Turn off the diff lock? The abs light comes on with the diff lock engaged. The tires will squeak because it is locked together and the two wheels cannot turn independantly. You have the 4.30's in pretty sure. If they worked before, i bet they would work now. Try making sure hte diff lock is off. (the light turns off completely not blinking, or solid)

You may have to drive it around a bit to get it to disengage. Post back after youve done that.

 

A= 7.5" ring gear
04= 4.56 ratio
A= 2 pinion, open

Any updates??

 

well the diff lock was stuck, so we had to take out the whole differential case out and manually release it since when i tried to disengage it with a flat head it wouldn't budge, now everything is alright. but sometimes the abs likes to kick in.

 

Nice, I think someone said that you're diff is engaged in the beginning of this thread

 

yup thanks for whoever gave that suggestion, i thought i had unlocked it when i put it back on the first time but i guess it got pushed back in. any suggestion about the abs now? would i need new sensors?
