Very distinct hum after installing adj torque arm?
Just finished installing an adjustable torque arm and now there is a very distinct hum at only a certain rpm/load that was not there before.
I adjusted it the best I could to have what I think is -1 degree of true pinion angle.
Could this be the cause of the humming noise?

Re: Very distinct hum after installing adj torque arm?
What brand arm? Does it now attach to the floor, instead of the tranny tailshaft? Does it have a poly bushing or a rod end?
If its a rod end and attached to the floor, you're bound to hear every noise the rear axle makes. Comes with the design of the arm.

It's a Spohn that connects to a tunnel/g-load brace with a poly bushing end.
Main thing was wanting to know if its normal or if the humming noise is an indication that the pinion angle was not correct and causing driveline bind?
Everything else feel normal.
