I cringe everytime I watch Utube and think some dealers probably learnt there as well with the short life some bearing have .
No problem here especially with those marine seals, bearing packing - oh hell I give up especially when these guys are headed at you at 120km/h!!!! There is so much wrong I won't even start

?WTF? "Just give the bearing a quick grease" in all my time as a mechanic I've never seen even the most dodgy apprentice do a bearing like that.
I'm close enough to the ramp that I just fill the hub, no dramas!
hey oceanranger24 i think this guy in the video is related to the guy who did your mates bearings. that video should be deleted as its completely unsafe showing people those practices.
i liked the grass all through the grease and the split pin re-assembled a train smash.
he loves hes hammer.

What harm can it do? bit of dirt, bit of cotton lint, bit of super glue . Only 11000 people have watched it , he has 355 clips of other things and heaps of followers waiting for his next gem of trailer maintenance. I can't find one that I know is loads worse from a few years back but it was even more scarey. To think 11000 people may use this as a guide is terrifying . Funny thing is that if he only read even the scant instructions that come with stuff he would be better off. I'm sure he got a lot of his knowledge of forums as see the same mistakes and myths repeated ad-nauseum. Never underestimate the mechanical inability of the general public and assume they have a clue. Wonder what his day job is?
Super gluing the seal into the hub.... is that a new method ...LOL

SK is that meaning you think supaglue is a good or a bad idea?
I am a bloke who built his own shed, built his granny flat, can do simple mechanical maintenance on mowers etc and yet I am completely stumped by what is good or bad in this whole black art of bearings thing.
Normally that would just mean that I would have a expert do it for me, but I don't trust them at all after two bad experiences and having multiple professionals poo poo the work of others.
How the average joe sorts this out is beyond me.
Having said that.... I would be confident that SpaniardKing would do a good job.

Hey walrus
The bloke in the video glued the rubber seal to the bearing - arghhhhh. No idea what he is thinking. . The rubber seal is supposed to be a tight fit on the axel ( but are a ones size fits all or fits none properly in reality
Best way to learn do bearings is to be shown by someone who has done heaps. There are heaps of little things and tricks that take a age to write down( learnt over years of experience) that a competent mechanic can notice straight off and correct them or understand what has gone on.

The rubber seal is suppose to remain stationary on the axle so why did he try to glue it to the bearing ??

He never did show how to pack a beating properly either, the grease has to get into the bearing not just the outside. The best method I had found for myself is putting grease onto my hand and swiping the bearing onto my hand until it fills up. Messy work, I wouldn't have thought just puttin grease onto the outside of the bearings would be enough to pack the bearing. (I may be wrong I'm not a mechanic)
No, your not wrong. The way you did it is the correct way unless you have a bearing packer tool. ( I was a mechanic).
When replacing the bearing cones and seating them home use a brass dolly not a metal rod as the metal could shatter or chip the cones. Also glasses are a must. cheers Ron.
BUGGER - your supposed to put grease in?
If the rubber seal remained stationary, There would be a gap between the rotating hub and the seal there fore major foul up. Also the seal is pressed into the rotating hub which turns, cheers Ron.
G'day
The marine seals are 2 parts.
1) stainless ring that gets pressed onto the rear of the hub
2) rubber seal that should remain stationary and be a tight fit on the axel. Many people glue it to the axel in the correct position after a test fit to ensure it remains in place and doesn't get pushed out by grease pressure from bearing buddies etc etc
So seal is solid and glued to axel and the polished ring is on the hub. Hub is full of grease with bearing loaded with grease. Wipe of grease around the lip of the seal and polished ring and push the hub on whilst turning it. It should seat and the seal should be firm mated up and flushish to the polished rim on the hub to prevent water and dirt getting in.
Many people have made up tubular spacers to fill the void from the axel spindle step down to correct position of the seal before glueing the rubber seal on it can't move away from the hub. Was done as seals are one size fits all but axels were many different designs and spacings from shoulder to where bearings seated and the seal needed to run.
It is the edge of the seal that seals against the inside of stainless ring in the hub.
In photo below - left rubber seal - stationary - glued to axel / spindle ( edit I had " hub " typed here before- thanks FED)
Right bit pressed into hub and spins with hub.
That's it folks.
PS Crunchy- yep bugger , bugger and double bugger grease on the inside and the bearing but only if you want it to last.
