100mm CV Axle Questions
« on: February 23, 2019, 12:10:55 AM »
Iíve been researching replacement CV axles and have found several references to the fact that Ď94-í96 3.5 DOHC SRs, and possibly Ď97-í98 3.5 SOHC SRs, have stronger 100mm CV axles vs the more common 95mm Montero/Montero Sport CV axles and can be run with minimal modifications:

https://expeditionportal.com/forum/threads/montero-buyers-guide.157835/page-2



Iím a bit uncertain about what the 95mm vs 100mm measurement actually refers to on the CV axle. Can anyone confirm the picture below represents where that measurement is taken so that CV axles in the junkyard can be positively identified via something other than their year/engine/trim combination, in case theyíve been replaced at some point?



If the picture above is inaccurate, can someone provide a picture or drawing demonstrating where the measurement should be taken?



It seems that in order to be run on the passenger side, the 4 holes of the flange must be ovalized to fit the 4 mounting bolts. While Iím sure doing so is plenty strong, would it be possible to swap the cups w/flanges between 95mm and 100mm CV axles to avoid having to modify the 4 holes to make them fit, as these pics from ADD suggest?






Iíve also found that Milner, in the UK, offers upgraded polyurethane replacement CV boots. Since Iíll be rebuilding and rebooting any axles I pull out of a junkyard anyway, they seem like a good bit of insurance. Does anyone have any experience with them?

For posterityís sake, hereís a tidy tutorial outlining the removal, rebuilding/rebooting, and installation process for CV axles:

As always, thanks in advance, I appreciate any and all info and help.

100 is stamped into the inner and outer cups, also on OEM boots. NTN 100 is typically what it says, sometimes CV 100. The 94-98 Montero with 3.5 or any Gen 2 with manual trans could be holding some never been used CV's in the salvage yard.

I should start rebuilding parts for you guys since side work seems to be impossible for me now.

Thanks Toasty, that makes identifying them much easier.

Do you think refurbishing them would be worth the effort once you factor in the time require to locate, pull, overhaul, ship, etc?

It doesn't seem too hard to find them on car-part.com... I'm thinking of tracking down two pairs and rebuilding them both in order to have spares once I get to that point in my build.

Hmmm... Think the +5mm stretch would prove too much?
