95 T100 front end rumbling horrible noise, help!!

[95 T100 SE WI]

New to the site, never posted on a forum before. I have a 95 T100 v6 4wd. Owned it for about 6 years now, replaced a few parts 2yrs ago: front axle half shafts/cv joints, upper & lower ball joints, pitman arm, idler arm, brake lines just to name a few.

Im experienciing a loud kinda rumbling noise in the front end when in drive (2wd or 4wd). I can feel it on my feet & cant tell where its comming from. I took it to my buddys shop, put it on the lift, had it in 4wd & went about 15mph & it didnt make the sound i described. He mentioned my inner wheel bearings are shot, as well as my carrier bearing from the rear driveshaft.

when i did all that work 2yrs ago on the front end, i did repack the outer wheel bearings,

IF my inner bearings are shot, & maybe without the weight from the truck on the tires, (when i had it on the lift) could that be my problem? Also i made sure my transfer case had proper fluid level. Any help would be greatly appreciated!!!!!! dan

It would be easier to just pull the inner bearings and do a visual inspection.

Of course...you could just replace the wheel bearings just to make sure.

According to yer other post...did you put ATF in yer transfer case? It should only have 75W-90 gear oil. I'd have yer transfer case double-checked fer damage...

I know in some extreme cases they put other oils in the differential during the super cold winter months but I don't know that fer sure.
