Review on ⚙️ ACDelco Professional 45C0075 Pitman Arm: Durable and Stylish in Black by Jack Harrell

I bought this to replace a Moog Pitman arm on my 2003 Hummer H2. The Moog's pivot wore out within 5 years, despite doing little off-road work. I suspect the problem was caused by Moog using a foam ring to seal the grease. This foam ring wasn't stiff enough to hold the grease in the pivot, causing the pivot to dry out. So this time I went for an AC Delco branded part. AC Delco has at least two levels of quality for its parts. ACDelco Professional parts are made in Taiwan and tend to be harder hardened and have tighter tolerances. This part felt better than the Moog part because the lubricating seal is made of urethane rubber that tightly covers the pivot base. I hope this keeps the fat in longer. I'll write more about durability later. Before ordering, please inquire whether your vehicle uses a 3 or 4 groove spline to connect the steering box to the pitman arm. You should be able to see this by removing the locknut from the splined shaft. Part AC Delco 45C0075 is a 3 groove lever and 45C0069 is a 4 groove lever.
