You got it, another trailer thread!

Alright folks dummy this down for me. I just found that I've got a rear seal leaking, oil all over the inside of the front starboard wheel. I am going to attempt to make this repair and have looked through several post on here about parts which has helped a bunch.

So you walk the cap off with a mallet and a 2×4. Take the cotter key out, nut retainer & nut, and outer bearing out.

What holds the hub on the spindale!? (Keep in mind this is my first attempt)

Then inner bearing, rear seal, and o-ring comes out.

Thanks!

This isn’t rocket science, but it’s not a trivial thing to do. Tighten the bearings wrong and you’ll end up losing a wheel.

The nut is what holds the whole works together. When you take the nut off, the whole thing will just pull off. If you have brakes on that axle, things get much more complicated.

[rammerjammer]

No brakes. And I believe the nut is 18 to 20 in/lbs or hand tight based on the literature i just read.

But thank you, that assured me how it works!

You have to tighten by feel to get minimal play.

I was always told to tighten it down pretty good, then back the nut back off a little and just snug it back up

[rammerjammer]

Thanks again guys. This has helped get my mind wrapped around how this works.

I just did this last week. Not as bad as I thought. Make sure you have a drain pan under the hub when you get the cap off. The rear seal was a pain to get out. Don't forget to use red RTV sealant around the new rear seal just before installing it into the hub. When you are ready to install the hub make sure you snug the nut while turning the hub (20 ft lbs) This helps seat the bearings. Then loosen the but and then hand tighten it. Also wait about an hour before putting the grease in (cure time for the sealant).

I replaced rear seals on two of mine a couple of months ago. Forgot the RTV. We’ll see how long before I’m doing them again.

just for reference, for you guys who have serviced theirs did they all or any have the hole for the Zerk Fitting?

[rammerjammer]

Yes, I'm looking at mine now.

[fishin couillon]

Why do you need RTV sealant if the seal is suppose to keep water out grease in?

[krindgen]

Tightening my nuts down correctly had always scared the crap outta me. Can't use a torque spec. All by feel......nuts.

I think you kin put a bead around the outside? I'm thinking tit's a lot like the old Ranger COOL hubs.

[rammerjammer]

Is it safe to say the o-ring Marine Master sent with the race, x2 bearings, and cap is for the ring that seals the cap to the hub?

When I took my hub off the spindle, the race was a pain to get out. I put a screwdriver under the seal to try and pry the race out and there was a o-ring between the bearing and race. I finally got the inner bearing and race removed and grease cleaned up but noticed the o-ring for the cap was still in the groove.

One 70 mile round trip to the lake and one is leaking. I must have seated it wrong. I was surprised it leaked. I’ll need to redo it and won’t forget the RTV this time.

Not sure but there was one on there when I removed the original. I agree with your question. I have replaced many rear seals and never used RTV.

I think it is because the grease turns to oil when hot and RTV will make sure the oil does not leak out.

Yes. They did.
