2004 Ford Freestar wipers?
 

What are the best replacement wiper blades for our vehicles?

I use the original "TRIPLE-EDGE" wipers. Warranted for as long as you own the vehicle. I put them on all 3 wipers in 2005. I get free replacements every spring after winter as the occational wiping across ice tends to nick them up.

I have been very happy with the RainX blades for all season usage.

Mr Use Common Sense, where do you purchase the triple edge blades? I'm sure there are more than just me interested in getting free blades every year.

Here's the MFG (JAMAK IND.) link. Tripledge

I believe that the LIFETIME warranty only applies to the original Tripledge wipers only (Tripledge Windshield Wiper Blades | TheWiperStore.com), not their other wiper products.

You can also get them from here. Tripledge Wiper Blades, Tripledge Wipers, Tripledge Windshield Wipers - Videos, Installations & Reviews

Thank you , I shall look into it.
