I have the axles out of my 46 1/2ton. One brake assembly looks like diff fluid leaked. In the shop manual it says a special tool is needed to drive in axle bearings - but for the seals is says quote: "the oil seal should be staked in place with a [censored] punch". I don't want to replace the bearings, but as a percaution, I'd like to replace the seals. Can I cut/pull the old seals out, leave the bearings as is, and then push new seals in? Or am I creating possible problems? Thanks!
