Measuring Driveline Alignment
Engine and driveline swapping has long been a staple of building performance cars since the first rodders began swapping parts in the back of a blacksmith’s shop. Today’s market is full of LS swap parts, upgraded transmissions, and a myriad of rear axle opportunities. But along with all this parts customizing is the reality of ensuring all these parts work together, so your upscale machine sings along nicely on the highway.
One area that is universally overlooked is the link between the transmission and the rear axle. Sure, you spec’d the length of that custom driveshaft right down to ⅛ inch and it now fits snugly in between the engine and rear axle. But is the angle correct? Just because the driveshaft doesn’t vibrate or rattle the inside rearview mirror off its mount on deceleration doesn’t mean the driveshaft angle is correct. It’s really something that should be verified.
To minimize the confusion around measuring the driveline operating angle, TREMEC has come up with a slick smartphone application to measure and compute the operating angles for you. It turns out that a proper operating angle has a very specialized set of requirements.
