Hey guys, just need some advice on the 99' 5.4l auto 4x4 with 175k miles. I have not bought the truck yet cause I'm curious on what I should look out for. Is it common for 99's to have this many miles? How reliable is the 5.4? and what should be replaced around this area? What have your guys found out about the 5.4 with these many miles. Thanks in advance.
