The axle shaft seals that come from parts store or come in the cheap "kits" are garbage , but they are cheap.
Go with marlin eco-seals or trail gear's "trail safe" or whatever they are called , for the shaft seals . Summit sells trail-gear , so you can have shipped to you in a day or two . I cant offer an opinion on the yukon kits , but I agree buy local when possible .
Spend the extra money and get good seals , toyota axles are already messy and leak prone , dont make it worse .
Saving $50 wont be worth it , when your resealing the front axle in 18 months , I should know , I made that mistake twice .
