'97 Ranger "grabbing" off the line
I just bought a '97 Ranger XLT standard, 2WD, 4.0L.
I've noticed a couple times now where the whole truck vibrates at highway speed, so bad I think the truck's gonna fall apart. Then a few minutes later it's smooth again. This happened to me tonight again, then when I tried to leave the gas station, something was seriously "grabbing" when I tried to get going. It felt like the brakes were locked up as I tried to get off the line. It took half a dozen tries, and even then the truck felt jerky for the few blocks to home.
I haven't looked at anything yet, but I thought I'd fish for ideas or similar experiences. Brakes, parking brake, maybe transmission? Not sure what to think, any help would be great.
