possible differential issue

94 ranger 2wd 2.3 - abs and brake light on. i have brakes on all for corners.
the truck is experiencing resistance and a noise is coming from the rear of the truck. i suspect something in the differential. i jack up the rear end put it in to gear and the passenger wheel was spinning faster than driver side.

Reads like E-brake is stuck, could be rusted cable or bad slave.

Very rare to have differential problems with Rangers.

Get your AXLE code from the drivers door Sticker, then look here: Ford 7.5 & 8.8 Inch Axle Tag & Door Codes

To see what axle you have

backstory when this started happening i had no e-brake and i knew i had a wheel cylinder leaking. i'm carpenter by trade mechanic because i have to be. so sometime things get put off. Tuesday i went through the whole braking system and fixed everything. e-brake works now and it only does it while in gear and the wheel its doing it on had no e-brake.

----------

the sensor being bad doesnt make sense since it only happening at one wheel. there is only one hydraulic line running to the diff and then it splits to each wheel. if the sensor was sending a bad signal it would bind both wheels. but i do agree cheap sensor like $15.

did you fix the wheel cylinder? You mention e-brake working like it should but just for clarification.

Also, is truck a limited slip or open diff?

Look at the door label then at the link I posted above to see what axle you have.

it seems to not do it w/ the drum off. so i believe the shoe is causing it to bind. i guess the next step is a short test drive w/ no drum. i starting to seriously suspect low gear oil is causing sensor malfunction like some suggested on another forum.

You will NOT have brakes with no drum on, you will need to plug that brake line or you will lose alot of fluid when you hit the brakes, pedal will just go to the floor.

i believe you maybe incorrect. the spring holds the shoe in place which which keeps the piston from coming out of the the wheel cylinder. my ol lady was pressing the brake w/ the drum off so i could see the brake shoes in action. no fluid loss. can't be worse then running w/ a known leaky wheel cylinder

another scenario i just thought of is the axle running out of round. causing the drum to rub against shoe. the weight of the tire on when it was on the jackstand would bind it up and the weight of the truck would bind it up on the ground. likely cause worn out outer axle bearing. will check for play in the morning.

Nope, not wrong, springs return the shoes after braking but without the drum the pistons will push themselves out of the slave, way way worse than a leaking slave or caliper, it's a wide open brake line

on the dog leg, adjust the shoes with the star adjuster. you also have a lot of metal shavings sitting around. when you got the brakes done, someone didnt know what they were doing. there shouldnt be metal shards in there.

those aren't metal shaving. what happen was the brake fluid from the leaky cylinder ate the coating off the shoes and is making everything shiny

temporary fix

i removed the drum on the drivers side and put a plug in the brake line block on top of the diff. no more dragging. i got brakes on 3 sides. i know be careful. i am, i nvr drive over the speed limit.

the abs and brake light are still on. the abs light doesnt bother me the brake light does. i believe its a sensor.

here a little more backstory - before the brakelight came i was working at a guys house. i got done got in my truck and i had no fuel pressure. had a buddy take me home and took the ol lady's car in the morning to get the truck. it starts right up. got it back to the house and again no fuel pressure. that ended up be a dirty connection in the relay, fixed.

get in truck the next morning about to drive off and i notice the brakelight on. i dont drive it fingering its the leaky cylinder. i get the new cylinders that evening. next day or so i fix the rear brakes. light doesnt go off. so i go through the whole brake system making sure i got good pressure, no leaks and everything is working. now i'm where i'm at today. i may take a look at the schematics.

and no i don't do rear brakes everyday but 95% of the time (over the course of 20yrs+) if i can get it apart i can put it back together. and that goes for damn near anything.

the adjuster is all the way in. so what you're saying is open it up a bit and it will push the shoe up? i can see that possibly working.

i may look at the brakelight switch on the e-brake could be just stuck.

somethings i know and am beginning to believe.
#1 i for sure have brakes.
#2 i am seriously thinking its the e-brake switch that keeping the brakelight on.
#3 after 99offroadrngr mention the star adjuster i am beginning to believe that they gave me one for a 10" drum. why do i believe this because the other side all those parts were good so they got reused.
