ACDelco Professional 45C1123 (19136508) Steering Linkage Idler Arm

AC Delco Professional is the way to fly. The idler mount, arm, and pitman arm are only about $60 total more than the same parts in the ACDelco Advantage line, but the Professional line is much beefier. They work for the GMT 800 trucks. Strongly recommend the OTC 6496 Close Quarters Pitman Arm Puller for Truck/SUV, given the frame on these trucks; that puller is the best $60 your may ever spend. In addition to stopping the tire wear issues with the old idler and pitman arms, this made a huge difference in the ride quality of my truck at highway speeds! I used Mystik JT-6 Hi-Temp lithium-complex grease to lube them up, and all the ball joints and tie rods. It's a high temp grease for wheel bearings, but cheap and has killer specs (they do list it as a chassis grease).

Fit on 2005 Hummer H2. I initially went with the Moog but the Moog wouldn't fit in the mounting frame without modification. This fit perfectly.

Seems to be a solid well built part which should last a while - I made the mistake of buying cheaper front end kit made by Detroit diesel which lasted less than 5k miles ! Should have purchased the oem quality the first time around and saved myself twice the headache of replacing these parts ! Lesson learnt !

OK

I tried Proforged and Moog (which turned out to literally be the same thing as far as anyone can tell) and found the idler arm rotation on them was so stiff it bogged my power steering down. I had to use my entire 200 lbs. body to get the idler arm to rotate once mounted to this such that I can position it for install. That's not right at all... makes no sense. It shouldn't be much stiffer than rotating the steering gear box itself. So I returned those and tried this one and, for good measure, used the ACDelco idler arm. Finally I have my power steering back again. And, yes, I checked my pump. It's fine. And I'm not about to use a reman if I don't need one.

This is a great quality part. It was pretty easy to replace and fit perfectly in place of the original one on my 05 silverado 1500. Cant beat the price also

not completely sure if this is a true acdelco part, or if their quality has gotten this bad. the remove greese zirk fitting isn't usable because it doesn't even have the correct thread count! I doubt there's anyway to get the correct adapter without a full return, and maybe getting lucky with another part.

My nearly 20 year old truck drives like new now after rebuilding front suspension with 190k miles. With a new set of Cooper Tires I still enjoy driving this truck. I'm in process of fixing a few things to do a cross country month long trip to see the west towing a small 20' travel trailer.

Very good product and easy to install

As described. Perfect fit. Seems like gd quality.

Worked fine
