Question : CV Boot replacement for just the outboard joint (LX470) (1 Viewer)

[suzie]

There's a good write up on CV boot replacement for both inboard & outboard on front axle (CV Boots Replaced with directions).

I'm curious if there's an easier way if one would like to change ONLY the outboard CV rubber boot. (I know one way is to buy the split CV boot cover, but we have a OEM boot cover handy & wondering if someone has a better way than FSM process which essentially removes the entire axle).

In particular, FSM mention "Do not disassemble the outboard joint" :

Is it because it is impossible to do so? Or just a bad idea for technical reasons?

All we want to do is replace the outboard CV boot cover. So, curious if we should just follow the FSM & take everything apart.

Would appreciate feedback. Thanks!

Despite what the FSM says on that page, the outboard joint is serviceable. The setup of the outboard is the same as a Toyota birfield axle joint, so in addition to the new outboard boot, you will also need a new circlip that goes on the center shaft to keep the outer joint on. This circlip will need to be busted off to remove the outer joint. However, to knock off that circlip, you will need to remove the inboard shaft and inner joint so that you can slide a pipe over the center shaft. See video, though he did not use a pipe:

I do not remember what the part number is for that circlip when I did it, but I’m 95% confident that it’s the same as for the 80 series birfield (90521-34005). @medtro and I have discussed this recently. That part number has the same inner diameter and thickness as the one on the 100 series CV axle. I have a spare axle that I plan to break apart and verify if the above part number is indeed the one that I previously used.

I know separate outboard joint for cleaning is not popular here. I have done a lot of this on birfield. I believe separate the joint is more efficient than spraying a bunch brake cleaner into the joint. This is what I am going to do when I reboot my CV axles.

Thanks JunkCrzr89 and Medtro! Very useful info. This will make cleaning much more thorough for sure.

So once busted apart, you replace the snap ring (C- clip), then press axle back in, compression snap to get started in?

Pipe method by @helocat from Metal Tech. Not 100 series CV axle but you get the idea.

Use hose clamp on circlip to get the inner race started back on to shaft.

if your going to go through the trouble of removing the axle why not just reboot, clan and repack both ends of the shaft and do it right once

Totally agree, will plan to do just that since it'll be out. Time to order more parts!

if you order the boot kit from the dealer it will come with everything that you need, grease, boots, clamps and c-clips

Clean inboard is easy enough.

I agree the brake cleaner is a poor way to clean the outboard. It just doesn't clean well. Better off not cleaning and just adding grease as most shop do, when no contaminates have entered CV.

I use solvent, which cleans very well. But it takes all day of soaking, cleaning out and repeating 7 time to get outboard clean.

Tearing outboard down, would make cleaning more efficient.

Hay I know that guy! (had more hair then) I too 2nd the just toss in a new boot kit from Toyota. $50ish bucks gets you all new boots, grease packs and bands. Do know Toyota does not sell the cir clip, you have to get that from a local CV shop.

I'd try the OEM circlip @JunkCrzr89 posted from 80 series. Toyota does use a lot of parts between models. So good shot that would work and easy too get.
