Need longer stopping distance.

why is my 1991 Mazda truck surging at higher speeds
Higher g's produced at higher speeds are harder to survive.
Because your motor is spinning faster at higher speeds causing higher rpm's
it would most likely be the bearings but in some cases sometimes the axle make a humming noise when traveling at high speeds.(front wheel drive)
due to the preasure
Because at higher speeds you have more velocity than at lower speeds transferring more energy to make a bigger crashing causing more damage.
a.
The distance is 407.66 miles, time frame is roughly 6.27 hours traveling at speeds of 65 miles an hour, and 5.44 hours when traveling at speeds of 75 miles an hour.
The higher the speed the lower the miles per gallon will be. Higher speeds mean that the engine rpm's are also higher ... higher rpm's means greater gasoline consumption. Try going 10 miles and hour less and run a test on your mileage ... you might be surprised at the results.
Yes. It is doing more work at higher speeds and therefore is using more energy.
