Boot slide mod (my experience)

Yes. Personal experience,
Whatever your road speed is, the CV joint is spinning considerably faster. .25 oz is enough to explode a CV axle.

 

Is there a better alternative besides the expensive OEM ones? I read somewhere about Moog ones but cant seem to find them

 

Dorman makes them also. You will need to find the proper size.
Also, the proper tool to compress the clamps.

 

Thats interesting, OP reported back with 15K and no issues.

I read a post years back with the same mod, the user installed two clamps on each side, one opposite the other to counter possible weight rotation issues.

I have the tool for the OEM clamps, no clamps though.

 

A little more feedback on this...

I never had an issue after this mod, boot never moved. West Texas speed limit is 80 mph, no vibes at all...

 

So you have used a hose clamp and that was the only thing changed and then you had enough vibration to "explode" you "CV axle", as you put it?

The factory clamps are biased with extra material to one side, too. The mass difference between a 1/4" hose clamp of the axle diameter and the factory clamp can't be more than a couple grams.

The CV joint is spinning at the same RPM as your wheel/tire. It's rotational velocity is considerably slower. I calculated the angular velocity of an object at a radius of 1" (which is larger than the axle). At 75mph vehicle speed on a 31" tire, the clamp on the small end of the CV boot is rotating at about 5mph (86 rad/sec). At the actual boot clamp radius the G forces are around 10-12G at 75 mph.

 

I get that $10(ish) is not cheap but is that a deal killer? Why not just buy a kit that comes with the tool to crimp them? They only run $30-50 and it's really easy to use.

 

Just lifted the truck a couple hundred miles ago and noticed some rubbing on both sides. Ordered the clamps and hope I can get them on and installed soon. It’s my daily driver so I’ll have to drive it to work. I have about a 40 mile a day drive. Fingers crossed

 

These clamps are really good quality that I have used for the taco.

Never had a single issue on my 2019 with this mod. My current 2021 with 16k miles has the same mod since 1K miles, boots are fine and have not moved. Mine are slid over 3/16”, the width of the band, would not advise going any further. The fins are just far enough apart that they don’t touch, a credit card would just about bridge the gap.

 

That's the same price that you can find the knipex fixing pliers.

 

Yessir, mine haven’t moved yet. Though I haven’t done much off-roading at all

 

somehow came across FSAE page saying make sure axles are clocked

Does this matter?
Probably didn't do it when I rebooted. Never once seen mention of it in a repair manual ever.
Far as I'm aware, no issues. Same for anyone else.

without tracking it on purpose during a reboot, I doubt it luck lands it on like this.

seen maybe a whole 3 people on the entire internet say to do it
if it was a thing, I imagine it'd be known.

 

does anybody know what size oetiker clamp to use for this

 

It's probably applicable if you had independent rear suspension with rear CV axles.

The front CV axle has a birfield type outboard joint to accommodate steering angles, while the inboard joint is the tripod type. The "phasing" is therefore moot.

 

Is this what you’re looking for ?

My FI motorcycles use oetiker clamps on their Fuel system, it's common for people to replace them with worm clamps because that's what they know, they work but often tend to chew up softer and thinner rubber they they are clamping. Where it matters and the rubber is thin you will rarely see a worm clamp installed by a manufacturer.

Not trying to insult anyone's method but a real mechanic would frown on using a worm clamp on an axle shaft. Personally there's no way I'd use a worm clamp there unless it was an emergency repair. Nothin says shade tree like the wrong clamps. Worm style are more common on radiator plumbing but not on axle assys. There's a reason these style (oetiker) clamps are widely used in these type applications across almost all manufacturers, it's impossible to overtorque them and they are far gentler to the item they are clamping.

 

10’s of thousands of miles on several Tacoma’s, zero movement or vibrations with the worms. Like anything else, use quality parts & install properly, always monitor your systems.

PS, I seen and dealt with many so called expert mechanic's over the years, I’ve learned to repair most of my junk because of their work practices.
