Trailer Bearing protection

[Heno]

as mentioned above the hub can be presureised when useing bearing buddies and the inner bearing is usually running dry of grease(if the pressure doesn't blow the seal first). You can buy seals that have a pin hole to relieve the pressure but this means if you forget to regrease the bearings then water will enter the hub and then your up for new bearings. Either way regular checks will prevent any problems. A regular visual inspection is a must but this is just my opinion.
Cheers,
Heno.

do the bearing "kits" from places like bias or whitworths have the best seals in them? how do i identify the chevron 2 piece seal mentioned in this thread?
