Starbrite grease is good stuff, so no issue there. Whip off the wheels to take another look. The thrust washer goes on last followed by the castle nut. Tighten with a ratchet to nip it slightly, then back it off a 1/4 turn, then add the split pin. There should be only the slightest play in the wheel. Could be the wheel splatter is because you overpacked the bearing with grease.

If you're running bearing savers, it's probably a matter of too much added grease. Only need to get the outer disk to move, not get it fully jammed against the housing.

If not, then either a bit too much packed into the hub before fitting, a failed grease seal, or a corroded grease seal bearing surface.

My hubs tend to run a few degrees above ambient; my general rule of thumb (if I don't measure the temp - generally runs under a hundred degrees F) is that if it's uncomfortable (not painful, but just uncomfortable) to touch with a bare hand, it's too hot and needs to be addressed.

Thanks all for the advice. After reading comments hubs were definitely running too hot. Just finished re-fitting hubs. Have taken both hubs off - seals look fine etc, fitted back on ensuring seal is sitting correctly. Greased without over packing. Tightened castle nut while spinning hub, back off then again to ensure all seated correctly. Backed nut off and placed pin one notch back from previous position which to be honest does feel as though there is too much play in the wheel. If I put the pin back to original position wheel is not spinning completely freely. Going to test tomorrow on 30min run and see how I get on. Fingers crossed. Once again thanks all.

If it wasn't spinning freely it's too tight.
As I've said elsewhere on here for taper rollers I tighten whilst spinning wheel until they get stiff.
Then back off until I can detect play rocking the wheel with a 12 & 6 grip.
I'd rather have slightly too much play than too little. Never had an issue that way incl MOT test on cars but I did overtighten a taper roller on the Scimitar & ended up being recovered when the bearing broke up as a result.

Hi Paintman. Many thanks for your responses - have been really helpful. It seems the problem
I have is can't lock castle nut in best position. On one there is a slight amount if play in wheel but it's not spinning completely freely. Next notch back allows the wheel to spin completely freely but lots of play in wheel. Difficult to know which is the better one to go for but as over heating need to go for the looser setting. Concerned wheel may be too loose though. Will give a run tomorrow.

If you tighten with a spanner then back off one flat then probably too tight
As a guide I tighten the nut with a pair of pliers then back off to 1st available hole which is usually spot on
Using pliers means you get limited torque on the nut so you are sure your not over tightening

been following this thread with interest. these things are exactly why i bought a spare set of bearings and a wheel.

i carry them every time i tow with a tub of grease, scissor jack and spanners so i can effect a repair on the side of the road if needs be.

i've known (and seen) too many people cook a bearing and get stranded on the m1. it's good to see people take trailer maintenance seriously. it appears to be an often overlooked piece of essential tlc.

next month i trailing down to hamble point marina from york so i'm getting all my checks in now.

If loosening one by one flat on the nut produces a large movement then I'd be looking for some other problem

This is where I am struggling - I agree seems crazy considering it's only 1/6th of a turn but it makes that much difference. I'm going to give a run tonight but concerned wheel may now have too much play which may cause other issues. Getting totally ***** off with it to be honest. Seemed a simply job to do - may just take it to Indespension and get them to have a look at it.
