Obviously, you bought your Rainier because you wanted to buy a variety of special features and fun both impeccably combined into one car, truck, or SUV. It's not a regular occurrence that you find yourself in need of a replacement Main Bearing Set for your car or truck. When your Buick Rainier rolled off the assembly line, it was destined for a driver who values economical pricing in their automobile. The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs in today's marketplace.
Your engine can totally break down from lack of lubrication; resulting in intense friction and heat. The places where the most rotary movement occurs in your engine are where the crankshaft spins through the main bore, and that is why your Buick Rainier main bearings are installed there. These main bearings are made from a composite metal called Babbitt (iron, zinc, copper, aluminum, and more), which is just slightly softer than the forged or cast crankshaft and the main caps in your Buick Rainier. Most bearings are cast with lubrication channels, so friction and heat are minimized as the main bearings protect your internals for, hopefully, the life of your car or truck.
