What would cause the front end of a Jeep Wrangler Sport to shake at 65-70 mph?

Answer 1

I have a 2001 Jeep Wrangler Sport, mine did the same thing. I do not know what it is called but you have a shock that needs to be replaced. This is not a tire shock,,,,but you have a shock in the front of your Jeep between the front tires,,,,put your nose under the jeep and find it now,,,,,,,,,,OK now that you found it (I think it is called a stabilizer shock)I do believe the price will be less then $ 40.00 call around I had 2 different prices on the same shock,,,,do not try to install your self,,,unless you have a torch to cut the Stabilizer off. (if you live close to a mechanic ask them to cut it off, I do believe for $ 10.00 they should help you out,,,put the stabilizer on......let me know if that fixed it.....ditto504y@Yahoo.com Tires out of balance, a bent wheel, or tire with a broken belt. A vibration that can be felt in the front or rear at exactly 65 MPH and disappears at 72 MPH (assuming good inflation) indicates a tire balance problem. The Jeep CJ and YJ series are notorius for this vibration. If the vibration is present under 65 MPH you should suspect a 'Universal Joint' or, since it's a Jeep, a warped drive shaft. -- JJohnson Another Answer: I found it was my tires. They're rated for a truck, and because the Jeeps lighter, they caused vibration between 48 and 55 mph. I simply dropped the recommended air pressure of 50 something to 25 psi and it went away. The 4WD guy said if I wanted to do it perfect, I should do tire prints, using the pressure that shows a full track from side to side.
