Re: Birfields or Hubs - popping noise

OK so I'm finally getting around to fixing this thing....just keep going hunting and camping every weekend instead of working on the truck.  Unfortunately, I'm restricted to 2WD roads with my current F'ed up front end.  So, I'm now pretty certain the birfield is busted.  My plan is to fix the axle and then figure out what's going on with the gear ratios (before running 4WD on the fixed axle)....first things first right.

So, what's the deal with the 27 vs 30 spline?  Are these spine counts only referring to the inner/outer axle connection.....I don't understand how you could use different spline count on stock hubs and differential.

I figured I would just order one 27 spline Marfield, reuse the inner the axle, and leave the other side alone.  Is this what you guys would suggest for me?  I have 3" lift but run stock wheels/tires.  I figured I would go with Marfields over Longfields just because I like Marlin stuff (no real justification) and planned on getting one of those ecoseals with the order (and the clip).  There is also crap available on EBay, but by the time I pay for shipping I and dealing with some yahoo I may as well go with old faithful MC parts, right?  Other option is salvage yard, but there aren't a lot of trucks left around here in Oakland, as least from what I've seen (only been here a little over a year now).
