242 noise

Need some help. When in 4wd under load when I push the gas I get a horrible grinding noise that sounds like it’s coming from under the 4wd shifter, so by the front output shaft/yoke. Drained the fluid and it was perfectly clean and full. Took the front shaft off and drove it in 4wd and no noise at all. Do bad shafts/u joints ever make that sort of sound? Could it be the front output bearing only making a noise with the shaft in under load? Oh and it’s a 98. Thanks in advance for the help.

I’ve got this with my 231 only when I drained the fluid chunks of what I suspect is sprocket came out. Only in high though. Never in low.

4wd Hi, 4wd Lo, or both ? U-joints that bad would be really obviously loose.

A slower and low pitched kind of bang, bang, bang, or a higher pitched really fast grrrrrrrrrrrrrrr ?

No bang or anything, just a grinding under load in 4hi and full time that I’ve tried. The u joints on the shaft ‘seem’ fine? There isn’t any play in the front yoke and it seems to turn by hand easy.

Are you a new XJ Cherokee owner ? The XJ Cherokee 231 and 242 transfer cases make a noticeable whirring sound in 4x4.

I’ve owned 4 XJs and 2 TJs, I know that all make a bit of noise in 4wd. Trust me, this noise is not normal.

Is it like a high pitch, sudden fast grinding? That’s what mine does..
