Lugnutz, thanks for the input. I've driving a couple hundred miles in the last two days running errands and decided it's time to pick up a bearing kit.
In neutral, it whines. At 40 in neutral with clutch in, really too much noise to tell. I've decided it's definitely at its loudest under load in 5th.
Any tips on a kit that includes the necessary bearings? I've already replaced the input shaft bearings, and made use of a small item kit off ebay that include shift fork pads, two flat bearings, the 15 I/S roller bearings along with several other miscellaneous items.
