In my 93 V6 4runner i am recently noticing an odd driveline vibration and noise as the tacho passes through the 1500rpm range. It happens in any gear at these revs. I am thinking it is something clutch or gearbox related? Would a shagged pilot bearing have symptoms like this? Faster or slower than 1500rpm and everything seems fine.

possibly the harmonic balancer?

ujoints/driveshaft

He said it happens at same rpm in any gear, so it wouldn't be the shaft/ujoints.

My vote is harmonic balancer or throwout bearing/clutch is going out.

Have you check your belts/accessory/idler pulleys? May be a bearing goijng bad...
