Replacing Dexter 2K Trailer Axle with 70" Hub Length and 58-1/2" Spring Seat Length


I have a 5 X 8 utility trailer from Carry on. The axle is a Dexter 2K7058 which means the length is 70 and mounts 58. Mine is bent after purchasing 2 AKlHUB-545-2-LFEZ-1K trailer idler hub assemblies. The bearings were L44643. these were too small. I purchased a new set of L44649, which were the old ones I miss read the first time I looked from TSC. Everything seemed to work but the axle was bent, the tire rubbed against the spring bolt. I measured the axle and is is 70 hub to hub but the spring bracket is closer to 58.5 instead of 58 as it is supposed to be. This new axle is 72 long and dont see any at 70. Will this longer axle still work with the parts listed? And is the 58 discrepancy going to be a problem?

The Dexter 2,000 Pound Axle # T20BTR-7258 that you referenced is the closest standard axle beam option we have available to the specs you listed for your existing/old unit and it should work well as a replacement. The slightly longer 72" hub face length is just going to push the hubs a bit further out (1" on each side), which won't affect anything with regards to function but just something you should be aware of. It would also allow you to get wider tires down the road if you ever wanted to.

The 1/2" difference on the spring seat measurement is the dimension that has the potential to affect fit, depending on your exact setup. Most likely just a 1/4" on each side won't matter, but if it's not lining up correctly with the frame these can always be moved by cutting them off and welding some new seats # TRSS175 58-1/2" apart on the axle for an exact match.

I have attached a short video review on this axle that you can check out as well.
