Yea - THANKS for placing that %$#@! rear ABS sensor in the most obscure location possible, for making it out of PLASTIC (so it has a premature failure rate) AND making the connector plug nearly impossible to disconnect from the actual sensor!

%$#@! morons.

Why not install the rear ABS sensor at the REAR WHEELS like 98% of all other Manufacturers do? Who in the F thought it was a great idea to install it on top of the pumpkin, sandwhiched in between the top of the pumpkin's casting, directly below the bottom of the rear floor pans, super close to the exhaust & frame, let alone with the spare tire blocking access as well?

Oh and let's not forget the SECURITY CONNECTOR that is on it! WTF man, there's no need to have that type of connector on such a part, especially when the part is mounted VERTICALLY and there's virtually no possible way at all the connector would EVER come unplugged!

%$#@! morons.

I had the XLS's rear jacked up high and safely supported on jack stands. I crawl under the rig to get to the rear ABS sensor and this %$#@! thing is practically impossible to get at (let alone getting your hands, arms and body all misconstrued). I dropped the spare wheel all the way down and even w/ that out of the way, accessing the ABS sensor was still a royal PIA! I could not get the dang connector unplugged from it before dismounting the ABS sensor from the pumpkin. I tried everything - then once I was able to get the ABS sensor down off the pumpkin, I saw that the actual connector was made with a red locking tab that had to be slid forward, then you push down on the inner tab to release it from the sensor... WTF.

I've worked on many vehicles, asian, german & many domestics - including modifying, dismantling & reinstalling major components in many Mustangs - and I've never been more pissed and wanted to destroy something while trying to replace something SO SIMPLE like an ABS sensor. It should have taken me 30 minutes or less to do, but took nearly an hour because of the freaking location and obstructions!

Good luck to any of you who still need to replace your rear ABS sensor - have fun. That's the WORST location EVER for such a sensor and I'm happy it has a high failure rate, as I surely can't wait to go and replace it again after this 2nd one prematurely fails....

Wait until you need to replace the heater core. :p:
 












Either that, or some poor ******* you can trade it to. ;)
 






Gotta love the first gen's, not many parts that are just really hard to work on with it.

Oh, and the heater core comes out in like 30 minutes on these things. Cake.

And my rear ABS sensor still works after 14 years :p:

Sorry, just busting your chops a little. Don't hurt me. :wavey:

Yes, but you should search on A4LD and checkout how many people have had transmission problems. :p:
 












Back to the original topic...

The reason the sensors aren't out at the rear wheels is simplicity. The XLS in your year used the standard three-channel ABS system (front left, front right, and rear). There's no need to monitor the individual axle speeds on the rear end, so why spend the extra time and money installing a pair of sensors that aren't needed?

Now, if you have the stability assisted vehicle (RSC-equipped), that uses a 4-channel system which has the sensors at the wheels like you seem to like.

As for the connectors, ALL connectors on the truck need to be security connectors. If they weren't, they would find a way to come loose, and you'd be *****in' about that instead; about how they couldn't spend the extra $.02 on a connector with a latch on it... Now that you know how it comes apart, don't you think you could probably release it in-place working blind?

The fact that it's plastic has nothing to do with the failure rate. They've been plastic for 20 years.

Keep in mind most manufacturers don't engineer their vehicles with servicability as a high priority. They design them for ease of ASSEMBLY, not disassembly. That ABS connector likely gets installed long before the rear sub-frame is even attached to the vehicle... It likely arrives at the assembly plant installed in the diff, then the diff gets mounted in the sub-frame, the sub-frame gets mounted to the chassis, and then the wiring loom gets installed. At that point, the body is someplace else in the assembly plant (likely the paint shop) and the worker can stand reach the connector unimpeded.

It's a simple design... One connector, one screw, and it pops out. But as with everything, location, location, location.
 






Mine went out too, but the dealer had to do it under warr i was lucky.
But try the CPS sensor on a jeep b----h of location on that one too. i spent over an hour getting to that one bolt about another hour trying to wiggle the sensor out. .
when it was done i wondered if dropping the transmission would have helped as there were only 4 bolts holding it up . . turns out in reading some do. .

Could you drop the Diff just enough to clear? Looks like 2 big bolt holding it up? Of course everything is still attached but might you get that 1-3 inches to help.
 






lol mine went out 2. but it was under warnty and the dealer replaced it
 












I replaced mine. I raised the left rear wheel off the ground and used my crawler to slide under the truck. You set your ratchet around top of the axled right onto the bolt and then reach around right side of axle and wrench it from that angle. After you pull the bolt off you can reach back over the axle with your left and and remove sensor to bring it down for you to disconnect it. It was a pain, but I had mine replaced in a few minutes not including using jack. I did it all by feel once I knew where it was. I wonder who the damn genius was that put the sensor in that spot. I bet they did it with out body on frame...lol
