Interesting tidbit on front brakes for pre 3/99 and post 3/99...

The dividing date for the front brakes on the '99 was due to adding 4 wheel ABS (vs rear only on pre-3/99).

I needed a front wheel bearing assembly, so I ordered a a Timken 515020 by accident (it has the abs sensor). As it turns out, it's .20" thicker (mounts the wheel out further by .2"), made this way to accommodate the abs sensor. The pre March of '99 require a different bearing assembly and disk brake rotor.

The catch?.... the correct parts have limited availability iin the aftermarket, and cost about 2x the cost of the post March/99 parts...

I needed front brakes and ended up replacing both bearing assemblies on my pre-3/99 with the post-3/99 bearings (only cost a little more than a single non abs bearing)...allowing me to use the EBC slotted rotors. The calipers/pads etc are all the same.

Motorcraft rotors are made in china for my pre-3/99. Not happening. Now I can buy the post-3/99 much more cost effective parts. Hopefully this will help someone...(they also have course/fine thread lug nut options for the bearing assembly)

Good to know. I had to do all my rotors a few years back and that's when I found out my engine is late-99 but my chassis is early-99. Makes things fun, don't it?

So you're saying to "convert" you need both the unit bearings & rotors, yes? Any other parts for everything to mount up, etc.?

Correct. everything else is interchangeable. There is no performance advantage to this, just lower parts cost and availability (the rotors are the same diameter and thickness, it's just the 'hat' dimension of the rotors that's different).

yep...mine were not all that much more though.
but if your rotors are warped and your bearings questionable i would get the 99.5 kits
there is even an ebay guy that sells the kit.

but i would prob get powerslot or similar rotors..

pads are the same and the wearable part so i did not care much...
i wish ssb calipers were cheaper

The flange thickness was changed to stiffen it and decrease runout.

An SP580205 hub is the same as a 515020 except it has fine thread studs and cost less.

If only those who knew what they were talking about replied, this thread would still be on page one.

The flange where the bearing mounts to the steering knuckle or the flange where the wheel mounts to the hub?

My 515020 (Timken) wheel mounting flange was the same as the factory part that I removed, didn't check the other stuff - but did snap a couple of pictures...

I was under the gun to get this stuff done, and found this out by accident when I ordered the wrong parts...need to remind myself to check the forums more! Knowing this ahead of time would have saved some headaches!

As far as the pricing goes, I was under the gun - ordered through Amazon (we use Prime and can get the stuff in 1 day, and they seem to have very good pricing on the timken's). Ordered ball joints last night, with one day shipping - tracking numbers show it leaving the warehouse in KY this AM with a scheduled delivery on Cape Cod this afternoon (under 24 hours since ordering them).

My unit bearing on my e99 went out one Sat night and I got a L99 one, all anyone had. Put it on and just used a washer on each of the two caliper mounting bolts to space the caliper out that .2" No biggie.
