anti-lock light on after removing rear hub -- 99 Disco I

[Apexdisco]

I finished the job of replacing my rear hub bearings (and oil seal) last night. I discovered the "Anti Lock" was on this morning.

Here's some background info.

A week ago - discovered grinding noise coming from driver's side rear wheel. Noise was intermittent.

- inspected rear brakes and the need replacement.
- replaced both rear brake pads

No "anti lock" light for several days after brake pad install.

Two days ago - grinding noise gets louder and more pronounced when vehicle is turning. Decide only thing left is to tackle replacing bearings.

- jack truck, remove wheel, remove caliper, remove axle rod.
- dissasembled bearings, clean all surrounding parts/components, reassemble.
- problems getting hub on correctly and tight; after several frustrating hours, problem is now resolved and I am confident hub bearings are installed correctly
- reinstall caliper, bleed brakes

This morning light is on after several start and stops of the truck. I searched past threads for any clues but am not satisfied. My guess is the sensor is needs to be adjusted or reset somehow.

You all have any clues?

Try re-seating the sensor on the back side of the hub. Push the sensor in until it stops.

so this can be done with the wheel on?

Just push on the black wire?

 

[Clay]

Yes. The black wire connects to a disk about the diameter of a nicke or dime. press on the disk. It could move inward as much as an eighth of an inch.

As far as I can tell, you have to disassemble the whole thing just to get at the sensor (silver disc).

Too much work for tonight. What a pain in the @$$!!

Use a screwdriver (slotted) and a hammer and tap on the sensor. Place the screwdriver adjacent to the wire and be gentle. It will move. Wheel can be on, with the truck on the ground. I have never been able to seat the sensor by hand. Good luck!

Exactly - sensor pushes in from the back side - just go under the rear axle - follow the sesnor wire and gently tap the sensor back in place until it stops- that's all there is to it. Nothing to disassemble. It's just like the front sensors, but in sideways instead of up/down.

Thanks, I'm going to give a another shot at it tonight.

"anti-lock" light ---> FIXED <---

Thanks, guys. I can't believe how easy that was to push back.

No more annoying light.
