whiz, I forgot and someone may have already advised, but when you pull off the floor cover, just set the brake, put it in gear and you will know real quick if it is in this area,,mine went out last yr, luke and others gave me instructions how to replace, mine u joints broke without any prior warning. I replaced mine without to much trouble other then doing it by myself and having to get under the truck many time to adjust the jack, at any rate, mine came out again after 8 miles, don't know why, I replaced mine with the blazer/s10 set up. a mech told me he thought that I may not have tighten the u bolts tight enough, I think they only require 7 lbs, did not have torque wrench, but I felt that I did have at least that much, that isn't much at all and I did not want to strip them out, anyway good luck, hang tough, as you know others will help, you see, I don't joke all of the time,,,,Fred
