Wheel speed sensors misadjusted, damaged , or metal shavings and other debree, since they are magnetic can give false readings from one of the wheel circuits. Over sized tires can give of false speed readings as well. there are many other causes including bad relay, control module, e.t.c. It is best to have the proper scan tool to diagnose an ABS problem

it is decieving. if the tensioner has an extension of about two inches from the base, it takes a 15 mm to lift it, be easy, make sure the wrench is not going to touch anything as you release it after taking the belt off

if you just changed the alternator you should do the belt too,if you get your belt from Auto zone or NAPA the belt routing is on the back of the package

Look for the belt tensioner pully. If you don't know what this is run the engine and look at the pullies.The one you want is the only one that will be moving up and down.This is the one that is spring loaded.Think it is drivers side top.It may have a square hole in the arm to put a ratchet in.Thinking 3/8" drive but may be 1/2" ,if there is not a hole then you will need a socket that fits on the center bolt of the pully.I will suggest a long handled ratchet or breaker bar,if you don't have one you can put a pipe over the handle of a short handle."cheater pipe"Put force on it so the pully comes up off the belt.If you don't have a belt routing sticker still on your radiator shroud draw one before you remove it.I think the belt comes off on the drivers side.when putting on the new one start at the crank pully,around the waterpump,then to all pullys on passinger side.The last one will be the alternator.Hold the belt down in front of the tensioner pully attach the ratchet and pull until you can slip the belt under the pully,Make sure the belt is properly seated in all pullys before starting.Helps if you have a spare set of hands.
