so i thought that the reason a regular 9-3 suspension (ie knuckle/whatever you wanna call what the shock sits in) was due to a viggen using larger splined axles. i may be way off base.

would swapping the hub solve the fitment issue?

im very confused since eeuro lists a hub as fitting both regular 903's and some viggens, but not a 99...

thesaabsite lists a different set of part numbers for regular 9-3 knuckles vs viggen knuckles

http://www.thesaabsite.com/93/93frontsuspension98-2003.htm

on the other hand, they list the same part # for ng900 hubs, and for 9-3 hubs, which are different depending on what year...

so i have no idea
yes thats part of why i was not coming to any conclusion myself.

i though the difference in brake setups was just the caliper carrier, i didnt realize the spacing on the actual knuckle was different. i guess that throws the idea out the window then.

my understanding is that viggen/95's share the same nuckles/axles which is why 93 stuff wont work

wait I have viggen brakes on my 97 ng900 and all it was was a different carrier and rotor... very easy swap...
Yep Me too.
But the Viggen does have larger Drive Axles.
The actual Hub is larger to accept the larger drive axles. Therefore the Knuckle is bigger However the spacing of the caliper bracket mounting holes are the same.

Normal 9-3 knuckles wont work on a Viggen unless you changed the trans and used the standard size drive axles.

Not sure why you would want to do that.

i wouldnt.

i just thought there might be a possibility that the inner diameter changed on the hub, meaning there was a chance i could just put vig hubs in the 9-3 knuckles.

i was after something to make a suspension job easier.

The Viggen (SVO written on them) have the space where the ABS ring is counterbored to clear the larger 9-5 outer CV. This larger sensor ring also means there is a viggen specific bracket for the ABS sensor. If you try and use the base knuckles and tighten the hub nut it will make a mess.

Hub, bearing etc are the same. A local machine shop could spot face that area for not a lot of money. It is pretty simple operation. Just a bit unwieldy parts.

It is what I did when mounting the F40 gearbox: the driveshafts matching the F40 are those of 9-5/Viggen (F35), so I had to trim the inner face of the hub to make room for the bigger driveshafts.
Also, I had to put some washers/spacers between the ABS sensors and their brackets, to have them retreated in an outer position.
Not such a big engineering thing, just a lot of work to take everything off the hub, to prepare the zone for the "intervention".
In the future, I might simply source a pair of Viggen hubs ;)
