going thru my stash, prepping for the yard sale
have 2 Lobro CV's in old boxes - believe one is -6, per fella i got it from long ago 914 3320 2903 - is 914-4 all ? 914 3320 2901 - is what? - any help? update - lot's of good info in responses below - so I finally unboxed 'em & counted the splines 04-02-2019 the 029 01 is a -6- CV, appears to be new - in a oldish cardboard-brown box with blue Lobro printing the 029 03 is a -4- CV, also appears to be new - in a yellow Lobro box that has seen a bit of haphazard shelf life - both wrapped in brown oil-paper in the boxes fwiw - web searching the numbers comes up with varying & sometimes incorrect fitments on various of our parts-seller sites - i find the same part-number vs fit problem with new -6- rear cyl rebuild kits (ATE) that i have had for awhile - b'ot 'em back when they were NLA, from E.A.S.Y.'s last stock - "if they say it on the internet .... it may not be true" |

.... so - is the axle -to-hub spline the same for both the -6 & -4 meaning one can use either version complete axle in a -6 ????? i ask cuz i also have 2 complete -4 axles & they would be important to have as -6 spares if they fit the -6 hub Unless there is something about a six that I don't understand, yes. The half shafts are interchangeable. I think what gets confusing is that the stub axle is not part of the half shaft and either of the CVs will bolt to either stub axle and vice versa (4 bolts + 2 roll pins). It's confusing as hell but there are two separate assemblies that need matching splines of their components, but the complete assemblies are interchangeable. Assembly 1: Half shafts (2 CV joints and an axle) The splines of both joints have to match the axle which is either 25 or 33 splines. Assembly 2: Hub (1 wheel hub and 1 stub axle) I have no idea if spline counts different between -4and -6 but obviously the stub and hub need to match. - i see AA has the -4 CV for $75 - seems like a bargain? I saw those but they are "rebuilt" with no details on what that means. To be perfectly honest, I've had horrible experience buying used parts from them. 74 parts cat. This confirms they've gotten their parts numbers mixed up. If you plug the -6 axle number into the Porsche parts lookup, you get this: But it appears what you get is the old 914 332 009 01 part so the replacement note is backwards. Not a big deal when buying a complete axle assembly, but a big problem when just replacing joints. |
