    My new AWD swapped 97 Spyder project is in desperate need of rear cv axles. The inner joints are so sloppy they feel like they are about to fall apart and I get a horrible clanking noise from the rear with on/off throttle.

    I've been reading up on the rear axle availability issues, and think I may have found a solution for new rear axles. I'm not quite sure though, since there isn't a clear-cut definitive topic on this that I can find in searching. These threads are where I found the most info, that leads me to believe I have found a solution that I haven't yet seen discussed:
    http://www.dsmtuners.com/threads/lets-talk-difs.400884/
    http://www.dsmtuners.com/threads/evo-rear-lsd-in-a-1g-2g-housing.467544/

    So, if I understand correctly, the inner cups for 1g and 2g LSD rear differentials are the same. I also think I've confirmed this by looking up the Mitsubishi part numbers for the inner cups (I get MB837361 for left 1992-1999 and MB837360 for right 1992-1999). Can anyone help me confirm this is correct?

    I also believe the 2G outer axles are the same between non-LSD and LSD axles, but the 1G outers are different because they have the bolt on flange.

    So, SURTRACK/TRAKMOTIVE offers new complete CV axles for the 2G rear non-LSD for $65.79 each from Rock Auto (p/n MI8196). https://www.rockauto.com/en/moreinfo.php?pk=5468055&cc=1380439&jsn=387&jsn=387

    SURTRACK/TRAKMOTIVE also offers new complete CV axles for the 1G that I believe are configured for the LSD rear for $66.79 each from Rock Auto (MI8195 left, MI8194 right).
    https://www.rockauto.com/en/moreinfo.php?pk=5468052&cc=1205727&jsn=351&jsn=351
    https://www.rockauto.com/en/moreinfo.php?pk=5468049&cc=1205727

    Knowing that aftermarket axles are not necessarily the same internally as OE components, and that aftermarket companies like to keep things common to reduce costs, I'm thinking I should be able to buy a set of the 1G axles and a set of the 2G axles and swap the inner cups to end up with new 2G rear LSD CV axles. My one hangup right now, is that if it were really this simple, why would they not already offer a 2G LSD axle option?

    At those prices, I'm thinking about being the guinea pig and giving this a try if what I posted above is correct info, then it just might work.

    Well, I guess I'll answer my own questions and confirm we do in fact have a new option for cheap NEW 2G rear cv axles! It didn't quite work out like I expected, instead it worked out even better. Turns out, the MI8196 is the correct axle for the right rear with lsd, so that one is a direct replacement. The only one that needs "work" to be correct is the left rear. It was as simple as swapping the inner cup from the MI8195 onto the other MI8196. All the measurements are an exact match. Then you have a left and right 2G rear axle for the lsd rear and a left over right side axle for a 1G lsd rear. Total cost about $200 plus shipping costs and you can possibly sell the left over 1G right side axle to recoup a little of that expense.

    Now, I will admit these are cheap Chinese replacement axles, so probably only suitable for daily driver status. You guys doing high hp builds probably still need to go with the expensive upgrade axles instead of these. I apologize to those selling the used 2g rear axles if I just hurt your market price!

    I wish you had came up with this a couple of months ago when I was looking for rear axles. I ended up just getting high performance axles because I couldn't find a new or decent set. All I was finding is old junk axles for about the same price.

    Sorry if I am in an old thread, but I can´t find this info anywhere
    In the pic you have uploaded it seems like the axles you have bought are thiner that the oem ones.
    Did you measure that??
    I think it is a very good option for people like me who has an LSD diff and non LSD axles but I´m worry about the HP or torque capabilities of aftermarket axles

    Keep your 2g non lsd axles and non lsd pumpkin. The Evo 3-9 lsd is a direct replacement for the open diff in the non lsd pumpkin. They are about $200 on eBay. Mechanical lsd is better than viscous.
