new Bearings

i have recently degreased and repacked the bearing but they are very slightly noisy although no visible wear and no play.I am sure they will be okay for towing but just to be safe we are getting the bearings replaced.Vicki has a business contact who will supply and replace all the bearings and races properly using a press so hopefully soon we will have silence .
The best bit is the cost £0 all in

are they easy to get to??

Not really a DIY change but they are easy to get off if you have access to a press etc. like Nick said...

Bearings races can be fitted with a light tap & a brass punch but its not best practice
