mikeyost,
The reason I changed my hub & bearings is becasue I was getting the same "WHOM WHOM WHOM" sound you are getting. The noise got worse going around turns in the road.
Made the change and it made 100% difference.
I have a 91 Jeep Cherokee Sport. I need to replace the front driver side Hub & Bearing assembly. Can anyone out there provide me with any instructions/assistance?
Keep on Jeepin'
