Did an oil change and inspection today on my dentist's assistant's 2009 Silverado K2500HD 6.0. 154435 miles. Had to remove the aluminum skid plate to keep from oil running all over. 4 bolts, 15mm head, and easy drop and reinstall. They had been told by another local shop that the transmission fluid was dark and needed changed. The fluid is bright red and clean and full. The transmission cooling lines are leaking but the other shop said nothing. The oil cooler lines are dry. Did not see any other leaks. The other shop said the shocks needed replaced because were leaking. They are bone dry and work just fine. There were numerous other "concerns" and the only thing I agreed with was when I looked under the hood 2 months ago, before she finally got it to me, that the battery was nasty and corroded badly and old and needed replaced. They had a battery store in town put a new one in. The shop said ball joints were bad, there was not any play.
I did hear a noise in the cab, windows down or up, when in reverse or drive at idle. Park or neutral and noise greatly diminished. Mechanic's stethoscope to the rescue. When she got there and could hold the brake in gear at idle, I traced to noisy tensioner bearing and idle bearing. I cleaned the stethoscope ears and showed her where to place the probe and she could hear it too. She had heard the noise in the cab but disregarded it. I told her not an emergency but will be needed soon. Her headlights housings were very clouded and showed her that. She said she thought the headlights should be brighter and now knows why.
She left happy.
BUT. Recently my VA doctor said that based on symptoms of a hot feeling, intermittently in my right groin area and what he felt with his probing fingers, that I have the signs of an Inguinal Hernia and recommended that if I continue to work on vehicles, I will, I need to do the less strenuous tasks and not lift anything heavy. That may put an end to removing and replacing tires/wheels for inspections and brake work. Any heavy steering and suspension work. I do believe my age and years of bodily abuse in the trenches is catching up to me.
That means that my upcoming work on my 2004 Silverado K2500HD, at my friends shop, may have to be a lot of my friend and less of me.
