2002 V70 NA AT inner CV boot service, damper

2002 V70 non-turbo, AT, 133k

Both the inner CV boots are torn and need to be replaced. The VADIS instructions say that I need to remove the damper in the middle of the axle (with a press) to replace the boot. I don't want to mess with that and would rather just disassemble, clean and reassemble the inner CV joint, which would allow me to replace the boot without touching the damper.

Is there a reason I should follow VADIS and not dissemble the inner joint? Do folks usually just dissemble for a full cleaning?

I've done the inner CV joints on my 99 S70 with manual transmission. That was a few years ago. I disassembled the inner joint, cleaned it and reinstalled. No issues. I'm not sure if the design has changed much on the 02.

I just want to make sure I'm not missing something.

Thanks.

Bump...

Lots of views, no opinions so far. I have a pair of boots for each axle ready to pick up. Just need to know if I can do this without removing the axle damper on the shaft. That adds a whole new level of complexity as I don't have a press.

Anyone ever change the inner boot without removing the damper?

Thanks.

Hey! I've re-greased 2 inner and outer CV joints on passenger side V70's (on 02 and 03) but none of them have a damper. Is the damper on driver or passenger side?

the passenger side does have bearing carrier but that's on the "inside" shaft. that's nothing to worry about as it comes out of the plunge joint (inner CV I think its referred to as) and the boot sits on the "outside of it. You just need to remove the small piece between the plunger and the rotating joint, if the damper is on there you might have to press it off, if not no problem.

I've done this but I'm not familiar with the damper, can you take a picture of it?

I just found this when Googling a bit I found this, maybe that would help. interesting that one has the ABS and the other does not. If you have an axle with the balanced on the middle part I do believe that has to come off. I'd also go that route over buying a new axle, whether you have to put the balancer back on I'm not sure.

I have done a lot of searching, but did not find that post. There is a great piece of information contained in there:

"the big difference from the manual is the inboard joint is a tripod joint that is swaged so it doesn't fall apart instead of the unretained caged ball arrangement of the MT axle"

My 99 S70 is an MT, and when I did those boots, the inner joint just feel apart because the steel balls are unretained. And there is no balancer on the shaft, just as in the picture on that thread.

I've never pulled apart an AT axle, but now I'm expecting a tripod arrangement that may prevent sliding the boot off on the inner end, hence the VADIS instructions to press off the damper.

On my v70, the left axle has the damper, not the right one. I'll start on the right, see how that goes. Maybe the tripod can be knocked off in a similar way the outer joint can be knocked off with a drift.

My problem is that I don't have access to a press for the damper.

Thanks again!

This sitehas some good pictures of what I was looking at, the tripod thing is inner joint. I didn't remove the tripod side off the shaft but if I remember right both ends looked like they could be removed, and if so no need to remove balancer. I might be wrong about the tripod side but the ball bearing side was just a few taps and off came the whole bearing assemble from the shaft.

I finished the job yesterday - see photos below. A few new things I discovered:

- the tripod gear is held on with a circlip, which is easily removed. This is the easiest way to get a new boot on the axle - no need to remove the damper, as VADIS says.

- an Irwin high-strength metal bit and manual screw extractor are perfect for removing a busted axle bolt.

Let me know if you have any questions.

Thanks.

Here is what the right side looked like before the job. The left was identical. Boot failure on the shaft.

After removal, disassembly and cleaning. No damage - whew!

Reassembled with Volvo OE boots, ready to go back in.

Cleaned up and installed.

And the busted bolt with my extraction tools - got them at my local Ace Hardware.

Well done! I don think you'll regret doing this over reman axle. I marveled over the engineering with those bearings, they must take incredible load yet spin free.... Amazing.

Good job documenting too, well done and congrats! I got the cheap boots for mine, curious to see how they hold up.

Hey, great writeup. I'm in the same position and will use your guidance and findings here however before I break out the metal-file, I have what should be a simple question: how did you remove the inner shaft/rollers from the housing. As you mentioned, it's held in by swaged lips - did you just hammer these out so that it would come free (I assume so since I don't see any other obvious solution) and if so, did you restore them or just let it be using the boot to keep it together? Thanks in advance..
