After changing my serpentine belt a couple of weeks ago, I realized that I'd never changed the idler pulleys on my '98 ZJ 4.0L. I figured at 170K it was about time
. I'm planning a trip to Baja some time over the next few months, and want to minimize the possibility of preventable breakdowns. Originally I was planning on using a Dorman part, because I like the company well enough to own some stock in it. Every little bit helps. I asked the person at the counter whether he knew where they were made, as I was comparing it with the Gates brand part. He was "pretty sure it's US made." I found out it was actually made in China, which disappointed me as a quality hound, but realized they're in a competitive field where it's basically necessary to seek out cheap Chinese labor. The Gates was made in Canada so, despite it being 2X the money, I went with it. Gates claims that they are OE designers, etc., and have actually taken Dorman to court numerous times for similarly made claims. This may be true, but the wheel casting is considerably thinner than the Mopar one I removed. I'll have to trust that the Canadian made part has a better bearing, as that's probably the most important part. Super simple job to replace it. Truly 5-10 minutes.
