I have noticed this mild noise coming from under the D1, 1997, and today i crawled under and played with the ball joints ect and found nothing, while in foreward or reverse, i cannot stimulate the noise, brake,gas, ect, but when under the truck, i rotated the rear drive shaft and nothing, rotated the front and NOISE, only once, i can only hear noise while driving 5 mph or so with window down, it sounds as if you stepped on a pencil and broke it, a mild thunk, mabey like a wad of ice on a wire in the wheel well tapping the fenderwell, this noise can be felt through the truck ever so mildly, what could it be? is it this $ or what? the truck has 90k miles, no transfer case whining, or jumping out of 4wd, i dont know if it does this with 4wd engaged, and advice????? i will change fluid tomorrow, and i do change all drivetrain fluids about every 10k miles! Peter. ps I'm scared! | ||

Update, changed fluid, no shavings on magnet, oil very clean, still makes noise in drive and neutral @ 5-15 mph, in both awd and 4wd, What is it? a broken tooth? this noise started after several hours in 4wd in 15+" of snow, Peter | ||

Is it maybe a busted U-joint on the front D/S? You sure it is from the t-case and not the front axle? Ron | ||

If you say all drivetrain fluids.. how bout the diffs. I've heard of the spider gears wearing out and would be consistent with your diagnosis. Drop the front d/s and put in lock and see if you can still hear it. That would be a way to verify front. Also you can check the U-joints as well. | ||

All fluids means, f+r diffs, transfer case,and auto box, i do this about every 10k miles, or the day after deep water crossings! i have yet to find water/foam in anything, and i also, while under there grease all grease nipples, (f+r splines, all 3 u joints) i will try to pull f drive shaft and try again! and yes it does seem like the noise is internal! u joints are tight and no play in splines, and cannot, with hand, move yolks side/side, or up/down, I'm plum confused!

After looking at the pic in your profile i see that the truck does not fear water. Have you drained the swivel housings? The noise could be from the CV joints. Just a guess but i did not see the swivel fluid mentioned |
