    So, I replaced my diff with a 2006 Tundra diff with 3.9 gears and LSD. After driving around since Monday I havn't had a problem until today.

    Today I installed a URD CAI and when I test drove it. After mashing the pedel often and spinning tires and all that good stuff, my ABS and VSC lights came on solid. So I turned the truck off, the lights turned off and stayed off. I assume this is from the LSD and VSC not getting along, but I don't know for sure.

    I have never had the lights just stay on as if there was a problem before....

    If anyone has an idea I would appreciate it. Tried a search to no avail.

    Thanks!

    Edit : I've checked all of the wires and all looked good and were tight

    Yeah after I turned the truck off and restart, they have not come back on... Also my ultra gauge was acting weird during that time too. Stayed on scan mode.... Grimlins

    Any thoughts? Every thing seems normal now. I kinda think that the scan gauge was messin with stuff since it was in some weird scan mode when this happened.

    :notsure:

    Don't worry about it unless they come back on. If you really want, go to your dealer and ask them to scan for history codes. Honestly don't waste your money unless they come back on.

    Cool. Probably a fluke type thing.

    Thanks!
