Other than the ear mark for the sensor, and the lack of abs hardware, is there any other difference between an abs spindle and non abs? I took a look at Mazdatrix and it seems the bearings and hubs are all the same part. So I'd assume, theoretically, if I needed to, I could disconnect the abs on the passenger side and use a non abs spindle on the driver?

Correct, ABS and NON ABS are the same except for the little cast bracket and tapped hole. Hubs are interchangeable.

I'd say they are interchangable as the S4/S5 have the same number only the S5 Turbo different. Just like the rear toe control hub/spindle. They are all the same S4/S5 ABS or no ABS.

Thanks for the info guys.

What would be different about the S5 Turbo? When I looked on Mazdatrix, 86-92 all had the same parts for the hubs, bearings, seals, etc. So I'd assume a S4 Base Spindle would work with an S5 TII ( minus the abs ).

Just trying to figure out my options. I got a non abs spindle and need to know if I can make that work on my S5 Turbo until I can get a abs spindle.

I figured it out. Took a look at the FAQ last night ( and forgot to reply to this thread ), but only the S5 Turbo came with ABS.

Yes, I thought of that, but you could also get ABS in the S4.
Maybe the Mitchell manual didn't take that into consideration on teh S4 as it was optional.

I bought a s4 GXL once that had ABS, only FC I've ever seen with it. haha

So it was definitely an option in the s4.

Yup, Option S4 GXL and Turbo
Std S5 Turbo, optional on other models not offered

I swapped all my ABS hubs on my S5 turbo with non abs hubs from various cars. They will all work.

Hrm, I missed the part about abs being an option for S4's. Alright, back to the 2nd gen parts section. Thanks guys.

If you find a deal on an ABS spindle to replace one a non-ABS spindle, you probably shouldnt bother. Your brake caliper will NOT bolt up. I just tried to do this, and now I'm left either needing to grind off the ABS part of the spindle, or find a new NON ABS spindle...

For those with ADD.... You CANNOT swap an ABS spindle onto a NON ABS car without GRINDING THE EXTRA METAL OFF.

although I hear that if you're not single piston calipered, it works fine. I'm running single piston.
