He highly recommended going with the five spring set. In his opinion, the 3500 springs used by Dexter are inadequate for our trailers. That's good enough for me. I had asked about their 4 spring set as by yesterday (Friday) morning (the morning after Mountainman198) had posted the vendor source note, they had already sold out of the last 3 remaining stock of 5 spring sets to other Oliver owners. I was the first call Friday morning and he advised they were producing more next week (11-15 March) but wouldn't ship until NLT than Friday the 15th. Well we're departing on the 22nd of March for a six week trip and that schedule was almost a guarantee that at best, I might receive the shipped springs in time for the trip but wouldn't have time to install them. I of course would order them and have them with me just in case. So I locked in my order at 0700 yesterday morning. When I talked to Mike later yesterday he said based on my somewhat immediate need, he discussed with his production folks and they said they could have a set produced for me by next Wednesday (vice Friday) and they would be shipped that day. That's GREAT customer service. He also mentioned to me to me that in the time between having talked to him in the morning (0700), and when I called back at around 2PM, he had sold five more sets to Oliver trailer owners. He said "You Oliver trailer owners are a really tight knit group". He actually was so impressed, he went on line and investigated Oliver Travel Trailers. I have my RV mechanic on standby to replace my springs once they are received... Paul & Donna (2 HOBOS) hull 414 (last trailer produced in 2018) I thought there would be a run on these as soon as ALCAN contact info was posted! Great to hear they are going to rush one for you. Smart to have your mechanic scheduled too! I'll get a set at some point. I'm fully convinced on the 5-leaf 2000 LB rating now. If mine looked like they were starting to sag, I would have ordered yesterday too. But considering after tax and shipping these would be, what about a $900 outlay? I need to do this later since we can. We're not heading to Alaska anytime soon! To do this right, it may make sense to buy 5200 LB axles, with the best hub/bearing/brake set possible and mount new axles on these springs, given our hull is now 8 years old. Likely be close to $2K total on this idea. Should not have spent $200 on new Timken bearings just 6 months ago, if I knew then what I know now!

Yes, I came to that same conclusion earlier as well. Combine that with being overloaded would make the failures far more commonplace.

Geronimo John Posted March 9 Share Posted March 9 (edited) On 3/9/2024 at 12:50 PM, Geronimo John said: each of our tires will be supporting 1,350 pounds One needs to ask, why would a spring set rated for 2,000 pounds fail with just a 1,350 pound load? In light of the heat treatment photo, this clearly is a defective product and we have almost a dozen instances where the Dexter provided axles have failed. This is a life safety issue that OTT would be in the best position to pursue with their supplier. Not to mention, as I suggested above, OTT should be warning their customers of this known issue. Keep in mind that not all OTT owners read every thread. We all would feel terrible if one of our beloved trailers went off a cliff and took out a family due to this defect. MODERATORS: I am asking that you: Make OTT aware of this issue and the frequency for which it appears to have occurred. Strongly suggest that they provide all owners with a Safety Bulletin. And to specially ask owners that have had failed springs to notify them for documentation and further actions with their supplier. Once they have the facts from owners with defective axles, to formally advise Dexter of this issue.

mountainoliver Posted March 9 Share Posted March 9 I noticed in the photos of the new springs that they have the center bolt installed in the opposite direction as the original springs have. I think that the round bolt head should be at the top side of the spring so that it can fit into the locating hole in the spring perch that’s welded to the axle. The hex nut will not fit in the location hole. It’s not a big deal, you can turn the bolt around but you’ll need two strong C clamps to hold the springs together before you try to loosen the bolt. I’ve done this before while restoring old cars and rebuilding the springs. Probably the manufacturer should be notified when an order is placed to install the bolt for the axle mounted on top of the springs not under the springs. I’m guessing that they are used to axles being mounted under the springs on jeeps etc. for more ground clearance. 3 2017 Elite II, Hull #208 2019 Chevy HD 2500 Duramax Link to comment Share on other sites More sharing options...

The chart shows a minimum recommended load of 1585 pounds. So basically it appears that we are not on the chart.... GJ In the fine print, they always state to run at the minimum when under the min, and of course do not exceed the maximum. Given you actually keep your Oliver at 6000 LBS, you can run 35 PSI. I would not suggest subtracting tongue weight, since when running at highway speeds the hitch is bouncing up and down and half the time ALL weight is on the trailer wheels. This is why for years, yes YEARS @John E Davies ran his Oliver at 42 PSI, and suggested we all do the same. I've been at 46 PSI last two outings. Those of you still running 50, 60, even 80 PSI, STOP doing that. According to Michelin, 40 PSI is a good number for the Elite II, and when we leave to Casa Grande next week, I'm going with exactly 42 PSI to honor our good friend John E. I wonder if there is some correlation between spring failure and those running the 80 PSI printed on the tire? Or, have these springs failed mainly on those pushing the GTRW? Perhaps, but again the broken cross-section looked like cr@p and some of these leaf springs were not hardened properly. When not hardened properly, steel will bend. These springs should not bend as in the picture above. They should break if over-stressed (over the GTWR), but not bend.

jd1923 Posted March 10 Share Posted March 10 3 hours ago, Geronimo John said: One needs to ask, why would a spring set rated for 2,000 pounds fail with just a 1,350 pound load? OEM springs only need to be rated at 1750 LBS (7000/4). Most lightweight dual-axle trailers (i.e. not HD non-commercial) are rated for 7000 LBS. I have a 12 FT flatbed trailer on our property. We haul dirt bikes & quads or our side-by-side, used to pull it with our Class-C). It has the same Dexter axles (and the leaf springs still look good too, tG). Leaf springs at 2000 LBS are 14% stiffer. This is a very good number! They appear to be correct in their 5-leaf design. I will buy a set next fallor next year. Thank you.
