...does it need an alignment? My old '85 Toyota has begun wandering on the pavement. I haven't abused it, its got stock springs, shocks, new tires, ,power steering pump , steering box is tight and tires are aired up to the suggested 50 psi.

Yes, the 80-85 Toyota 4x4 have some issues with wandering after 20 years of trouble free service. Marlin Crawler makes a cross over high steer kit, but you will have to change the original steering box over to the 86-95 4x4 steering box, and that requires some welding. here is the link. www.marlincrawler.com

If you're not into that, just replace what you have with new parts.
