Since I broke my inner front diff axel this past weekend I have been searching options for repair. I found a guy parting out a 06 4WD tundra and will sell me the whole assembly for a great price of $250. I need to remove it myself, no biggie. Is this a suitable replacement for my 99? At the very least can I use the inner Axle?? I am thinking the whole diff assembly is going to be way cheaper than just a inner front axle from Toyota anyways. Thoughts?
