I made this modification as the article instructed. Factory shim was .017"thick. I enlarged the ID hole of a 1/2" washer by holding it in the jaws of a vice grips and steping up in drill bit sizes to get to 3/8". Modified washer was .062" thick, added to factory shim for a total of .079". ( The article stated the slant 6 shim pack totaled .077")

I realy can't say I can feel a differance in steering effort. My steering box may have over 100,000 miles on it. I can understand it may be a little loose but I thought the effort level would increase and be felt.

I didn't post my findings as I didn't want to cast doubt on the article. The article made a statement regarding worn boxes in the first paragraph.

It is an easy modification and I hope others will post their results and the total thickness of shims used.
