3x locked '93.
Went on a trip with the family today. About 1.5 hours roundtrip. Some highway and some gravel. On a flat, smooth gravel section without turning, we heard something sort of like driving on washboard, or where they cut grooves into the road to wake you up.
On the way back home, more flat, gentle gravel, it happened several more times. It would start and go away in a few seconds. Didn't seem to be totally speed dependent, but seemed to only happen around 20-30mph. I slowed down some and it appeared that the pitch of the noise changed with engine RPM.
It's pretty random. I have my shop floor taken up with a tractor and need to drive to town tomorrow (2.5 hour round trip.) My concern is that the noise might be differential, transfer case, or transmission related. Maybe birf related? I don't know.
I poked around with a light and couldn't see anything obvious. I don't see what would come up randomly like that, go away, and come back. Only under the mildest of driving conditions.
Engine sounds great. Car handles fine, brakes work, etc.
Would appreciate any help you can offer on such short notice. Debating if this is worthy of trying to swap radiators with the FJ80 tomorrow and taking it instead.
I don't have a lot of concrete "it felt like this," but I applied brakes briefly and it felt like it pulled, maybe to the right, then it tracked normal. I don't know. The noise though is concerning and doesn't match road conditions. Doesn't seem like something is just touching the tire. Handled smooth on some twisty roads and the highway. It's weird.
