Rear main seal advice

2006 4.0 L 150,000 miles. Two months ago on a Baja trip the rear main seal began to leak. After this length of time it is still a minor annoyance, one or two drops per day. I presume the relatively inexpensive seal costs a bundle to have installed. Could this turn into a gusher overnight? Any experience in letting it go for awhile?

If you fill it weekly I don't think it would hurt much. Why not replace the seal though? It's pretty easy and would take 2 hours at the most.

 

Mine is leakin now any input on what I should do

 

How do you figure it's only a 2 hour job? Its not a split seal, and you couldn't possibly R+R the transmission and replace a rear crank seal in 2 hours.
