Grinding noise from rear

[stacaram]

Hi y'all. I have a 2003 Jeep Liberty Renegade Limited that the pinion bearings in the rear end went out we replaced them. I have a 5-speed and when you shift into gears it'll grind but then when you take it out of here at the grinding stops can somebody tell me what it could be cuz I'm not very mechanically inclined on that.

Are you saying it makes a noise in drive but not when you are coasting? Do you get any howling at speed?
