Anybody check into an offset axle seal? I don't remember if they are made for our older trucks. I have used them in newer years and models. They move the seal lip away from groove of the previous seal.be worth checking into. Speedi-sleeves on axles are tricky to install. You can't use the installer cup...no surprise given the length of the axle so one needs to use a pipe that just fits over the sleeve.then very carefully tap it down and the trick is to keep it going on straight. If you go crooked and distorted the sleeve..start over with a new one. I'm sure this is not breaking news to many readers but sometimes these details get overlooked.if the groove in the axle is deep use epoxy to fill the groove,let it set and lightly sand or file it down before installing sleeve.
