Hello Lee,
Yes, you can replace your old 2-piece hub assembly with the Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter - 5 on 4-1/2 - Pre-Greased (#AKHD-545-35-K), as long as your current hub uses an inner bearing L68149 (1.378" inner diameter) and an outer bearing L44649 (1.063" inner diameter). If you do not have a 3,500 pound axle please let me know what your axle capacity is so I can find the right part for you.
If you prefer not to clean your bearings to check the numbers, you can measure the spindle instead (refer to the attached image) to ensure the dimensions match.
