Why does the oil light come on sometimes? - Boston.com

Have a good repair shop hook up gauges and test the engine temperature and oil pressure reading. The problem could be that the engine is, in fact, overheating, causing both the oil and temperature lights to come on. Continuing to drive with these problems will guarantee more expensive repairs. If the readings are normal, then the technician will need to check the gauges, wiring and sensors/sending units on the engine to determine the problem. They put my truck on a lift and one of the mechanics simply grabbed my rear driver side tire and started pulling back and forth and it was able to slide in and out maybe 2-3 inches. I put the car on jack-stands at my house when I got back from the shop and was not able to replicate the movement of the rear axle. Both rear tires were in the air, I spun them into different positions, put the truck in park, neutral, reverse and drive and I couldn’t get the axle to move in and out like they showed me at the shop. The rear axle is held in place with a “C” clip inside of the rear differential. Some movement is possible but several inches of movement definitely requires some further investigation.
