Default Mild driveline whine after lowering

just wondering if anyone else noticed this...just lowered the car with Steeda Sport springs (mild drop) but now i have a slight (not annoying) whine at 75-80mph...sorta quiet, definitely sounds like it is coming from the driveline, not noticeable at lower speeds but constant on the highway....is this due to pinon angle change from the lowering?

Just wondering if i (now) need to also get an adjustable UCA to reset my pinon angle to eliminate it (???)

thanks,
dh

Since you still have the OE LCAs and UCA, try loosening all six rear control arm bolts and settling the car by bouncing it and perhaps rolling it a few feet before retorquing them. You'll need ramps, because the retorquing must be done with the wheels fully loaded with the car weight. This will remove all or most of the stress that you put the bushings under when you lowered the car, which I think makes them transmit sound better (obviously not what you want here).

The noise itself was probably always there.

Sounds like gear whine and your pinion angle may be off from lowering, what Norm suggested should fix that issue...

Just get a louder exhaust. Fixes all sorts of weird noises.
