Myco wheel hub lubing
The prev owner told me once a year he would buy a different color high-temp grease and pump it in until the new color started oozing out. That would let you know you had flushed out all the old grease. Sounded logical. Picked up a pneumatic grease gun and a couple tubes of the Mystic red stuff and let it rip. Went thru a whole tube pretty quick.
The front axle has drum brakes and rear axle has no brakes.
When I insert grease on the 2 front hubs, it fills the cavity where the grease fitting is and then overflows all over the grease gun. What came out was some thin and runny gray slime. Made a hell of a mess. Got a couple of handfuls of the gray matter out of each front hub.
On the rear 2 hubs, the newer color grease came out the back side pretty quick but none fills the cavity where the grease fitting is. Saw only a small amount of gray slime come out the rear.
Do I have bad inner seals on the rear 2 hubs??.
Thought maybe the front hubs (with brakes) have something that holds the rear seals in; where on the rear hubs the seals can get pushed out...

While you are pulling everything apart, I advise putting Timken bearings in there as well. They are the best on the market.
Personally, I don't care for my pneumatic/compressor powered grease gun. You can't "feel" anything as in the resistance of inserting new grease. I don't even think mine works all that well. I like the 'two-handed' grease gun with a solid tube from the gun to the zerk coupler.

Thx for the quick reply. I'll plan on a hub party.
I used to have one of those solid tube grease guns. It was nice for some applications. The one I have had for last few years is the 2 handed lever action type but has a hose and is a pain in the a$$ to lube wheel bearings with. If your planning on pumping a whole tube of grease, the pneumatic model works well.
