You have a shorter stub spindle on your axle which we do not have a replacement hub that will fit. The only solution we can point you towards for your trailer is a new spindle that is longer like the BT8 spindle part # TRU94FR which would then allow you to install a similar hub that you referenced part # AKIHUB-545-2-1K which has the same 5 on 4-1/2 inch bolt pattern.
Spindles need to be installed perfectly square so best option is to find a shop local to you who has experience with this... view full answer...
