Help with thumping sound in 4WD
Trying to determine if my NP 205 is ready for rework. In 4wd under any kind of load I get a thumping sound. If I leave the hubs locked and go 2 high, No noise. Front drive shaft has all new u-joints. I put a 4 inch lift on a couple years ago and I can't remember if it made the noise before or not. Running 33 inch tires
Any advice would be appreciated. Thanks, Tim
