trailer bearings, well it was once a caravan! need new if i wana take it a long distance, no biggy car bearings only take 15 mins.

but these ones are not taper roller bearings, they are straight ball bearings!

question is, can i update these to taper bearings? pressumably yes, if the bearing sits in the back and front of the hub?

anyone tried this before?

i really need to knock one side out and take them to the bearing shop, but if cant replace at all, im really knackered
