For my 2000 Dodge Durango SLT (4.7 liter V8, 4WD, all wheel

Customer Question

For my 2000 Dodge Durango SLT (4.7 liter V8, 4WD, all wheel ABS), I recently replaced my front wheel hub and bearing assemblies, came with new wheel speed sensors. Also replaced brake rotors and pads on both front sides. Had to press brake caliper piston to “bottomed out” position to accommodate new pads and rotor.
After work completed, I get ABS engaging on any brake action that gets me down to 15mph. If I drive slowly (~100-200 feet) and turn (like in parking garage) I often get ABS and parking brake light on dashboard. ABS obviously disabled after lights appear and standard braking works fine.
Have pulled ABS codes of 21, 22, 23, 25, 26, and 27. Can you help me figure out what's going wrong here?

hello I can assist you with this .

Customer: replied 3 months ago.
Super. Let me know if my original question has enough info for you to get started.
Expert:  Kevin Bourcier replied 3 months ago.

yes . as I understand it you never had any ABS issues prior to replacing the front wheel bearings / brakes correct ?

Customer: replied 3 months ago.
that's correct.
Expert:  Kevin Bourcier replied 3 months ago.

the new front wheel bearings came as " hub assemblies " with new wheel speed sensors included ?

Customer: replied 3 months ago.
Sensors were included. I believe they were distributed under Borg-Warner name and were ABS19 and ABS21 models. I will double check that.
Customer: replied 3 months ago.
Sorry, make that ABS 119 and 121 model speed sensors.
Expert:  Kevin Bourcier replied 3 months ago.

the codes you are listing , can you be more specific ? are the P codes or C codes or U codes ? ( such as P0021 )

Customer: replied 3 months ago.
For what it's worth, the passenger side had three or four shims included between sensor and mounting face on hub assembly. Driver's side had only one shim. I left those "as is" when I installed the new hub assemblies.
Customer: replied 3 months ago.
They were chassis or "C" codes. C0021, C0022, etc.
Expert:  Kevin Bourcier replied 3 months ago.

okay . thank you

Expert:  Kevin Bourcier replied 3 months ago.

first of all , are you certain that you have the front axle nuts tightened to the correct torque ?

Customer: replied 3 months ago.
I believe it was like 195 ft*lbs. We can double check that tonight.
Expert:  Kevin Bourcier replied 3 months ago.

the issue you describe is usually indicative of excessive wheel speed sensor / tone ring clearance . and since the problem did not exist previously I would look to make sure that there is not excessive play in either front wheel bearing .

Customer: replied 3 months ago.
Both sides seemed appropriately tight. I will check that again tonight.Do the shims play a part here? Do they make the sensors stand off too far from hub teeth?
Expert:  Kevin Bourcier replied 3 months ago.

here a description for one code . Shims ? there should be no shims under the wheel speed sensor . They should be sealed with an O-ring and posibly one thin paper gasket .

Customer: replied 3 months ago.
That text file appears empty. Could you please check and resend?
Expert:  Kevin Bourcier replied 3 months ago.

there should be no shims

Expert:  Kevin Bourcier replied 3 months ago.

try this . Sorry

Customer: replied 3 months ago.
OK. I can read the RTF version. Can we revisit this discussion after I get a change to pull the shims, check bearing runout and clearance, and verify proper torque? May take me a day or two....
Expert:  Kevin Bourcier replied 3 months ago.

okay , sounds good
