Rear End

<< < (2/2)

That stuff is slicker than snot on glass.  I have it in my transmission and in my rear.  My gas mileage improved drastically after I had that old black 90 weight dino gear lube drained and replaced with synthetic.  It's a messy process if you try to do it yourself though.  I took mine to a Jiffy Lube place.  Seems like it was like $65 bux.
