The assemblies are completely dry (no grease) so having never done this before and not wanting to cock it up please could someone give me some instructions on how and where to put the grease?
Go to the stickies, in this trailer section, and about five posts down you'll see a two-parter on how to change a set of taper roller bearings. The finishing bit (i.e. the greasing and installing) will be the bit you're interested in. All the best.
Make sure to use seawater resistant grease!
General purpose grease is lithium based: salt converts (part of ) the grease into soap, water then lifts it off and attacks the bearing balls/rollers. Marine grease - like everything else for a boat - is quite expensive, instead you can use graphite filled grease.
