I've recently purchased a used trailer and one of the hubs needs some work.
Two of the studs are sheared and the other two just spin in their holes.
Can the studs just be knocked out and replaced with new or will I need to drill new holes as they are spinning so I assume the new ones won't be a tight fit?
Or am I better of just buying a new hub? It's an indespension so looking at 100ish for a new hub which I'd like to avoid on top of the other brake items needed.
Personally for the cost vs hassle (of loosing a wheel) I would fit new hubs. On unbraked trailers I have replaced the stubs after threads were stripped. That wa a get it home on a borrow trailer situation local indespension place is pretty good and competitive considering shipping so I would take hub into one and see how it looks compared to a new one replacement studs are £10
Studs usually knock in from the back the snapped ones should just drift through the studs are stopped from spinning by splines which are formed on the shank of the stud which cut into the hub as they are hammered in. Often when a stud has turned the hole is worn slightly so a new studd will be a slack fit. You may get away with a new stud and some high strength locktite or occasionally a tack of weld on the inside to stop the stud spinning. Plenty of grease on the studs when you refit the wheel will help prevent them turning again.
Plenty of studs available on ebay for £5-£10 per set just order the correct size you need
