It does howl when i push in the clutch, only when im moving, and the faster im going the worse it is. But it also makes pretty much the same noise when im pulling up a hill in 4th at low rpms.
What i drive is an 87' runner with a 22re and a 5spd. trail gear sas, 5" trail gear lift, tg hi steer, spool in rear, trussed yota axles
