    Default PLEASE HELP! RA28 to RA40 diff

    Hey guys!
    this morning on my way to work my diff blew up...
    i was wondering, can you interchange an RA28 diff to an RA40?
    im going to have to stay up till midnight to do it, before going to work at 6am and i really need to know asap if it is going to work or not.
    thanks!
    cheers,
    Kenno

    The RA40 diff housing and axles are wider.. But the centers are interchangeable.

    Yup. Watch out for the ratios, though. They might be different and put your speedo off.

    To check the ratios, you can read the plate on the firewall. It should give you the diff code. Then you can check some of the links in this post:
