I've done my own front end repairs and alignments for years on my Caminos -no problems with abnormal wear-with the work done in my driveway on, thankfully,flat concrete. About all I remember using was a piece of string,a marking pen,tape measure,ordinary bubble carpenters' level -cut off shorter,maybe ,and some thick gauge sheet metal scrap I cut into four squares for ~ 'slippers' ~ two for under each wheel-- with the sheets sandwiched togeather with heavy grease. oh-and a helper to push the truck.
