Kwhistle Posted August 30, 2011 Share Posted August 30, 2011 I posted a couple threads about the tone wheel troubles I've been having... I tried repairing it, and it seems like it's holding, but the ABS isn't working. Here are some pictures of what I done: Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.us Basically, bolted the broken pieces together with a metal plate and ground the nuts on the other side to the same shape as the original teeth with a Dremel. Still no luck, so would appreciate any ideas. I really would rather not have to pull the hub to replace this, as I understand it's a major hussle. Could it be that the heads of the bolts are touching the inner part of the rotor and offsetting whatever magnetic field is measured by the sensor? Would grinding these down a bit fix this, or is this completely hopeless? Link to comment Share on other sites More sharing options...
idosubaru Posted August 30, 2011 Share Posted August 30, 2011 are you positive that's the trouble? might want to flash the codes and make sure the sensor itself isn't hosed - did it get tweaked or hit when the tone ring failed? if it's not working out, a used hub might be the way to go, you can swap those out rather quick.

I'm pretty sure it's the tone wheel, not sensor. I did flash the codes, and breaks were grinding and pulsing for a minute, and then ABS light came on. So pretty sure it's the tone wheel.

nipper Posted August 31, 2011 Share Posted August 31, 2011 Did you repair a tonewheel? You cant repair them they need to be replaced. Sensors need to be perfectly cylindrical in shape, even the slightest erosion of the edge will cause them issues, Link to comment Share on other sites More sharing options...
eulogious Posted August 31, 2011 Share Posted August 31, 2011 I'm pretty sure it's the tone wheel, not sensor. I did flash the codes, and breaks were grinding and pulsing for a minute, and then ABS light came on. So pretty sure it's the tone wheel. What code did you get? You haven't mentioned that yet. The abs unit will tell you what's wrong if you do the code dance with it… Not knowing the code makes it hard to say what's really going on. Most of the sensors like that need to be precise as nipper said. Trying to patch the tone wheel back together won't really work unless you use a mill to mill the parts to spec. Even then it's a crapshoot that it will work. Either buy a new tone ring and go through the hassle of replacing it, or just grab a used hub and slap it on. If it were me, I would check the code to make sure it's the tone ring before doing anything else and wasting my time on something that might not be the issue.

TONYB Posted October 28, 2011 Share Posted October 28, 2011 I have just smashed my front right tone wheel, does any body know the part Number and cost, mines a 97 Outback Link to comment Share on other sites More sharing options...
Caboobaroo Posted October 28, 2011 Share Posted October 28, 2011 I don't think the dealer sells it separately but I could be wrong. You could always go to the junkyard and get a knuckle with the tone ring, have the hub pressed out, swap the tone ring onto yours and press the hub into a new bearing. As far as the repair, you'll never be able to fix the ring itself and have the ABS light stay off. You'll need a new ABS tone ring. Link to comment Share on other sites More sharing options...
Kwhistle Posted October 29, 2011 Author Share Posted October 29, 2011 I have just smashed my front right tone wheel, does any body know the part Number and cost, mines a 97 Outback This web site sells it: http://www.partswebsite.com/subarugenuineparts/index.php?type=parts&start=1&tabdes=1 I looked at it back when mine broke. It was expensive. I fixed mine as I described here: http://www.ultimatesubaru.org/forum/showthread.php?t=127205 Local pull-a-part didn't even charge me for it, they didn't know what it was, and I broke it in half anyway so that I don't have to disassemble the hub. The fix I tried in the pictures above didn't work, I suspect because the heads of the bolts were pressing against the rotor, which caused "fixed" section of the wheel to protrude out and broke the ABS sensor. I got a new sensor from the same pull-a-part for about $10, if I remember correctly. Link to comment Share on other sites More sharing options...
