Front axle hubs

Our 1998 u295 has oilbath hubs  Does anyone have preference grease vs oil  Would think oil hubs need to roll more often when being stored

The design is for heavy oil.  75-90 or 85-140 is commonly used.

I run a Semi Fluid Grease #4 in my front hubs. It is a synthetic tacky, flow able grease. Available from many sources on the inter web. Designed specifically for non drive type hubs.

Not sure what you mean by "oil sample",if your not sure how long the oil has been in there,change it with new oil,get new sight glass and gasket s and go for it,if you see any shiney metal particles better get new bearing.

Agreed.  There is a surprisingly small amount of gear oil in both the steer and tag hubs.  I followed Brett Wolfe's advice and pumped out what I could and filled them back up with new synthetic gear oil (same as I used in the rear end).  I wouldn't even encourage you to replace the sight glass or gasket unless the existing was damaged or leaking.  I used a Slippery Pete gear oil pump to pump the old out and the new in and it worked great.  Let it sit overnight and check it again because the gear oil takes some time to settle.

Previous owner had front bearings serviced during break service  4000 miles ago  I'm not sure if lube is synthetic or conventional So if I need to add small amount I would like to know that's all

No problem mixing synthetic and conventional oil if that is your concern.

Best advice is to buy one quart of synthetic 80/90 or 85/140 gear oil. Drain/suck out what is in there and change it out.  Not difficult, but coach must be level side to side and WAIT for oil level to equalize.  Do not overfill.  There is a "ring" on the clear plastic showing proper oil level. 

If the old oil in not clean, change it a couple of times.  If any metal it, have bearings serviced IMMEDIATELY.
