Hello all!

I searched but couldn't find anything, maybe I'm a searchnoob lol...

My question is, apart from the differential and driveaxles, is the rest of the rear driveline identical in S4s and S5s and verts?

I'm particularly interested in the arms/hubs. I've found some replacements but I don't know what FC they're from .

I got an S5 and I want to change my rear right hub cause its end-axle is slightly bent (vibrations and brake noise yo) probably from a crash or something.

Thanx a lot for your time!!!

Bump!

 

The only difference would be a 4 lug hub from 5 lug. But both have the same spline for the axle. As long as you get the same lug style, they will be identical.

 

Thank you very very much jjcobm!
When you're about to spend some money, you 've got to be 100% sure that you won't buy something that will not fit...
Help much appreciated!

 

Well I just learnt the hard way that the 5-lug hubs are not identical. There are 2 versions, one with the ABS rotor and one without it. The replacement of this rotor is not worth the effort cause you will need new bearings and the costs exceed the price of a new hub from Mazda.

This just to know and be aware of when hunting for a hub.

 

How is the replacement of a brake rotor going to require the removal and installation of new wheel bearings???? Those are two completely different things. And regardless of that, both ABS and NON-ABS brake rotors will fit the hub. The ABS sensor reads the gear behind the lug nut studs on both the front and the rear hub assemblies.

Unless you are trying to pull out the part that holds the lug nut studs on both front and rear of a 5 lug car (why on earth would you do that???), then both front and rear 5 lug ABS or NON ABS hubs will work just fine.

Also, if you are talking about replacing the ABS sensor gear (why would you need to?), or if your car has ABS and you are trying to fit non-abs hubs then you can just eliminate your abs system. You are one of the few "lucky" owners with ABS on their 7 if this is the case...

Mazdatrix sells an ABS delete kit if your car has it. Otherwise get the ABS (or non) hub assemblies and bolt them up... http://mazdatrix.com/j-3brake.htm

 

Hey dude thanx for the response...

I bought a used flange/hub assembly and realized that it came from a car without an ABS control unit, so it lacked the ABS rotor, not the brake rotor!

My car has the ABS function (and don't want to delete it, cause it can be deactivated at any time via the key position), so the used flange/hub I bought has to be fitted with the ABS rotor. To do so, you need to disassemble it cause it should be mounted on the stud lug via 3 screws from the rear. Therefore the bearing will get damaged while coming out and a new one will be needed to be pressed in.

What I noticed though is that you were right, the hubs, flanges, seal and bearing are identical. It's just the ABS rotor that is missing and causes the trouble to replace. Oh well, a price I can live with...

Thanx mate!
