Default a problem or just common in rangers??

so i got a 96 stx auto trans. the truck has 153,xxx with orginal trans and engine. i was wondering if all the rangers do this. when coming to a complete stop it seems to jerk i mean little, but when letting go of the brakes to go it jerks too. i was told all trucks do that cause of the weight. but i figured i would see if you all had that. i just had the filter and fuild changed. the dealership found no medal shaves or anything. i just had the suspension replaced and im not gonna lie its rough. they ran a test and it shifted good. so idk. its annoying me right now. but i was told that i got a small leak and that the pan needs to be replaced which i just bought and plan on doin that tomorrow. any ideas would be greats. thanks

My dads f150 does that only when his rear gas tank is not full

My truck has never done that and I have never heard of a common problem with it in rangers

Ditto, but mine is a manual. I have driven many different trucks and never had the problem. It could be the transmission or the engine stumbling at or around idle when slowing or accelerating.

when i had the work done the dealership check the engine and trans and they found nothing wrong but the trans did have a leak. they did an dynostic test on the engine and its in good running order and has good ideling. trans has good shifting points on the paper. so idk im lost. i had my gf dad look at it. he said it might be the rear brakes not grabbing tight. as far as that i had the dealership and another person who loves rangers look and they cant come up with anything besides the brakes or the leak( which i highly dout cause its very very slow. i got parts anyways so its not gonna be there much longer.). plus my fuild level is super good. so who knows.......

I don't trust most of what a dealership tells me. I had recently replaced my camshaft position sensor (cps) with a napa unit because the original started making noise (a problem w/3.0). After replacing the unit and after driving more than 10-15 miles on the freeway it would throw a code indicating a problem with the cps. I had just recently relocated to N Idaho and didn't know anyone to check it out. I took it to the dealer to have them just replace it. They came back and tried to tell me my mods (aftermarket sparkplug wires, hipo alternator and cai) were causing the code and wanted to charge me $400 to diagnosis the problem. I told them the problem was the napa cps and just replace it. It was replaced and now no problem. This is just one example of many experiences with dealerships over 40 years.

I can understand the brakes causing the problem when you stop, but not necessarily when you start out. To check the brakes, take it out for a test drive. Get up to speed and put the trans in neutral and brake from there. If it acts up it may be the brakes. If not it is probably somewhere else in the drivetrain.

Also when did the problem start? Was it gradual, just start one day or did it occur after a service. When was the last tune up? It could be a dirty iac or failing tps causing the engine to stumble as it drops and starts from idle.

This is just a start, I'm sure there are others out there that can add a few ideas.

i bought the truck from a ford dealership. its been doin it since i bought it. i trust the dealership cause my whole family dating back to my great grandfather on both sides of my family worked for ford. my father knows the service guys cause some of them worked under my father. so idk. its bugging me cause it feels like weight shifting but feels like brakes too just cant find this problem. I 99.9% sure its not the drivetrain or engine or trans. i just went offroading and did not worse or better. but if it was a trans or engine im sure something would of showed up. but who knows. i got under the truck and looked around and the drive shaft looks really good with sus and i looked under the engine and it looks really good. i didnt look at the trans but if it had good shift points and no medal shavings then i highly dout it is. i think out of my own mind that it is the suspension. i just put 1500 in new parts for the sus and its really rough. every little bump is like an earthquake. but like i said who knows. im gonna keep searching but if you got any ideas post here and i will look at it. thanks guys

It sounds to me like you have sticking calipers from your discription.
Jack car in N turn wheels. Smooth, dragging, stuck?

could it be the brakes grabbing and letting go it has rear drums right this is where you need a break shoe spoon back of the rears one or two clicks and see if it still happen if it dose then put the clicks back and if it don't go get shoes and do the brakes

My 02 did something similar after a panic stop one night, this continued for a month, then went away. I didn't get used to it doing it either.
I always suspected it had something to do with the ABS computer. I have tried to remember if I did anything different that might have caused it to go away.

You get your issue fixed? If not, check to see if your vehicle has any service bulletins out relating to the issue you're having. The reason I say this is there is a service bulletin out for mine for a similar issue and they are recommending changing the rear drive shaft. They claim clunking/thumping is caused by axle wind up during acceleration/deceleration. The fix is to change out the 3.5" rear drive shaft with a 4.0" aluminum drive shaft for around $650.00.

I have the same problem mine is an auto 98 with 4.0 engine. Just had the trans redone completely b/c overdrive button was flashing. They told me the overdrive clutches were worn. Anyway that is fixed but that slight jerk is still there on stop and go. When I put tires on the truck the shop told me it felt like something was grabbing and to check rear drums. Haven't done so but I'm trying to figure it out also
