Ok so my 04 Rubicon rear axle is leaking at the drivers side seal and the yoke mechanic wants 125 just to do the axle seal ... I can do the yoke but dont have a press for the axle shaft bearing and ring... I've been told that the seal will wear a groove in the shaft and the new seal will leak ...is this true and should i replace the shaft as it has 315000 miles... rearend was rebuilt 4 months ago and been leaking ever since... had words with the shop so I cant take it back there
