violent vibration and knocking sound.
for the past couple of weeks, i've noticed a vibration in the steering wheel right at 43mph. friday i was towing a small boat, and man, it was really bad when i was towing it. at other speeds, there is no vibration whatsoever.
i figured it was the tires out of balance, as i've had this issue before on other vehicles, so i brought it to get balanced. i actually had it done twice, because i didn't trust the first place.
there is no difference. the other thing i notice is that when i'm making a left hand turn, and i hit ANY bump, even a rock in the road, i hear and feel a knock coming from the left side of the front end. i feel the knock in the floorboard of the jeep.
my jeep is a 2005, with only 11k miles on it. i've looked underneath, and i don't see anything loose, but i'm no mechanic. it does have a 2.5 inch lift on it, and i inspected the shocks, etc. no dice.
any idea what could be causing the vibration and the knocks?
