Hello All,We have a 37' outback travel trailer that I recently installed CRE3000 MorRyde equalizers. When I had the wheels off I noticed some uneven tire wear. The inside of the tires has worn much more than the rest, and getting pretty smooth on the inside edge. From what I have read that is typically caused by alignment issues or overloading. We have about 10k miles on the trailer and these were the stock tires so I am going to replace them with Goodyear endurance, but my question is, does it make sense to also upgrade the axles? I do not have a recent scale weight and I know that is going to be some of the replies, but I believe it may be due to how often we run with a full tank of water. We are often off grid and need to cary the full 55 gallons. Beyond that we pack food and the standard RV items. Again, I know getting an accurate weight is the correct thing to do, but I guess my point is, the way we pack I do not think is extreme and we will likely continue to pack the same way. That said, will upgrading the axels help this situation? Should I continue my search for a shop that can align trailer axels? (Called 2 trailer shops so far and neither of them do this. Not sure about the RV dealer). And, if I upgrade the axels to one step heavier, do I also need to replace the leaf springs?Thanks!

First thing I would do is crawl under with a straight edge and see if the axles are still arched up as they should be.Old Thread

Without tire, axle, trailer weight specs, every reply will be a useless guess.

Adding more info from sticker on side..GVWR 10500 LbGAWR 5080lb eachTires ST225/75R15 D Planning to upgrade to goodyear E rangeAxles Dexter 184357 5200lbNow simply eyeballing the axles from the back as it sits in my driveway, you can see the front axle clearly has the upward bend. The rear has a little of it but pretty flat. Now, my driveway is on a slope so the camper is sitting slopped toward the back a bit, not sure if that matters. However, the rear tires do indeed have a lot more inside wear. Fronts have it a little but rears are much worseSo my question is, should I upgrade to 6000lb axles and the load range E tires? I have rear 50/50 on updating springs at the same time. Some say no need and others say yes. Thoughts on that?Finally, can I replace the axle beam only or should I replace it with the 6 lugs on the end, and is TK decent or should I stick with Dexter?? $100 difference per axle as shown here https://thetrailerpartsoutlet.com/collections/6k-trailer-axles/products/6k-dexter-trailer-axle-6000-lb-beam-only Thanks again all!

I would replace the axles with 6000 lb beams. I don't like to have so little margin and the manufactures rating is probably for ideal conditions. If all of your brake parts are good, just use them and only buy the tubes. Stronger springs can cause a harsher ride, if they still have a good arch and the leaves are tight together then you may be OK. I have no experience with the TK axles. Hopefully the trailer is level while being towed and not be part of the problem.

I think it should have had 6k axles to begin with. I will research just the tubes vs replacing the entire thing with new hubs, breaks, bearings, etc. Looks like the whole assembly is an easy install but obviously more expensive.

Well... $2500 later and I am all set. Ouch!! As noted earlier, I took it to a frame, trailer, axle alignment shop. Turned out the axles were quite a bit out of alignment and required bending. Springs were shot because of the original bushings and that also means the copper bushings I installed 3 months ago were already damaged. So all new springs and bushings. I then chose to force balance the tires. Lot's of labor time involved and it got expensive. Was a tough call as I could have just kept dragging it around and replacing tires every 2-3 years but I decided to get it done right. Tracks and tows perfectly now so hopefully all of this is worth it. Shop said most trailers are out of alignment. They said you can put on brand new axles and they are likely our of alignment. Anyway, expensive but now I'm ready for our next 1000 mile trip

Went ahead and replaced the 4 tires with Maxxis 10ply. Had them mounted and re-installed them yesterday. Also have an appointment with a truck shop that can do axle alignment to have them evaluate what else needs to be done. The only other thing that worries me is when I did the CRE3000 with heavy duty shackle and wet bolt kit, the brass bushings were all very easy to put in. Prior to installing I watched videos and some needed a press to put them in. Mine all went in by hand easily. I hope that does not mean the springs are worn as well as I intend to keep them. The factory bushing were totally destroyed when I replaced them but with a 3 yr old trailer I sure hope the suspension work is limited to the axles and that the brass bushing upgrades I did are enough.

Thanks again all for your thoughts and help.
You waited too long to do the bushings. Springs are shot. The spring eyes likely took a pounding from the bolts after the plastic bushings gave way. With the bronze bushings not fitting well, they will not last long. Sorry to be the bearer of bad news.

Well that stinks! but thanks for sharing your thoughts. Doing a long weekend state park trip and then dropping the trailer at the truck shop Monday. I'll have them look at this as well. Really not happy about spending insane $ on a 2018 camper suspension, but would rather get it done right and hopefully last long.

Yes worn bushings can cause all types of tire wear....then add a axle with the wrong camber and some odd patterns really show up.
Your best option for axle R&R on your trailer is a big rig trailer repair shop. They can replace any suspension part....add a spring in the pack....make suggestions....and bend the axle stub or the axle stub back to specs or replace the whole axle assy.

You really need to get your trailer axle weights before spending money on a over loaded axle.

Ya, this is the direction for sure. Per my earlier post, I was struggling to find a shop, but I kept digging around and finally found a shop that specializes in frame and axle alignment and many other items. It's an hour from home and the process is expensive, especially if axle bending is required, so getting all of the accurate data prior is the only way to fly.

Thanks again all

Have you weighed it loaded?
If not, then you should. It likely weighs more than you think..... If you do it now... No cheating going for a good weigh...Load it heavy like for a big long trip. You need to know the truth. Then youcan decide what to do about it.

As an owner operated off a trailer shop and owning several trailers with different types of axels I can tell you that on our own fifth RV about the same weights I do an “alignment” every year.
Save your money. There is nothing wrong with your axels capacity. It is out of alignment from pot holes and tight turns.
If you are bent on doing an up grade, change the whole system out for a torflex suspension. The improvement in ride and towing is huge.
