Outer CV bands let go

When I redid my torn outer CV's, I think I clamped on the smaller portion of the outers a little too far away from where they should sit. A few days later the large bands of the outers let go and started flinging crap everywhere. the cups of the actual joint would also spin on one side of the boots depending which way I was turning. This didn't last long as soon as I noticed it, but it made for a very pissed off me and led to some emergency temporary repairs. The boots still looked to be in use able shape, but since I have patched the issue on both sides. I have had a never ending problem with grease being flung out. Being that the outer boots are not rubber and are some sort of nitrile plastic material instead, is it possible that the boots are just damaged and I need to replace them YET AGAIN?

I attempted to get new bands alone from the dealer but apparently the only way to get those is with a CV boot rebuild kit. How stupid. So for now I am using smooth style plumbers style hose clamps.

Is it also possible to pop off the out CV joint without pulling the entire axle off? The FSM states you have to install the outer boot by removing the inner joint and boot first, but I get the feeling you can pop off the outer alone.

 

Nevermind. I'm just going to replace the boots again with some long travel 930/934 high quality rubber ones from SDHQ. I'm done messing with crap ass stock CV boots. One last tear down, and I should be good for a long while.

I just wish I knew about these sooner when I tore them down the first time.

 

FYI - no way to replace the outer boot without removing the axle. The axle is pressed into the outer birfield joint.

Good call on the SDHQ replacement boots.

 

I attempted to check for some sort of retaining clip when I first replaced the boots and could never find anything. I think in order to remove it you would have to reverse press it out which would require removal anyways. Kinda sucks.

I hear they are made out of some thick high quality rubber. Which is great for longevity. Even more so because they are supposed to barely rub with higher angle lifts. I'll lube up the fins every so often with silicone paste. Definitely a step up from the suck stock material boots.

 

To be 100% fair about it, it isn't so much that the Factory CV Boots suck; They don't.

I have never had a CV Boot failure from wear. I have only replaced one since 1984 and it was caused by an impact from road debris.

What is the real issue is you have changed your drive angle on the CV joints and are stressing the boots beyond what they are designed for. Not Toyota's fault.

By your own admission:

 

You are not wrong. In terms of flexibility though, they are not very good. I would attribute that to the materials they are made of, which I was not fond of the moment I found out. Once you change the angles on these trucks by lifting, the length of time the stock boots will last before they either tear or the bands give up the ghost is a total crap shoot. As far as using them for stock purposes and usage only, they SHOULD last a long time.
