Exactly as the topic suggests. What is a 3rd member and why do I only see posts about it with toyotas?

Um, it's a guy thing.
Oops, wrong website!


Actually, it's simply a diff; you know, the heavy thing that contains the ring and pinion gears, located at the end of the drive shaft and bolted to the axle housing.

To elaborate a bit more -
Jeeps and many other axles have a cover on the back of the axle to get at the gears.
Toys, some fords, and a few other have the "3rd member" design where you unbolt 3rd member from the front of the axle (after removing the drive shaft). The 3rd member consists of the pinion, gear housing, and all the gears in one easy to work on package.

AHH okay I get it now thanks!. I was thinking it was a 3rd differential like the AWD cars and vans.

OR....a third member can be in the form of the good looking girl you and your wife bring home from the bar after just the right amount of tequila.....
