I noticed some clicking in 4wd and hard rights the other day. I couldnt really replicate it but sure it is birfield. I am still on my OEMs with 380,000 miles on them. Flipped them once at at about 250,00. What birfields are recomended these days? I have a 94 BUT no ABS and it is converted to part time. So that might give me some different options. Is there a particulare brand that is GTG?
