Default Changed out half-shaft. Got a question.

Today I changed out the driver's side half-shaft on my wife's 98 LGT. The job went flawlessly. However, I noticed something odd about my NAPA reman axle. The outer and inner "cages" are larger in diameter than the OEM axle cages. The reman shaft fit perfectly, but I found it odd that the inner/outer cages were about 1/2" larger in diameter than the OEM units as well as the whole reman axle weighing probably 1 to 1.5lbs more. Should I be concerned? The car seems to drive fine.

Did you check the part number and the correct torque that allow for the new (or remanu) part?

That year 98, I think there still some FWD subaru available, and it may give you the wrong part.

No, there aren't any FWD Subarus in the USDM after 97.

I think 90 FWD axles are compatible WAY up into the 90's...

I double checked the part numbers on the box to their site and the numbers match up.

I've seen this before. I think perhaps different manufacturers use slightly different materials when they make them and have to account for material strengths/weaknesses and engineer around them. That may not be the case here, but it's a possibility.

Also, some aftermarket companies just make beefier products. GCK axles on old ea81 and ea82 Subies have larger cups because they're much better axles, and will stand up to much more abuse.

Also, yes, front wheel drive axles had larger cups, as more torque was transmitted per axle than AWD models. However, as mentioned, Subaru brought no FWD models to the US after 1995. Older FWD axles might fit as far as length and spline count, but if Napa or anyone else lists FWD axles for a 96+ Suby, (dare I say it?) they might not know what they're talking about.

I am pretty sure that http://www.cars101.com mentions that there actually were a few (very small number) FWD Legacys sold in the US during the 1996 model year... Mostly fleet vehicles and cars sold in the south east I would imagine.


EDIT: Yes, it lists under 1996 Sedans:
L model manual trans, front wheel drive: $17,690 as the lowest cost Legacy available
but has a note mentioning that very few FWD sedans were actually sold.

While I have never personally seen a '96 or Newer FWD Subaru I have read about a few being available for sale on the internet.

Thanks for that info, Jonathan. I had heard a couple of times that 95 was the last year for FWD but I trust Joe more (and you too). FWD ftl!
