Hi everyone! Recently my 95 Dakota 2wd shudders a little when coasting from 40mph to 25. It started after I got new brake lines, hoses and rear wheel cylinders, but I have yet to put in new pads and shoes, hardware and drums, which are shot. BTW, I guess I haven't had rear brakes for about a year. My ujoints have been squeaking a lot too and have to be replaced.

 

when coasting (letting off the gas pedal) or when braking (applying brakes)? Do you feel the shudder through the steering wheel or only in the rear?

 

When coasting, I can feel it in the seat and sense it's coming from the rear of the truck.

 

I'm going to guess pinion wear in the diff, but wait for someone else that knows better than me. When the engine/trans is driving the drive shaft, the teeth are meshed on one side...but when you coast, the wheels are now turning faster than the drive shaft and the teeth hit the other side...so wear gap can cause shudder.

 

if you coast down in neutral is the vibration gone?

 

It could also be one of the tires.
