Vern Tardel and maybe others have made a tube type baffle that can be installed in the torque tube that dams the oil in the tube. When cars have a rake up in the back with the big & little tire combo, the oil will flow that way. The baffle will dam it up but you have to park up on a slope now and then to get it to drain back into the rear axle housing. Vern advertises his for $55. You can see it on his web site.
