replaced front hubs, now ABS light is on

[djohansen]

I had the shop replace my front hubs on 97 4WD Ranger, now the ABS light is on at the dash. It never came on before, could they have put the wrong hubs on or done something wrong? They put the Ford hubs on, $340 apiece, not the cheap lockouts.

well before you look at anything go under the differential (i think on your year truck.) and see if the abs wire is connected to the differential.

If you have four wheel anti-lock,the sensor(s) may have been damaged during the replacement.For that kind of money,I would be returning to get it ironed out.

Can you explain this further? Where on the diff is it connected, and where does it come from?

Sally, are you having the same issue?

The rear speed sensor-located on the rear axle housing.

from autozone

this system is used on the Mountaineer and 1993-99 Explorer, it was optional on all 1995-99 4-wheel drive Ranger models.

The 4WABS system consists of the following components:

1. The anti-lock Hydraulic Control Unit (HCU)-mounted to a bracket which is bolted to the left-hand inner fender.
2. The Explorer/Mountaineer 4WABS module-located on the outboard side of the left-hand inner fender, behind the plastic fender liner.
3. The Ranger 4WABS module-located in front and to the right of the battery, on the radiator support.
4. The front wheel sensors - bolted to the steering knuckles (4x2) or, on Explorer/Mountaineer (4x4) they are part of the wheel bearing assembly and on Ranger (4x4) they are part of the front axle assembly.
5. The rear speed sensor-located on the rear axle housing.
6. The front speed sensor indicator rings-located on the front rotor assemblies (4x2) or, on Ranger they are pressed into the front wheel hub and spindle and on Explorer/Mountaineer (4x4) are integral in the front wheel bearing assemblies.
7. The rear speed sensor indicator rings-located on the ring gear inside the rear axle housing.
8. The Explorer/Mountaineer G-switch-located on the left-hand frame rail aft of the No. 2 crossmember.
9. The Ranger G-switch-located on the left-hand frame rail forward of the No. 3 crossmember.
10. The Explorer/Mountaineer main and pump motor relay-located in a four relay box mounted near the battery on the left fender wall.
11. The Ranger main and pump motor relay-located in a two relay box mounted near the master cylinder on the left cowl side.


my money is on any anti lock components i made in bold in the front since that is where the work was done at but it does help to check the connector to the rear.

the one underlined would need to be checked by a pro, since it is deals with the gears in the differential.

and there may also be codes stored

this link should help further http://www.autozone.com/servlet/UiBr...3d800be19f.jsp

another thing to consider with the original poster is it worked before the shop broke it they should fix it for free

Ok, so then this is something the shop may have messed up in a front hub replacement? Wow, I have already had it in to them 2 times, I guess I should take it back again? I am now nervous. It is a reputable shop, Aamco Transmissions.

Some Aamco Transmission shops are franchised. I've had some dealings with them and at times I get this song and dance about their thirty-tow point transmission check. Nonetheless, I think they owe you a complete and successful repair which you paid for. At times these people tend to pull your leg so you have to be firm and confident. Good luck.
