these clamps.
    If you do the boot slide mod with current boots and just cutting off clamp and sliding boot 3/8 inch will these clamps hold or will the worm type be better.

    I can see rebooting and keeping a peice of old boot clamped in grove with boot clamped again after that it wouldn’t take much because the old clamp in the groove.
    I may reboot in the future if needed.

    These clamps work just fine with the boot slide mod.

    Note, however: I am not a fan of the boot slide mod, as it puts additional strain on the boots by stretching them beyond their intended position. People like this mod because it makes it so the fins don't rub, but in my opinion, it puts even more strain on the rubber. The right way to make your CV boots last longer is to run a lift that results in reasonable CV angles. Anything in the 2.75" or under and you're fine. More than that and your CV boots are the least of your problems anyway, since the extremely high resting height will mean very little downtravel, poor ride quality, and a higher likelihood of significant strain - to the point of cracking - on the shock tower.

    Mine is 2.25 with 6112s and ribs are touching some.

    Post up a pic of your CV angle. Generally, I'd ask:

    1. Are you sure you're at a 2.25 inch lift? (and how did you verify this number)
    2. Are you having issues with eating through boots? (having them touch isn't necessarily bad)

    I’m probably just overthinking it,being proactive.
    The driver isn’t touching but the passenger is touching just a little bit .

    I'd run that as is. Angles don't look too bad (though I wouldn't add more lift...not that you were going to.) You'll put more stress on those boots by stretching them IMO.

    Nice writeup and photos.

    If just reinstall the same boots when a lift is causing the boots to split it will likely happen again. Allpro and others sell replacement boots apparently made with Neoprene. I understand CVJ Axles makes a silicone version also sold through Off Road Solutions, but for a lot more money (apparently pros and cons of silicone are: pliable / weather resistant from cracking over time but possibly less puncture resistant). These companies all have been very helpful over the phone verify the part number(s) needed.

    For example, here's the Allpro inner boot kit with grease and circlips...

    https://www.summitracing.com/parts/aof-ap-305847

    The full set of 4 boots...

    https://www.summitracing.com/parts/aof-ap-305849

    ...and here it is with special pliers for more $.

    https://www.summitracing.com/parts/aof-ap-305850

    And the CVJ boot with tulip adapter.

    https://www.cvjreman.com/product/boot-rt04/

    Longer boots can be installed in BSM position. Then stainkess steel, rolled edge, smooth interior, worm style clamps can be used (not sharp edge cheese grater style like from the hardware store). Cap Hardware sells Norma Toro or Carlyn very reasonably.

    https://www.caphardwaresupply.com/p...yle-hose-clamps-9mm-wide-25-40mm-w4-stainless

    https://www.caphardwaresupply.com/product_detail/40-60mm-torro-thin-clamp-partial-ss

    Think it was $15-20 including shipping for a set of eight. Don't then have to buy special pliers and also can tighten as desired with more control than the other style to address grease sling.

    Details on this for Tundra is here and can extrapolate for Taco:

    This is not entirely true.

    Over time, CV boots - like all rubber components - develop a memory across their usual range of motion. Often times, CV boots split within a month or two of installing a lift. This is because the boots are now "outside of their memory" and crack due to the unusual/new stress.

    Installing new OEM boots allows the boots to develop their memory at the new ride height, thus lessening the likelihood of cracking. This is why a lot of folks can reboot their axles with OEM boots after installing a lift, and then never have an issue with the new boots cracking.

    The Porsche 930 boots can be used, but in my experience (I've never run them, but I've had buddies who used to run them) they tend to use thinner rubber than Toyota boots and thus rip more frequently in off-road conditions.

    One thing to be aware of with clamps is that the worm-style can loosen on the trail, or the worm-screw can get caught (more easily) on debris.

    Additionally, it's already difficult to remove the lower shock bolt with the traditional CV-boot clamps; it could be even more difficult with a worm-style clamp installed.

    The OE style clamps are $15 for a set of 24, and the tool to crimp them is between $23 and $32 depending on the features you choose, so I'd probably go with the OE style, even based on cost. You get to keep the tool for the "next time" or to "help a buddy," which is always great!

    Good point on the clamps and tool but sometimes they leak. And new boots if rubbing due to high angle can wear down a ring at the contact point of each baffle, and that causes them to split because really they're are being disintegrated. It's not from hard rubber repostioning that can cause faster splits with old boots. Look at the BSM thread for photos of this. Have experienced it. Have a new set of OE axles at high angle that are doing this and purposely decided to wait to reboot them until when they are near worn out to get a bit of use out of the already installed boot.

    Here's a writeup with photos of installing the longer boots for Taco.

    If your CV angles are such that you're constantly rubbing fins, then the correct solution is a lower lift. :wink:

    The Porsche Boots - that I've seen - have more fins and thinner material, which make any rubbing, worse. The BSM is suggested by some, but others say that puts the boot under constant strain by stretching it past the Toyota design. In both cases, I'm always a proponent of a lower lift to reduce the strain on the boots, since a lower lift has a lot of other benefits as well - more downtravel of the front suspension being the most important, making for both a better ride and more capable wheeling truck.
