[s-cars] ur-S4 front and rear hubs the same?

[Ian Duff]

The US FA (rev 6.1, update 525) lists the same part number for front and
rear for model years 1992-1997 for AAN-engined cars (100Q for '92-'94, A6/S6
for '95-'97). Part number is the same as Bob lists for the You're-a-pee'in
ones, 441 501 653 B. One part number front and rear, all years the S4/6 came
to the US.

The US FA lists the part number you quote (441 407 615 C) as the hub for '91
200 Q with 3B engine, and list the '92-'97 S4/S6 hub as an alternate for the
same '91 200 Q with 3B, except with the note "(for modified vehicles)". This
leads me to believe that the number you quote is the hub for UFO cars, and
if you have a G60 equipped car, the hub remains the same thru the '97 AAN
S6.

HTH.

The rear hubs are listed in Illustration 501-10 of the FA.  The fronts are
441 407 615 C for the '92 & '93 S4 only, but I believe that is for European
models that had the UFO front brakes.  Starting with the '94 model year the
front hub was changed to be the same as the rear hub.  This was coincident
with the deletion of the UFO brakes on Euro models.  The part number for the
rears is 441 501 653 B.  So, I'm assuming that for US cars, the '92 & '93
cars had the same hubs front and rear (441 501 653 B).  This is definitely
the case for '94-'97 cars.  However, I don't have a US version of the FA
loaded to verify it.
