Pinion seals.

Discovered yesterday that the pinion seal on the front and back of my truck are leaking. Its an 89 w150. Any advice before I got to change them out would be appreciated.

in a 30 yr old truck, I'd say replace all the seals as long as you're at it. if you do all the work, seal and bearings are overall pretty cheap, relatively. reuse all the hard parts/shims and get a crush sleeve eliminator and its a one day, weekend job.
