About 4 days ago I was traveling 30-50 mph and slowly my truck began to vibrate wicked hard. The windshield wipers the seats were all shaking and after 3-5 mins it would stop. This has happened about 6 times in the past four days. I thought it might be my e-brake release cable but its not cold out and I have only been traveling on the pavement so I'm not sure. Any ideas/ or anyone experience this? I have 16K on my FX4

 

Do you use the e-brake?

 

I use it once in a while, but the times it started vibrating I wasn't using it.

 

Theres a good chance its stuck. Just take it in and tell them you think the e-brake is sticking.

If it doesn't fix it than at least you know its not the e-brake.
