    This may be a rookie question but popped the check plug off of my front differential and real thick yellow fluid just started pouring out.:eek1:

    Is there yellow fluid or is this bad? Also I thought that the fluid level should be just under the plug:doah:

    Thoughts:thinking:

    Holy crap you have a yellow overflow situation..................!!




    Nope that is normal. Once the G80-90 get spun around it gets a litte more yellow from the air bubbles in it. And having too much in the diff is not a big deal.

    If you checked it when it was hot that would account for the spilling out as the oil when hot expands. The oil will also be airated if checked after just having driven it so that would make it appear yellow in color.
