haha mate cheers
you can stand at ease now
well, in a nutshell
chrome balls are far superior than teflon
they are made of stronger material (i have sheared a few teflon balls off now)
plus, the teflon wears through in not much time, rendering the ball scrap
so, any chrome ball is essentially better than a teflon unit
many use teflon without hassle but i have had enough of them now, a good pair of chrome is the answer
next, regards ep90 or one shot, originally land rovers used oil throughout, even oil in the wheel bearings
as it is the best lubricant. it is available is large quantities inside the casing and tends to slosh about, replenishing itself and washing out the bearings etc
one shot was designed as a bodge in the mid 90s as a getaround for leaking swivel balls
i guess land rover owners managed with it but disco and range rover owners were not happy, hence the change. the whole development of land rover axles has moved away from practicality and reliability to minimising oil leaks and allowing fitment of allow wheels.
it is a pure bodge and does not offer any better lubrication for the cvs apart from the small perhaps increase in shear strength of the molybdnum, but it is slight at best
i have now gone all the way back in time with my new build, using the best second hand chrome balls i could find (£100/pair!) with ep90 in the swivels and oil in the hubs
on the subject of which, use RTC3511 inner hub seal as it is double lip and better for off road and fit to 4mm depth
if you wish to use oil hubs simply remove half shaft seals and run oil in swivels not one shot
obviously rear axle is oil anyway
i know its a lot of information to take in so maybe let it mull over for a while
another good reason for ep90 is that as you say it is easier to drain/check/change whereas one shot is kinda in there until you need to take it apart.
removing the oil removes nasties also
anyway, nice work so far, pleased to see the time and effort going into painting, feel free to holler for advice
