How do i test the rear abs sensor on a 2007 tacoma

You need a mechanic with a high level scan tool to check the Diagnostic Trouble Codes and Live Data. It is probably ABS Sensor related, but should never leave you with no brakes..

Check the trouble codes with a good code reader that will check the ABS system. Sounds like the ABS sensor on the axle brake is either missing, not connected or the wrong version for your truck.

you will have to dimantle rear hub withdraw driveshaft and replace seal oon axle drain axle oil first square drain plug in centre of axle hope this helps

Hub & Bearings

Adjustment
Check the backlash in bearing shaft direction and the axle hub deviation. Maximum for backlash should be 0.0020 in. (0.05mm) and for axle hub deviation 0.020 in. (0.05mm).

Front axle seal on 1997

this is very hard if you do not know what you are doing. Ill try to step you through this

• pull wheels
• drain pun-kin case
• pull rear cover
• in between the spider and axle sets pull C ring with needle nose pliers
• pull hub and axle out CAREFULLY as there are roller bearings on the end of the axle housing
• pull seal out at the end of axle housing
• tap in new seal CAREFULLY and straight DO NOT BEND IT or it will be junk
• replace axle carefully as the roller bearings are still there
• replace C clip to original position
• replace axle diff cover and replace the gasket with a new one
• refill diff case
  
• install tire
• your good to go
  

There is a sensor located on top of the rear axle.If it is unplugged it could cause your concern,but the abs lamp would also be on.

REPLACEMENT

HINT: The replacement procedures for the RH side are the same as those for the LH side.

1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
2. REMOVE SPEED SENSOR REAR LH
1. Disconnect the speed sensor connector.
2. Remove the nut and speed sensor rear. NOTICE:
• Do not attach any foreign matter to the sensor tip.
• Ensure that no foreign matter enters the sensor installation hole.
1. INSTALL SPEED SENSOR REAR LH
1. Install the rear speed sensor with the nut. Torque: 8.0 Nm (82 kgf-cm, 71 inch lbs.) NOTICE: Make sure that the sensor tip is clean.
2. Connect the speed sensor connector.
1. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL Torque: 3.9 Nm (40 kgf-cm, 35 inch lbs.)
2. CHECK ABS SENSOR SIGNAL

The ABS light is for panic stops. You have to have it put on a scan dino in order to find the right sensor that is not working or you could look at the sensor on the bcak side of the disc or drums and see if you see cracks in it. It might not be plugged in all the way since you had the axle replaced. Check all connection on back side of each brake. You would have to take it in to a dealer to find the sensor thats not working right they can pin point it.

Neal, it may not be the right front axle. I thought I had the same problem with 97 4Runner but it turned out to be the right rear axle bearing. Even the technican thought the niose was coming from the right front axle when he test drove it with me. Seems those rear bearings go out if you do a lot of towing with the truck. Cost about $ 400.00 to replace make sure they replace the ABS sensor collar and replace the axle breather tube vent ( they get plugged and when they replace the bearing , they have to replace the seal in the axle also and mine leaked after because of a plugged axle vent.
