Re: service electric brakes .. brakes locking up

dont know if there drums or disc in the rears but if there drums good chance you might need wheel cylinders, but since the abs light is on could be a abs problem check the fluid

Re: service electric brakes .. brakes locking up

the brakes dont lock up .... they act like there binding or pulsing ..... the front and backs do it ... only when turning sharp and only in forward ......makes me think its a brake problem and not axle bind problem .....i guess its the brakes ...... someone has to have had this problem before ..... if i take it to the dealer im i gonna get raped ..

Re: service electric brakes .. brakes locking up

Mine had the same issue at 50K miles (05 limited hemi). It was a wheel speed sensor. That combined with a broken front differential mount. All fixed at the local jeep dealer for a premium.

Re: service electric brakes .. brakes locking up

i just replaced both front speed sensors ..... still doing it .... i do have the clunk when shifting .... after putting on lift ...it is the top mount , almost completly gone ... should i try rear speed sensors or take it to the dealer and let them pinpoint it ? ive spent 70$ on speed sensors so far from dealer ....

Re: service electric brakes .. brakes locking up

Mine did it too. Was a wheel sensor. I took it in , they located bad one, ordered & put on (mine was a front one) for about $150 or so IIRC.

Actually they changed both of my front sensors 'cause the tech removed AND BROKE the wrong one 1st.

Re: service electric brakes .. brakes locking up

You're experiencing the stability control trying to keep the vehicle from rolling over,thats why it only happens when making sharp turns. With the lift the truck gets "confused" and will kick in early. Your stability light shouldn't be on all the time, only when it's trying to control the vehicle.
