I can point you in the right direction in regards to determining the correct hub and drum for your heavy 14,250 lb trailer, but we would not have any way of identifying the exact hub for your 1995 Trailmax. So there are a number of things you'll need to know to get the right hub; first, you need to know the weight rating of your axle, and also what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them.
If you are unable to find them, you need to use digital caliper and measure your spindle to the thousandths of an inch where the bearings and grease seal ride. You can use the photo I've attached to see exactly where you need to measure. Additionally, you need to know your hub's wheel bolt pattern; if you do not know what it is I have added a help article which details how you can find it, as well as a printable bolt hole template you can use.
For example, the Dexter Trailer Hub and Drum # 8-219-4UC3 is for 5,200 lb - 7,000 lb axles, uses inner bearing 25580 (1.75" inner diameter), outer bearing 14125A (1.25" inner diameter) and a grease seal with a 2.125" inner diameter.
If you get back to me with this information I'd be happy to try and help you find the correct hub; I have also added a link below to our entire selection of hubs for you to come back to.
