Then I guess that's the 3 or 4 inches you mentioned earlier, Mike. Wow, that's 19" or more per side of overhang (to the hub face / wheel centre plane)! Maybe the Tie Down axles are designed for this (to suit wide boats on narrow frames), but it's still a lot and any extra is not good.

I would ask the trailer manufacturer why the axle is so wide, and unless there was a good reason from the manufacturer I would plan a narrower replacement... as Mike had already determined at the beginning of this discussion.

Jeremy Hudson at Wesco sent me a schematic of the #50064 axle supplied with my Hauley.

Ok, I believe the body is 6.5' wide, right? 78"?

Well, the axle has a 82.48" tube. And the distance from hub face to hub face is 94".

So I guess the reason the wheels stick out so far is because of the spindle/hub assemblies are long. Clearance between the arm and the trailer body appears to be 2" at most, assuming a 78" wide trailer body.

I guess there's no getting any narrower with that axle design. Clearance is only about 2" on each side. Yet, assuming a tire width of roughly 7.5", half on either side of the hub, 90" minus 78" equals a sizable gap from the tire's sidewall to the trailer wall.

I guess I can't really say I had no warning about the axle width, since Snoozy's website says in the specs that the total trailer width is 7'11". Now I realize what it's like to tow an 8' trailer. On narrow country roads it's a pain. On the expressway, not so bad.

It gives me new appreciation for those 6'8" wide Scamps and Casitas.

Here's another way to look at those numbers...

The axle tube is 82.48" wide, which is wider than even the widest part of the body. The frame is substantially narrower than the narrowest part of the body, so the axle cantilevers out substantially past the frame - the issue we were discussing earlier.

If the body is 78" wide at the widest point, it is likely to be at least a couple inches narrower than that near the bottom, even before it turns the rounded corner to become the floor. The arms are roughly level and pivot on the middle of the tube which is under the frame, and the frame is under the body, so the arms are more under the body than beside it. My guess is that there's lots of clearance from the arms to the body.

The vertical-sided fenders are forced apart by the body width high on the side, which in the worst case would place them 78" apart. With a hub face spacing of 94", that places each hub face 8" outboard of the inner side of the fender... but the fender doesn't need to be much more than 8" wide in total to cover the tires used, so either the fender is much wider than it needs to be, or it is far from snug to the body, or some combination of those. It looks like the fenders, and hub faces, could be 3" further inboard on each side. (Hmm... where have we heard that before?)

Taking all that in combination, it sounds like the same design with six inch narrower axle (all the difference in the tube, so about 76.5" tube and 88" hub face spacing), and the fender supports shorter to match, would allow everything to clear and make the trailer both more robust and more usable.

Perhaps the axle was sized for a 78" wide trailer with straight vertical walls, and 2" clearance from arms to body? It could even be a standard stock axle for 7' wide trailers. The narrower axle on Carl's trailer seems to confirm that the #50064 axle was too wide.

That's a good point: the specs say 7'11" (the 6'5" body plus outboard wheels and fenders), but with 94" across the hub face and 8" of tire, Mike's trailer must right up to the legal limit of 102" (8'6"). It is wider than it is supposed to be... again by 3" per side.

trailer width

I believe all federal highways are 102 in (8 1/2 FT) wide trailer size . NC is known to measure boat trailers and give out tickets for more then 102 in. I looked at a snoozy the other day it didn't seem over 8ft ?

My figuring must have been off. I take back what I said yesterday.

I went to the trailer place and took photos of the wheel area.

The above photos show a new tire. The worn one that called my attention to the problem last Friday can be seen below.

It appears to me that the crown nut at the back of the hub is 3.5" away from the trailer sidewall. If they had made it 1", they could have narrowed the overall width by 5" (2.5" per side). Also, the arm has an upward angle; if they had used a down angle, they could have gained even more.

The trailer shop was having little success finding a narrower drop axle (for springs), but they had a narrower straight axle on hand. So I told them to put that on. It will raise the trailer about 4", they say. No big deal to me. I guess I won't scrape the bumper any more.

Right, a Snoozy is not supposed to be over 8 feet wide, but Mike's seems to be about 6" wider than it should be, and thus up to that legal limit.

Right, by having 2.5" per side less of that square axle tube that is clearly visible in the photos.

This would result in 89" track/hubface distance, and 96.5" width across the tire sidewalls... still not counting fender lips and yet still 1.5" wider than spec, but much closer.

So, with the narrower axle the wheels and tires will be where they should be. Is the shop going to remove the fenders, cut the fender supports shorter to match, and replace the fenders to line up with the new tire position? I assume this is about a 88" hubface width.

Not surprising, but will the fenders be relocated down to match, or are they just going to be way above the tires? I would at least extend the fenders with mudflaps to protect the body from thrown gravel.


Just to complicate things...
One reason the Snoozy has external wheels was to allow the axle position to be adjusted in the design. Any axle replacement is an opportunity to tweak the tongue weight by shifting the axle slightly forward or aft, although the fenders would need to move with it for anything but very small changes.

trailer axcels

Maybe because you have a lil hauly instead of a lil snoozy your axcel is for more weight ? I would have asked Allan to confirm . The snoozy I saw the wheels were very close to the fiberglass body not like your pictures? Good Luck with your project .Jim

Id love to see those same pictures with the fist on a regular LiL Snoozy as a comparison.

The shop is locating the new axle so the wheels stay in the same position as now, under the fenders. I believe he said it would be about 6" behind where the axle currently attaches, and most likely they will be able to leave the current attachment plates intact (so a reversal would be easy should the occasion ever arise).

This will contribute a small amount of additional tongue weight. I weighed the tongue fully loaded in the latter part of August, and it was 330 lbs. So that may go up to 350 or 360, perhaps? When empty, the trailer produces an annoying little front-to-back jiggle at 40-50 mph, so this might kill the jiggle.

I will worry about the fenders later; I just want my trailer back!

I guess Snoozy started out with a wider axle, thus the 7'11" notation in the specs. They must have gotten Wesco to switch to a narrower axle at some point. But for some reason, I ended up with a wider one. Sure wish I hadn't. Maybe I would not have hit that rock.
