Freightliner oil filled front hubs??

[1ciderdog]

I doubt the front hubs fluids have been changed on my freightliner chassis and I have about 63K on it and it had 32K when I bought it. The maintence chart refers me to pages 33-05 & 33-06 but my maintenance book ends at 33-4. So anything special I should know about before I drain and replace the fluid with I think 80-90 weight gear oil? Thanks

80/90 gear oil was the recomendation on the B-in- laws ,Workhorse, I'll check F/L web page, and get back if anything different. Pipe thread sealant on the drain plug.

80/90 is correct,

Skip,
Thanks for the information. I did spend a couple of hours this morning between that site & FCOC but didn't explore the downloads you pointed out.

I have a Maxam chassis, I changed the oil filled hubs for 1st time today. My tag axle had 2 drain plugs as well as the rubber stopper in the centre...my front axle I could only find one drain plug in addition to the rubber stopper.

The manual uses the plural form (front hub drain plugs)

Am I blind?

Thanks!!

I don't think so, probably a typeO. I realy can't think of any reason for them needing to have two. Except that you would only have to turn the Hub 1/2 as far to get the drain to the right spot.

Could be refering to Right and left wheel.

OK I think you guys are correct...2 drains on the tag axle one on the front.

One more thing....I changed the oil in the differential....the drain plug is about 2 threads from being flush after I reinstalled it....I can't remember if that was normal? It is torqued to spec so I think it is the way it was.

(quick tip...make sure hole in drain pan is larger than the one you catch 10-30W with !! ask me how I know)

If it doesn't leak, I would say you are good.
