300U Steering Shaft Leakage

My 300U with power steering has leaked lube oil from the steering shafts since I bought it--even after replacing the seals (they are installed correctly) and switching to SAE 140 gear oil. Would using "speedy sleeves" or whatever they're called on the steering shafts be the best route for solving the leakage problem? I'm guessing that the shafts have worn enough where they contact the seals to allow lube oil past them.

The power steering seems to work OK, not sure how good it was when new, so I don't know if it is worth trying to pull the steering unit out to fix shafts and reseal the power steering. What has anyone else done, and what parts are even available?
 
Get a replacement seal that is either narrower, or wider than the original, but has the same OD an ID.
Clean the shaft, and polish it Roundy round, with 600 grit SiO2 paper. The new will land on a different spot, and be fine! Liube it with a dab of engine assembly or synthetic grease on the install. JimN
 

Hi, Kerwin.

First: Jim N. is right, as usual.

As another option, you may want to check the archives for discussions regarding using corn head grease rather than oil as a steering gear lubricant -- provided you're talking about the steering gear box; it sounds like you are.
