-   i have a very similar if not the same problem. when in 4hi and above 20 i get a growl/grinding noise. i am certin it is coming from the front end but other then that im not sure what it is. does the front transfer case gets its fluid from the tranny or is that somthing i need to check. it almost seems like the 4wd is not fully enguaged or is stuck in 4lo. there is 0 problem when in 2wd and 4 lo seems to operate normaly.-   bargames
