Hi all , i will try and keep this brief no one wants to read a novel , So it started with a mild vibration during the year it got progressively worse then a grinding feeling in the brake pedal ,seat back etc got a nasty queeky noise were the drive shaft arrives at the engine , me thinks uni joint so 4 days ago broke it all down the uni joint had nasty grinding marks almost to the needle bearing cups , yippee found it replaced said joint lots of moly paste the job went ell , short ride about 1 mile all seemed fine so yesterday did a 150 mile round trip omg the grinding feeling came back with the most awful squealy sort of noise off throttle {ie off gas} me thinks dive shaft flops around to much so take it all down again well the shaft does flop about but the splines look fine on both ends , removed drain bolt on the magnet no metal fillings so before i put it all back together ,PLEASE HELP , were do i look now , as an aside comment i have asked 2 { goldwing expert shops here to actualy do the work and they all declined i think i can see why]

Reads to me like it must be somewhere that the moly was applied. Was it the proper moly ? I ask cause it will make a difference.
As you understand I'm sure without seeing it's hard to guess but look through everything else too. If the shaft is sloppy in the joint, shaft has to go, imo.

update thanks for the reply here in the uk its called MOLYKOTE HSC plus paste made in Germany by the DOW-CORNING CO used gob loads then before i put the bike completely together went for 1 mile ride it felt 90% better but the roads here are so bad, rough as a bear or badgers butt , when the rain stops i will try it again ,

second update the molykote is not good as it has no lithium grease carrier lasted about 80miles , so i now have some moly 77 from a company in Darlington [England} they make it to Honda spec so i will try this , am collecting a new oil seal for the prop shaft tomorrow the shop tell me the goldwing expert will be there so i will take the shaft with me and ask if its worn because i cant see any wear but as i have never seen one new how would i know , any way more news to follow , PT
