Redline shockproof seems to give good results as does the Millers EP140.
When I carried out a survey of bevel box noise and possible solutions Redline Shockproof only worked in a few cases.
EP140 is now recommended by MMC but again has mixed results. My first fill with Castrol EP140 quietened the BB down a bit but after the 2nd fill it is as bad as ever.
