WHY DOES MY CAR START TO SHAKE WHEN I GO OVER LIKE 65 MPH?

2007 Dodge Dakota • 110,000 miles

What could be wrong. Could it be related to the temp. Gauge showing it is a little low? Like it never gets to the half way mark where I think they are suppose to be. Starting to freak out is this a huge costly problem? Also I know all the tires are not at the same tread. I guess the guy I got it from replaced a hub but said it wore that tire tread down. Please help

Without more details or observations, shaking at higher speeds is typically caused by a tire out of balance. If the tires don't have matching tread, their different characteristics can cause the truck to pull to one side, vibrate, or pull during braking.

Okay and also do you know what it means if the temp. Gauge reads a little low like if it was suppose to be at 50 percent it never gets above 40 percent. I know its okay if it is a little less than half but I feel like its a bit too low?

Not to worry. Those gauges are notoriously inaccurate and are just meant as a guide. The temperature gauge on my '88 grand Caravan just squeaks by the half-way mark while pulling an enclosed tandem axle trailer that's bigger than the van, to an old car show swap meet the weekend after the 4th of July when it's really hot outside. The electric radiator fan will be running even at highway speed but the engine doesn't overheat. In the winter, the gauge struggles to hit the one quarter mark, but the heater will burn me out if I let it. That goes to show that the gauge just gives a rough estimate of the actual temperature of the engine. If you look at the gauge in a different truck similar to yours, you'll see it reads differently too. The main thing you should watch for is if it suddenly reads much different. Otherwise, anything between one quarter and three quarters can be considered normal and acceptable.
