1992 FJ80 216,xxx miles. 2.5 OME lift
About 6 months ago I did some light off-roading, and the next day I heard a slight metal scraping sound from the front end when I was leaving house. It only happened at low speeds when accelerating and went away when I let off the gas (I have never heard it when going in reverse or neutral). I was assuming something may have gotten bent. I checked the brakes, drive shaft, etc. to see if anything was rubbing, and didn't notice anything out of the ordinary. I took the front wheels off to inspect the brakes and replaced the front brake pads just in case. Also changed out the front diff, tcase, and rear diff fluids and didn't notice anything bad (metal shavings). The noise lasted for another day or two, then completely went away...
It just came back much louder this last weekend on a ski trip when I had a full carload of people, gear, and about 2-3 feet of snow on top of the car. This time it was almost every time I accelerated at low speeds/gears, and the sound would react with how much gas I was giving it. Seems to be fully related to RPMs. I attached a link to a video that I was able to get with the noise this weekend. I noticed the sound would even happen when I was in high gears going faster when I would hit a bump in the road. Does this sound like something is rubbing on the driveline like the exhaust or something? I'm really hoping this isn't a tcase or transmission issue, but any ideas would help!!
Also for reference, I did have an issue with the spindle bushing a few years back and fixed that. This sound is completely different from what I was experiencing with that.
Cheers!!
