Q: Persistent front pinion seal leak on 1995 Ford Explorer

We have replaced the front pinion seal twice now and still have it leaking from what appears to be that area. What is the BEST solution? Do we need to replace the crush sleeve and pinion nut and everything? My shade tree mechanic husband insists we can now solve the problem with a speedi sleeve (because a friend mentioned it), but I am tired of just throwing parts at the problem if it won't solve the problem. Doesn't Ford have a definitive solution for this problem?

Ford no doubt has a solution for this problem if you want them to work in it. I've replaced pinion seals without replacing the crush sleeve but you have to know what position and torque the nut was in when you remove it if you don't want to go therough the crush sleeve thing. You didnt' say what condition the pinion yoke that the seals runs on is like. If the metal's not smooth, if there's a groove in the old deal, the new seal won't work well. The seal can only seal against smooth metal.
Thank you! Your answer was just the ticket. Ford had the solution. And good that you mentioned the condition of the yoke, which was not grooved, so I doubted the speedi sleeve would help. Besides there wasn't one to fit that we could find, thank goodness. As it turns out, the 95 explorer had two different front ends, and mine is the dana 35, which doesn't use a crush sleeve or that common pinion sleeve the parts stores kept selling me. I kept getting the seal for the '95 ford explorer (wrong front end) - close in size, but not good enough to seal. Ford has the correct seal and now I'm confident it will solve the issue. Yay!
