Anybody know the purpose of this bolt on the bracket..

My guess is that it keeps the bearing from rotating in the carrier. Why it has that plastic tit on it, IDK.

The bolt is rubber tipped and in addition to keep the bearing from rotating in the carrier as suggested by roader I think it might be some sort of a dampener as well ?

I just replaced the driver's side and passenger side CV axles on my 2005 Sienna. This thread was very helpful. One item that hasn't been mentioned in the CV axle seal on the passenger side. I don't believe that mine had one, but it may have. Wondering if I should have put a CV axle seal where the axle enters the transmission. There is a touch of transmission fluid leaking from that spot. Not sure if it is residual fluid from the change or if there should be a seal there.

 

[Roader]

My guess is that you have a seal installed. Without a seal the transmission fluid would pour out after a few miles of driving.

 

[liftedsienna]

That makes sense. I started to feel nervous when I saw some CV Axles with a seal/ dust cover that was visible on the shaft of the axle when it was installed on the vehicle. Maybe the one on mine sits inside the opening where the axle goes. Probably should have replaced that.

 

[Roader]

Oh, it's missing the dust cover. No big deal. My guess is that there's one on the passenger side to keep rocks and sticks away from the seal when driving off road.

 

[liftedsienna]

No dust cover on the transmission or bearing side of the passenger cv axle. I know it originally had one covering the bearings, but I couldn't get it off of the original axle and the replacement didn't come with one. I could try to fabricate something, but my street mechanic thought it was fine without.

 

[paul r]

There is a dust cover on the passenger side and with replacements this cover can be tapped in to be closer to the axle seal. I made the mistake of not renewing the axle seal when I replaced the passenger side axle and had to redo the entire thing again due to a leak. Done at 150k miles. There is a bearing protector (?), at least on the aftermarket one ( Carquest from Advanced Auto) as shown in the pics.

I have a Journeys Off Road lift kit on my 2005 Sienna. The guys there recommended OEM CV axles... or refurbished OEM CV axles from O'Reilly. I opted for the refurbished. They did not come with a dust cover over the bearings like the original. There was no dust cover on the transmission side on the original or the refurbished axle, and I didn't think about replacing the seal until everything was back together. Contemplating taking it all apart and replacing that seal on the transmission side. Ugh. Do you happen to have a part number / description for that axle seal?

This is it for

06 LE.Passenger side. Took the seal to Home Depot and bought a pipe coupling that fits it. Cannot remember if it was a 1.5 inch or 2 inch

 

[liftedsienna]

@paul r - do you happen to have a picture of the pipe coupling in place on the CV Axle? I am having trouble visualizing how it fits together.

When thinking to replace CV Axle, consider this very helpful insight on Car Care Nut video:

 

[Roader]

When thinking about replacing a CV axle, consider what's wrong with it. If it's vibrating under acceleration, repacking the CV joint with grease and replacing or re-clamping the boot isn't going to fix the problem.

 

[circus]

Please, somebody try this then report back! On other makes of vehicles, I've worked on, the outer CV joint just pops off with a tap of a hammer. Usually while the axle is clamped in a vice. But seeing that the carrier bearing of a Sienna make the right axle removal impossible, why not remove the outer CV joint and replace the leaky boot while the axle is still in the van?

 

[Roader]

But seeing that the carrier bearing of a Sienna make the right axle removal impossible...

It's not impossible. It takes a $10 Diablo blade and a Sawzall and an extra hour of your time.

The most common failure mode for the passenger axle is vibration when accelerating at speeds over 45mph. That's from worn out joint(s). Replacing a leaky boot is not going to fix that problem.

Compared to the driver's axle, the pax axle is really long. Any wear in the CV joint(s) is going to be amplified by that long length.

Destroying the axle doesn't count.

Leaky boot causes the joint to go bad.
Anybody, please report back if the outer CV joint pops off without removing the axle 😉

 

[Roader]

Neither CV joint can be completely removed from the axle by mere mortals. This is a picture from the FSM 😉

Haven't needed to replace the boot on a Toyota so I don't know. Outer CV joints on many other makes have C-springs that when the joint is lightly tapped off with a hammer, the "C-spring" go's deeper into its groove. Allowing the outer CV joint to come off then back on. So until someone tries, we'll never know.

I have heard that Toyota dealers in the rust belt routinely just replace the outer shaft and joint, repack it with grease and slap on a new boot, rather than dealing with getting the inner shaft out of the carrier bearing bracket.
