86 RR ABS Wheel Speed Sensor
Guys,
This has been a tough part to purchase. No one seems to stock them anymore.
I need a good source (and their part #) for the right rear ABS wheel speed sensor.
86 vette, 700R4 Auto
Thanks in advance,
Frank

I've got an (early) 84-86 Parts & Illustration manual. The original part #'s listed for the rear wheel speed sensors are 14084079 (LH) and 14084080 (RH). I'd email Chris at Superior Chevrolet, who takes care of many of us here on CF. Not only does he offer a discount to CF'ers (usually ~40% off retail), but he can often locate a hard-to-find part in some GM warehouse in god-knows-where.
The last email address I had for Superior is:
parts@superchevyperformance.com
You'll find mention of Chris, and his phone #, on various CF threads. Give him the part #. He'll look it up and tell you if there's a newer part # replacing it, and will search for it for you.
..just found his contact info:

BTW, I just had a dealer troubleshoot my 86's ABS - light has been on since I bought it 6 years ago. They found the connectors on two of the sensors were bad - intermittent (that COULD be your problem, if you have been measureing the continuity from the ABS module behind the seat). After charging me $250 or so to fix those, the light was still on. They appear stuck to go any further, because they've been unable to find an ABS test adapter, from any dealer they're called in the area, to fidn out from the ABS module what is still the problem. The first one or two years of vette ABS required a special tester or adapter to read the ABS codes. After that, they standardized the interface. But Chevy dealers have apparently misplaced or thrown away their test equipment for 86/87 vette ABS. So, good luck if replacing the sensor doesn't do it.

I heard that the 86 ABS sensor's were discontinued. Only 87 and up sensor's are available new. The problem is that the 87 and up sensors require you to countersink the hole in the pre 87 knuckles to fit properly becuase they are different.

Gregg, I gave Chris a call and he was unable to help me out. I think 86Pacer is correct on the part being discontinued.
While I was rebuilding the whole rear-end of the car I found my right rear sensor tip broken almost to the base of the sensor.
86Pacer, great job on the tech tip! This is probably our solution with our cars in the future.
Thanks guys,
Frank

Looks like you definately need to buy a new sensor now. The toothed hub inside the knuckle is probably damaged too. Here's how to retrofit 87 and later ABS Sensors to your pre 86 knuckles by countersinking the holes so that you do not have to buy 87 and later knuckles. BTW I am not the creator of these tech tips. I just came across them floating around on previous threads.

Best price for ABS sensors and other Dealer/GM parts I've found is at
http://www.gmpartsdirect.com/
I've found it to be cheaper that with Chris by several dollars.
Just enter the part number on the top left hand box. Only thing that sucks is no orders can be canceled once placed, and they say it usually takes 7-10 days or more before they even ship the parts to you. It's best to e-mail them and ask if your part numbers are in stock before you place an order. This way you are not stuck waiting for weeks for an order that you then later find is on back order and have no way to cancel it and get it somewhere else.
Superior Chevrolet's website (http://www.superchevyperformance.com/) does not let you punch in your part numbers. Their part number search feature does not work. So I was uable to place my order with them. I am not a fan of giving out my credit card number over an unsecured phone line either.

Unfortunately neither of these two Suppliers who offer discounted prices to CF Forum members ship overseas. I wish they would change their policies. Don't they know we are in the 21st century now and Corvette is a world wide brand name?

We spent $160 on the sensors and tried retrofiting them with the countersink but the light still came on.
To our amazement when we installed the sensors with the spacer and o-ring the light went off during first start but came back on when we shut the car off and restarted it.
This leads us to believe it is a defect in the design and the reason why no one will helps fix the problem.
I think car manufacturers are liable for the life of a car with safety systems so they won't admit there is a problem with the design.
We plan to install an 86 system without anti lock in our 87.
We will replace the lines and add a proportioning valve. This will be an easier fix and you won't have to worry about having the brakes lock up while far away from home as in our case.
It seems like the valves do not let the presure release and all the calipers drag. Not sure if it is the antilock or all my calipers started sticking at the same time. When we replace the line we will know for sure and post our experience.
