Idler arm

There are a number of variables that could exist between the two vehicles. If you are trying to rob a used part from a donor vehicle, this is not the part to do that with. Idler arms are high-failure parts on GM vehicles, so installing a used one is not a good value. You will have the same sloppiness and the same tire wear in short order, then you will be doing the job again.

If you have a new part sitting on the shelf for one vehicle, and you want to use it on the other vehicle, it is easier for you to look the parts up on a web site to see if the same number is listed for both. I use the Rock Auto web site a lot for this. This is where I looked and found you need to answer some questions before I can find the answer for you. Some trucks have rack and pinion steering and no idler arm. For those with the "parallelogram" steering linkage, there are multiple designs, and they use different types of idler arms. There will also be differences between the 1500's and the 2500's.
