FAQ
What does the pitman arm do?The pitman arm connects the steering gear box to the center link, transferring steering movement from the steering box to the front steering linkage.
What are signs my pitman arm needs replacement?
Common symptoms include steering play, wandering steering, clunking noises when turning, uneven tire wear, or difficulty maintaining alignment.
What does 3-groove / 33 spline mean?
This refers to the steering gear output shaft configuration used on many GM HD trucks. The pitman arm must match the exact spline count and groove pattern of the steering box.
Is this pitman arm greaseable?
Yes. The MOOG K6654HD includes a grease fitting which allows periodic lubrication to extend service life.
Does this help steering looseness on Duramax trucks?
Yes. Worn pitman arms are a common cause of steering play on 2001-2010 GM HD trucks. Replacing the pitman arm restores tighter steering response and improves front end stability.
