Are you talking about the ABS sensor? I would recommend Timken bearings. They aren't very expensive and I've heard very good stuff about them. I just replaced my rear hubs and got a pair of them from the local autozone for about $210. Stay away from the cheap chinese crap.
The sensor is located in the knuckle, one 10mm bolt if I remember correctly. The tone ring is on the axle on the inside of the knuckle.
The hub is separate, you'll need a T55 torx for the three bolts. A little crowed up in there but take your time and you'll be fine.
FYI, you get what you pay for when it comes to rear hubs for the most part. Don't expect the cheapies to last like the OEM one did. I have a Wheel Bearings Inc. one on the left side of my car for one season. 25 drag strip passes and 4 auto-x's and it is still tight. We'll see how it does,they are about 120 at Summit Racing.
The rear ABS sensors are not in the bearing/hub assembly.
All C4 rear hubs are identical; regardless whether ABS equipped or not.
The speed sensor for the ABS is the toothed ring shown next to where uni joint connects
please let me know if 91 is equipped with sensor in rear hub ?
thanks in advance
If you'd rather stay with OEM hubs, I have some. They're what's left from Tommy Morrison's C4 testing and race program. Factory packed with Mobil 1 lube. Probably used in one race or test session. This particular hub has been drilled to accept a larger stud.
PM me for more info, pix. [IMG][/IMG]
in post #6 you will see a thin washer on the left side of the splined part of the shaft. you may want to replace this washer because it is coated and it prevents noise that you might mistake for a bad u-joint or bearing. see ya
