Front end problems

I recently purchased a 1995 Sierra SLE witha 5.7 motor and I sent it out to the local technical college to have some rough idle issues corrected and the teacher mentioned that I have some front end issues. He specifically said that I needed tie rods, an idler arm and a pitman arm. Since they had front end alignments in the early part of the year they would not be able to fix this for me. Is there somewhere online that could get some diagrams and instructions to possibly due this repair myself and take it in for an alignment when I am done. I am fairly mechanically inclined but am I biting off more than I can chew. The truck is a extended cab with a long bed and 2 wheel drive if this will make any difference. Thanks in advance, Phil Wolf
