Questions after cleaning rear ABS sensors
Just finished trans mounts and thought I'd clean the rear ABS sensors before putting the wheels back on. I've had intermittent ABS light coming on. During winter months almost never and issue, then in summer the light comes on often.
Folks here have suggested I clean the sensors. They were dirty. Interesting how the ferrous grime sticks to the magnetic sensor tip. I also applied Stan's favorite Dow Corning 111 silicone O-ring & valve lubricant/grease to the sensor O-rings.
The tone rings are the same on both sides (the later style with fewer and larger teeth), but the right side ring is unpainted and has a brassy appearance. The left side ring is painted black. This is perhaps consistent with the PO saying the left rear axle and/or wheel bearings were replaced.
I didn't clean the front sensors because I want to try driving it first to see if the problem was in the rear.
Are there other connection points in the rear that are often corroded or come loose to make an intermittent connection?

Check with wiring that goes from the wheels up toward center of car, over subframe and suspension. Mine was shredded up by the drive shaft. The outer rubber coating on the wires dried up and crumbled away. The inner cord shrinks up and the wires get all loose.

Yes...parts of the rear ABS harnesses have crumbled and look the same as above. But the wires haven't be damaged as far as I can tell. There's a bunch of poorly applied electrical tape I'll have to remove to be sure.
I'm still trying to figure out what is the best way to recover them, and if I should cut out the nylon stress cord because it's creating more problems in it's shrunken state. I'd like to know if anyone has used the self-vulcanizing rubber tape as a cure for he crumbling outer casings. All other solutions are looms or hoses that have to be slit lengthwise to accept the wires. Seems like a method to capture water and crud inside and eventually chafe the wires bare at some point.

check the connections in the spare tire well,
the vulcanizing tape works good for recover,
then add a piece of the ribbed wire sheathing

Bertrand - Now that's what I'm talking about. Thanks! I like Stan's idea to put the ribbed loom on the outside just for abrasion protection.

I cannot say one particular brand has ever worked better than the other and I'm sure you pay more for that stuff with the "loctite" name on it:

I have not seen this loctite tape but it looks very promising,
I have used the silicone fusing tape from NAPA its kind of brittle till you stretch it but it works well.

The spiral wrap makes a very slim, flexible, and self-secured outer casing. Thanks for sharing. How did you release the plastic harness anchors? I haven't figured out how they work and don't want to force and break something.

I have used the silicone self fusing tape in other applications and it rocks. This is what GM and others used from the sixties through the eighties and it might be easier to work with and less bulky:
