Rear pinion seal

Ok guys looking for a little input/ advice. Had some work done 4 months ago at a shop. Work that I could not do myself, seeing it was there even though I could do this one I had them do the rear pinion seal because it was leaking. 4 months later it is leaking again. I bought a new seal yesterday and put it in. Took it for a test spin and the new seal leaks worse then the one I replaced. I made sure it was put in square and everything else. Any thoughts would be great.

You need to measure the torque required to rotate the pinion with nothing else in the axle. Measure the torque required to remove the pinion nut. Replace seal. Torque to 5ftlbs more than removal torque, not to exceed 275ftlbs. Measure rotating torque again, increase in 5ftlb increments until rotating torque is back in spec for used bearings. Again not exceeding 275ftlbs. If you do you need to install a new crush sleeve.

Replace the pinion nut also.
