Part Comparison: Old Idler Arm vs. New MOOG.

Idler Arm Comparison.

Over the past 6 years, I have slowly but surely replaced the majority of the steering components on my truck. The latest part that I swapped out was the Idler Arm. Mine was totally smoked, and may have even been the original one that came with the truck 22 years ago. As you can see in the picture, there is nearly zero bushing left inside where it attaches to the bracket. I am sure that the fact that it was ungreasable lead to its demise, but it was the gigantic car launching pot hole near my house that really finished it off. Let’s hear more about it!

In the moment before I hit the unavoidable paved crevasse that was racing toward me, I began saying “oooooohh” very loudly and immediately clamped my jaw shut. I figured that if I did this, maybe I wouldn’t bite my tongue off when I rolled my truck deep into the nearby woods while on fire. I then double checked my seatbelt, and began mentally preparing for impact. The mating of my right front wheel with this hole in the road, was time bending. In reality, it may have lasted less than 1 awful millisecond, but it felt like an eternal sentence in Destructionville. Oh gosh the sound was atrocious. Imagine what it sounds like to crash a medieval castle into an equally large, yet fragile, glass tank full of anchors. That is close to the sound that my truck made when contact was made. Each and every part of my truck separated for a split second and then came crashing back together again. When my brain turned back on and all wheels were touching the ground again, I was miraculously still driving down the street. I pulled into my driveway, twitching just a little bit, and noticed a fantastic new clunk in my steering to track down. Alas, the idler arm had given up the ghost.

With a bunch of different brands available, I decided to spring for the MOOG brand replacement because I know how much effort goes into the making of their high quality steering and suspension parts. When I opened the box, I was not disappointed. This new idler arm was an absolute beast from Awesometown.  It looked like it could have eaten my old idler arm as an appetizer and then asked if the steering box was the main course. Both ends of it were greasable, and the arm itself appeared far more heavy duty than the original. I can’t be sure, but my instinct tells me that it was likely cast with the finest iron ore in the world, possibly found hidden beneath a prairie full of unicorns. The bracket that it mounted to was all business as well. I didn’t measure it, but I would guess it was at least 1/4 inch thick, maybe even 3/8ths, and it was also a cast piece. The bracket did have a different shape than my original one, but I imagine it is so that it can be used on other vehicles as well.

I bolted it onto the truck, and it fit perfectly, just as I had expected it to. It came with a new castle nut and cotter pin, which all fell into place. The total job was easily done with air tools, and nonchalantly took me about a half hour to do. The steering in my truck has honestly never felt better, and it is far less scary over bumps. This job has really reinforced in my mind why it is often worth it to spend a few more dollars for the MOOG brand. The other lesson to be learned here is to avoid the time-bending pot holes, because they will destroy your vehicle with the quickness.
