idle arm life expectancy on a 99 tahoe

[anneedstrom]

I have a 2WD 99 Tahoe and I love it. 225,000 miles and it still runs great, not to mention its one of the most comfortable rides ever for a road trip. However, I have had to replace both the idle and pitman arm twice. I bought it at 50,000 miles and they seem to go out every 70,000-90,000 miles.I've just been told I need to replace my idle arm again. Is this common? Do they wear out fairly consistently? How can I prolong their life?

They do wear out fairly often.... best way to keep em in good shape is to buy top quality parts and keep them greased. I have seen them last a very long time with regular greasing, problem is that most quick lubes don't even know there are zerks hidden up there!

Moog has made some problem solvers for replacement but at 70-90000 that's not bad.
