2006 Sienna steering fluid leak

I noticed the rt. Side steering rack boot on my 2006 Toyota Sienna was oily and split. Power steering fluid level was slightly low. Mechanic says seal is leaking and entire rack has to be replaced. Naturally, the 60,0000 mile warranty ended about 3500 miles ago. Think there's any chance a Toyota dealer would take pity on me? I guess I should call just in case. Estimate to replace rack is over $1,000 which I can't afford right now. What are my short term options until I can? There is a large frame piece right below the boot, so unless I drive on a lot of dusty roads, the area seems fairly protected from road grime. The boot has splits but is basically intact. Leak is not leaving spots on my driveway, so seems to be slow. Perhaps it only leaks when the car is running and steering is used? Could adding stop-leak fluid help? As long as I keep an eye on the fluid level, is there any problem with continuing to drive it for a couple of months? Can it affect tire wear or alignment? I notice there are remanufactured racks online, if the mechanic can save me some money by using remanufactured, are they generally going to be reliable enough quality?
