Steering box oil - type ?

[bighealeysource]

Hey all,
Quick question, Moss and others sell an oil specifically
for the steering gear box but based on what I can find in
the workshop manual,looks like 90 weight is called out.
What do y'all recommend ?
Thanks,
Mike

If you have ANY leaks, or just because, I use 140 wt. In general it does not leak and the heavier oil will not cause problems in the box.

I've been using Red Line 80w/140 too, mostly because I buy it buy the case for the BMWs I work on, and it's always on hand.

Since I replaced the lower steering box seal, mine doesn't leak any more either.

Most people seem to recommend the Penrite steering box oil, made specifically for worm boxes, and doesnt leak as its very thick (comes in bottle tnat has tube to squeeze it thru - stand in bowl of hot water to help it flow better):
