multiple universal joints

U-joints are a small, simple component - in fact, they have changed much since the very first automobiles. However, on any vehicle with a driveshaft, its ability to move depends entirely on the u-joint being there. You’ll often hear “maybe it’s the u-joints” as a solution offered for problems with a vehicle - but what are they, what do they do, and how do you know if yours is bad? Harold's Used Auto Parts Inc in Philadelphia, PA has the answers.

Air. Air in the system causes all kinds of issues, from hard starting, poor running conditions, or an engine that won’t run at all. If too much air gets in the system, the fuel pump won’t be able to deliver fuel, and the engine will stall, die, or fail to start.  Air enters the system via a leak or a bad seal - a deteriorated o-ring, worn component, faulty hose, or otherwise. Here we inspect your lines and connections to ensure they are in good shape and track down any leaks we notice air in the system.
