Front Rotor/Bearing Replacement Options

[seanery]

Quick questions...how much grease? What kind? What do I torqe bearing retainer to?

thanks!
getting a bit dirty! woohoo! (am I motivated? I'm trying (IMG:style_emoticons/default/smile.gif) )

I don't agree with seating the races "on the fly". Races should be seated firmly "before" you begin the bolt it back together phase.

I agree.

If you have to keep tightening and tightening to seat races and you're using your bearings to do this I'd think things aren't going well...

I don't quite agree. First, not everyone has access to a press. However, any sufficiently strong screw (like the spindle and the retaining nut) works very well as a nice, gentle press. Seating them as well as you can with hand tools, enough to get the seals installed, then finishing the last bit with the retaining nut, seems to be a perfectly sensible procedure. I hardly invented the idea. It's taken right out of the shop manual for most Alfa Romeos, which have a nearly identical front hub design as the 914. Indeed, the Alfa manuals even specify a torque value for the "seating" phase, then another torque value for the second phase (33 v 7 ft/lbs, if I remember correctly). Repeating the process later also ensures that after everything's gone through a few heat cycles ensures things are fully seated, and there's no need to remove everything, just take off the dust cap and go through the two tightening cycles again.

It may not be necessary, but I don't see where it hurts, and I can see where it *could* help.

And seanery, yes, you should have frozen at least the races first. I've never had to heat the hub (no really access to something to do this properly w/o endangering my marriage), but freezing the races helps a lot.

I don't grease the hub, and certainly don't want any between the race and the hub. This is supposed to be an interference fit, so there's shouldn't be any clearance for even a small amount of grease in between the race and the hub. The very last thing you want is to invite even the possibility of the race spinning wrt to the hub. The spindle should never touch the hub itself, and should rest entirely on the bearings, which also should not spin wrt the spindle, so you don't want that greased, either. Perhaps I'm misunderstanding what's being said here...
