I am going to replace the front wheel bearings and not sure which part # I need to order from rockauto..am getting the ones with Timken bearings....how do I tell if I have 2 or 4 wheel ABS.


2007 1500 Big horn
5.7 hemi
4x4
quad cab...not mega cag

 

ok..now I know that I have ABS ...Anyone know what the correct part number is

 

Just 'cause you have ABS doesn't mean you have four-wheel ABS. Two-wheel is required, four-wheel is optional. It might be that if the rear brakes are disk, you have it, but that may not be true.

Find a patch of wet grass, sand or gravel and nail the brakes. If the fronts lock up, you have two-wheel.

 

why does it matter if its 2 or 4 wheel ABS gonna have to find out for sure now what I have...was told first if I had disk brakes in the rear it was 4 wheel....guess that's not so.....

 

My '03 has "disk" brakes in the rear and only 2 wheel ABS. My disks brakes also have a drum brake for the parking. That's not a reliable test. Just look at the wheel hub and see if you have a wire coming off or not. If you have a wire coming out of it, then it's 4 wheel ABS. If you don't have a wire, then it's 2 Wheel ABS.

It matters in that you need the right part. It might be possible to use a 4 wheel ABS hub in a 2 wheel system, but not the other way around.

You can also look up your VIN and get a build sheet. It should say something on there about the ABS.

Simply Just check at each wheel front and rear and see if theres a wheel sensor at Front Wheel and rear if sensor is on front and rear wheels its four wheel ABS

 

OK...this is what I found...Driver side front..has wires coming out of hub
Passenger side front....NO wires from hub


And nothing on either side in the rear


By this...I would say I have 2 wheel ABS...correct


But why no wiring from the passenger side front hub...shouldn't there be ????

 

You won't see wires in the rear because that sensor is on the rear differential.

You should not have a mix of wires. Look up your VIN. The info will be there for sure.

 

OK..I looked up the build sheet and this is what it says about the brakes


4 wheel disc Rr Anti-lock brakes


Now what does that mean..im confused


4 wheel anti-lock brakes???


hopefully I get this figured out so I can get new hubs ordered pretty soon..


Thanks to all for the help

 

I believe that's 4 wheel discuss brakes but only rear anti lock. That's what mine says and I only have 2 wheel anti locks. I also looked at my abs unit and it only went to the rear wheels.
