Hi silly question maybe but I bought a set of 4 discs and pads and they came with 4 hub seals. So, before dismantling and getting it wrong, would the seals in the kit be the inner or outer ones? LR inner ones FTC4785 @ 6.54 ea) cost less than the outers (FRC8222 32.02 ea) so my money would be on the inners. Am I right? Can the outers be removed to clean and inspect the bearings and replaced?
