What do you all think. The last few months after a turn I can hear a thumping noise in the front end that seems to follow tire rpm. After a while of going straight it stops. Front wheel bearings feel fine in the air. Front axle u-joints at the spindle have no play (but that is where I think my noise is comming from. ) Now I have developed a gear oil leak on the axle seal on the drivers side. Some times there is a 6 inch puddle after 8 hours, and sometimes there is not even a drop after 24 hours. Question, do you think if the front u-joints are going bad that sometimes when stopped the axle is tweaked to one side (because of bad u-joint) and that pulls the axle over enough to distort the seal and cause a leak. Then sometimes the axle happens to be in a true position when stopped and the seal is not being pushed on (tweaked) and doesnt leak that time? Am I making sence? Bill
