Probably some sort of balance issue. First suspect is tires, less common is drive shafts. HAVE IT CHECKED FOR A WORN OR LEAKING STEERING DAMPER
If you are in Full time it is recommended not to go over 25mph that is probly why it shakes put it in part time you can go up to 55 mph in part time
check and replace tires and tie rod ends as neccassary
my jeep was doing this and they told me all this stuff that could be wrong with it and i got my tires rotated and it fixed the problem..
You should have the wheel alignment checked. Could be a $20 Fix.
because Jeep Wranglers are easy to flip, especially turning at high speeds.
Have you noticed if the shaking happens more when accelerating or just cruising at that speed? Read More
A shake that is that speed sensitive is usually a bent rim, or bad tire.
If an ATV is moving at 55 mph, then its speed is 55 mph. Both the original speed and the converted speed are the same.
Flat out on a level road with a good wind behind you, probably 55 mph.
55 mph = 88.51392 kph
To find the percent increase from 55 mph to 70 mph, you first calculate the difference between the two speeds: 70 mph - 55 mph = 15 mph. Then, divide this difference by the original speed (55 mph) and multiply by 100 to get the percent increase: (15/55) * 100 ≈ 27.27%.
55 mph * 1.6 = 88 kmph
