Jul 201378000 miUS $600 | Rear pinion bearing went bad(scored in one place) mechanic said it sets too long and the top of the bearing is not covered in the lube for a long period.I think it was a faulty bearing. But hey, the truck is 14.5 years old. | ||
Jun 2018107000 miUS $500 | Replace rusted fuel lines. Fuel filler pipe rusted, replaced everything from the filler cap to the tank. Gas would leak on the ground when fueling at the gas station. Living in the rust belt the tin worm has taken its toll, being a Denali with all the cladding has helped, I replaced the left cargo door several years ago, but that's it for the body. The tin worm has eaten away at the underside. Brake lines, fuel lines and trans. cooler line have been repaired or replaced, brake lines several time (thanks GM bean counters for not using stainless steel) always a fun time when the brake pedal goes to the floor. |
