I called my local NAPA parts store and they have 2 bearing kits for me. The kit includes cotter pin, gasket, inner and outer bearings. I will also need some additional grease.
A 2009 trailer should not need the bearings replaced.. A spare set perhaps? Also don't forget the seal. Like you, I had never done bearings until I got my first trailer. I stuck with the Dexter manual. It even recommends the grease to use. Good luck, Raz

Greg,

Thank you for verbalizing what I have thought for a while about the frequency required in repacks (I just didn't want to say much as a newbie)...
I see both sides... as far as I understand it, car axles from the manufacturer are far tighter sealed, and less likely to dry out or have issues- so of course they shouldn't need to have that seal un-necessarily broken and exposed if not needed. But, cars get a lot more miles than our little scamp will. To me there seems to be a balance of common sense and precaution here.

In our journey home after buying the camper (if you followed our original thread, which I believe you have) we were concerned about getting home without the bearings being replaced. We talked to a mechanic at a Love's Travel Stop and he talked to us about heat buildup- so, we at least started hand checking the heat of the axle at each stop to see if it felt hot to the touch. Not the most accurate method i'm sure, but it did give us some consolation in our trip home of possibly being able to detect if we were on the verge of a disaster. I have read that some people carry a laser heat gun and check the temp that way while driving. Overkill?

So Raz, you are suggesting I clean (and inspect) the existing bearings and repack? I was just operating under the assumption of "If I am going to bother to disassemble, I might as well put in new parts since they are cheap"....

If they are those "blister pack" bearing kits, I'd tend to shy away from them. They are notorious for being made from very inferior quality materials. FWIW, I would rather buy a good set of Timken bearings and races in lieu of those "pre-packaged kits".

Also, a good set of bearings, (Timken,) along with the associated races and seals, will run you close to $50.00 per wheel for the complete set. If it ain't broke, don't fix it.
Clean them real good with Kerosene and repack them by hand. If they're in good shape, why replace them? It wouldn't hurt to have, and keep, a spare set in your travel kit just in case, but I wouldn't just replace them to replace them.

If the bearings have been properly serviced, yes. I do mine yearly. There is usually a little contamination at the seal, the rest looks like I just did the job. On the other hand, if I found dirt, burnt bearings, etc, I'd replace them. At 30k I redid my brakes . I bought a brake plate and a drum kit. The drum kit came with new bearings and races already installed. So at 30k I got new bearings not because I needed them but because the kit came with them. The old bearings are in a baggie, greased as suggested. Just in case.

You don't say what year your Scamp13 is or if the axle has been replaced.
Do you have brakes?

Yup, it is possible to buy grease that is incompatible with what is in there now. I buy the exact brand name and type that Lippard (my axle maker) suggests just to be safe.

And as for replacing bearings.. well it does save you from the dirty job of cleaning the old ones. Might even be worth the cost to some people. But remember that if bearings get changed, so do the races.

Alas there is more to doing this right than first meets the eye but its not that hard once you get into it.

Floyd, it is a 2009, original axle.
Sounds like I should just examine my existing bearings and repack as needed. I will still head to NAPA or advanced auto parts and get some grease and a few tools. I might pick up one of the cheap bearing sets to have as a backup on the road as an emergency, but not intended for long term use.

Thanks for the suggestions.

In one of the 1st replies someone posted a great link with pictures of what to look for in terms of bearing damage/wear. I will use that as a guide and post pics if I find anything questionable.

Do I need to call scamp to find out the axle manufacturer in order to get correct grease?

Floyd, no brakes.

.
I'm pretty sure you have a Dexter #9 axle. That's what Scamp was using in 2010 when we were shopping. Look under the trailer, you might find a label on the axle about half way between the wheels.

One thing you might want to get is a short piece of 2" PVC pipe. It will let you install the dust cap without denting it. If you can't find a piece, Home Depot will sell you a 2 foot piece and if you ask nice they will cut it for you.

You might not might be so lucky since your trailer has some age on it.. but its worth a look.. this a photo of my axles label that I took as part of the initial inventory of parts.

One other thing. If you do get into replacing the bearings, you need a new pair of seals. It is quite probable that the seals will not come out easily and will get damaged in the process. My recent experience.

Also, I agree with Greg that the bearings do not need to be replaced just because they are several years old. Boat trailers are a different animal, abused by dunking them in water, and possibly salt water to make it worse.

About bearing (castle) nut - I seated the bearings by hand tightening the nut while turning the hub, then backed off one or two notches of the castle nut and inserted the cotter pin.

As far as the "laser" thermometers, I would not bother. If the hubs are running too hot to hold your hand on them when you stop for gas, something is very wrong. The drums are a different story they get really hot, and fast and could blister your fingers. But you don't have brakes, I just remembered.

Hey Greg..how do you really feel about "You Tube" videos?

Hmmm

I am not quite sure if I should check the videos out or not now...you are giving me mixed signals here....I am so confused now.



I did find good campground artistic campgrounds on you tube..I think they are located in LM in Washington State ..they always have art


And what is "diddly" any way???...

ALLLLRRIIIGGGHHHTTTT....

So, some interesting things happened tonight in our 1st attempt.
First, we humorously missed the step about loosening the lug nuts on the wheel prior to getting this whole thing started... so, after some how managing to wiggle the front AND rear bearings out with the wheel still on, we had to put the whole thing back together, lower the trailer (to get some pressure) loosen the lug nuts and then start over again. Good learning experience.

On a quick visual inspection, the bearings seem to be in good shape. The grease did not seem 'burnt' or discolored, or dirty. I will know more after I get the bearings cleaned off and inspected more thoroughly.

Now to the interesting part... I think I might have breaks??? I found some wires and what looks like something that is 'break-ish'... check out the pictures here. If I do indeed have breaks, I am pretty sure they are not hooked up (the dealer said there were no trailer brakes). How do I test them?

Here is a link to a folder of pictures, let me know if you are unable to access. https://goo.gl/photos/1U5Y5jr3jbrYxnAA6
