Steering issues...

[nickvig]

Hey guys. My '87 R1500 GMC has been under minor repairs the last few weeks. After replacing the front springs to get it back to stock height and the shocks all the way around I've noticed that the truck tends to wander on the freeway. The only way I can describe it is that it tracks straight but there's a lot of side to side play. I find myself overcorrecting on the freeway quite a bit.

So...in talking to my cousin he said I probably need a new pitman arm and need to look at all the steering components that might need to be replaced. In looking for the pitman arm it's listed as GM Part 14013038

But...when you look at Rock Auto it shows:

ACDELCO 45C0007 {#88911192} Professional Info
Power steering; Except Variable Ratio

45C0007 and 14013038 are supposedly interchangeable but the Rock Auto site specifically states not for variable ratio. My truck has RPO code N41 -- Steering Power, Variable Ratio. So now that you've read this novella....what's the right part number for the pitman arm? Keith? Hatzie?
