two months ago i replaced that wheel hub assembly now its grinding whining any ideas
also if i put it in 4hi its smoothe and quiet drives fine what to do?

 

check the cv shaft make sure the boot isnt torn
could be in the front diff i honestly dont have too much expiernce with those though i just bought my first 4wd 2nd gen

 

If you've just replaced the wheel hub assembly that recently it shouldn't be there. I agree that it may be your cv axle on that side.

 

Go back and make sure none of your Hardware loosened up on you.

 

checked everything hub was bad replaced it no noise thanks guys
