TL;DR - They did not fix my issue but acted honorably in the end. Background: The harmonic balancer on my 5.9L Dakota disintegrated. The Dodge 5.9 has a different balancer to the otherwise-similar 5.2 engine, and also different to the pre-1993 version, which was called a 360. Also, original factory 5.9 balancers were bolted together with the crank pulley, but the current aftermarket ones are a 1-piece assembly. 5.2 balancers are still the old style. Now the story. Westside gave me by far the soonest time estimate of any shop I called, so I chose them. They finished the truck WELL before their time estimate. When I started the truck, I immediately noticed a severe engine shake, just like had started when the old balancer came apart. I suspected they put a 5.2 balancer on, and upon asking, they said they had indeed. They said that they ordered the 5.9 part and that it looked different to my stock part and did not physically fit my engine, but the 5.2 part fit easily. I'm not going to go into the mechanical story they came up with to explain this, but suffice to say it was ridiculous to the point of comedy. I asked to have them try the 5.9 part again, but after seeing one from the Dodge dealer, which looked similar to the one that hadn't fit, they declined to waste more time on it. My speculation is that they were originally given the old-style 360 part, and that the part from Dodge would have worked. That would explain the diameter mismatch they described, but I can't confirm this. I asked Westside to give me a partial discount since I was having to undo and repeat their work, but they stood by their decision with the 5.2 balancer. However, they did say we could talk if I managed to get the 5.9 part installed and the engine smooth. Not trusting any shops at this point, I waited ~6 weeks for my friend to return from his duty as an Army diesel mechanic. I understand concepts, but my hands don't understand tools. Last weekend, my friend finally arrived and very easily installed the 5.9 balancer, which I bought over the counter at O'Reilly's. It fit perfectly. Today, I presented Westside with their 5.2 part and smooth-running truck, and they printed me a check for a FULL refund. Parts, labor, everything. For all the drama and hardship that happened, I have to say I was extremely impressed with that follow-up at the end. I never expected a full refund, but it really dies make my life easier. Without that, this would have been a 1-star experience. That said, I still can't give 5 stars, because of the absolutely outrageous theory of the mischievous crank swapping bandit used to explain the part misfit. No one, but NO ONE has ever de-stroked a 5.9 Mopar while keeping every other part factory-stock. Maybe, MAYBE if it was a hot-rodded vintage Duster and some goober wanted to do a poor boy's 340 imitation build, but not a stock truck motor in its stock application.
