Torn outer CV boots, both sides, non turbo 850

Post by **SonicAdventure** » 30 Jun 2020, 09:35

Just got my PA inspection done and they informed me both of my outer CV boots are torn on the axles. Did not need them fixed to pass inspection, and the garage I did the inspection at didn’t even seem too interested in doing the job anyway. He said in the long run replacement of both axles is more sensible than just trying to replace the boots.

Has anyone done this job and if so, what axles did you use, remans, new OEM or salvage? I’m thinking it might be time to do Spring, struts, control arms as well.

Well that sucks!

It is hard to tell if your axles are the originals unless you can by chance find a Volvo label still on them. If the boots have not been bad for long, AND they can be identified as OE Volvo, AND they are not clicking when turned then my preferred option is to re-build the original axles. They are way better built than any re-man units which often are not OE cores, or new aftermarket which are a lottery.

You will find those on here that have had some luck with aftermarket replacements but they are a crap shoot. I had one that lasted less than 6 months (and I don't drive far) and the other just over a year before the boots failed and one vibrated until I re-built the originals and swapped it back in.

They can be replaced without having to remove the whole suspension struts. It will need the lower control arm disconnected (I leave it attached at the ball-joint and just remove the 2 inner pivot bush bolts). So suspension can wait if needed unless the control arm bushes or ball joints need done any way.

If you are rebuilding your current axles, use GKN boots from the likes of FCP Euro. Again they are warranted for life, but they are also the OE supplier.

Your other option is if you want to troll junkyards to find axles, and hope they are good originals with good boots.

Where in PA are you? I might have a set for you that I just want out of my basement!

Not to get your hopes up but they came out of a 1998 non-turbo s70 manual.
I don't know if they are the same as a "non turbo 850"
We'd have to figure that out. But I'm in greater philly area and I'd LOVE them out of my basement .... if they fit.

Oh and I've never answered your question about the job.

I've done both. I've replaced axles and I've rebuilt an outer CV joint.
Rebuilding one was easy once you learned the trick. Trick = they don't go back together the way you'd probably think.

But other than being messy, it wasn't that bad so long as you have some way to hold shaft while you work. I went with whatever FCP sold as boot kit. I think for my application it was Volvo. (ouch)

I just checked IPD's site and according to their database the same axle sets (L and R) fit both:

1998 s70 manual

and

1996 850 wagon (auto or manual)

But we should verify further. I know some models differ between auto and manual.

Check this current post from abscate. He is clearly suffering too much spare time:

Good luck with it being a 96 from his notes. I also think I recall (but check) that a Turbo Axle will fit a non-turbo but not the other way around as the turbo were stronger.

If you have aftermarket axles (they were replaced at some point and OEM axles were not used), then the OEM boots you purchase from IPD, FCP, or Volvo may not fit. The aftermarket, cheap axles may use boots with different end diameters. I found this on my 2001 V70 T5 after I bought a replacement boot. In my case, I was unable to disassemble the axle and purchased new axles.

The NA manual axles should work just fine, that seems by far your best bet, thanks amblerman!

I've done a lot of axle swapping among P80 automatics, 95-98, and the two 96 850s have been indistinguishable from the others. So don't sweat that. Turbo and non-turbo are different but only in strength and presumably longevity, not in fitment.

In going from manual to auto the one thing I would confirm is the diameter of the axle shaft, get a set of calipers on there and make sure it matches the diameter of yours. If so, you are good to go. I'd suggest replacing both axle seals too, where the axles enter the transmission.

And I'd definitely save the axles you pull out, you may never need them but to elaborate on scot850's excellent points, I would say the aftermarket axles are generally crap.

Hey, thanks for the heads up on this. Where abouts in PA are you? If I can confirm that they will for sure fit, I’m def. interested. I’m out in Schuylkill County, near Pottsville, but I used to live in the Wyncote/Glenside area. Email me at [email protected] and let’s discuss further. Thanks!

Hey guys!

I have a 1998 v70 turbo.

Did you figure this out , the fitment?

And are these still available? I need a pass side axle....sure could use one, I'm having all sorts of trouble.

My email is [email protected] ....thanks for the assist and letting me know!
