    The original axle on my 2008 has a round rubber on the shaft as you can see in this photo:

    I ordered a BRAND NEW (not reman) cv axle from rock auto and it does NOT have that round rubber nor do any of the passenger side cv axles they sell as you can see in this photo:

    I heard on other vehicles that this is to reduce vibration BUT not sure if I am suppose to remove the one off my OEM and install on the new axle or if you are able to install as is w/out that piece or? I def don't want any funny vibrations or issues. I thought I got a defective part but as mentioned, all of their pass side axles for 04-09 Prius do NOT include that rubber piece. I also saw a TRQ video on youtube and the new axle they sell and are installing on the prius does NOT have the rubber part either.

    Planning to install this weekend...

    That’s great to hear. Is the rubber part able to be removed and installed on the new axle or is that permanently attached to the OEM axle?

    From the looks of your picture I'm fairly certain it can't be removed without cutting it off. However if your Prius is in really good condition and drives super quiet then I'd suggest cutting this off and taking pictures of how its built and we can come up with something else to put on their that will have the dampening effect.

    But keep in mind most of these and other sound dampening measures Toyota does tend to be specific to preventing noise complaints when the car is still under warranty. So if your car is making all the usual noises of an old car, there's no reason to worry about one more noise that most people wouldn't notice anyways.

    Here's what it looks like in gen 3, I wouldn't guess gen 2's much different.

    You can take the damper off by loosening the damper clamps and sliding it. But you need to disassemble the joint on one end of the axle to slide it off ... and on one end of your aftermarket axle to be able to slide it on.

    If you're open to the time/labor of joint/boot disassembly, just rebuilding the original Toyota axle becomes a possibility too.

    Can you help us better understand the purpose of that dampener? Does it serve any purpose beyond making the car run quieter?

    I'm sure NVH is its reason for being there ... one of those little touches so it feels like driving a Toyota when you're driving a Toyota.
