Front end shakes constantly

SOURCE: shaking/vibration in front end & steering wheel

Nor sure about the 2001 model, but on the 97 model, the track bar bolts to the frame on the driver's side. The bolts work loose. Dont merely look at it, go ahead and tighten them. There are two bolts facing upward, at the end lf the track bar. Then there are 3 nuts behind the driver's side front wheel that need to be tight. You dont have to take the wheel off so see them. I tightened all of mine and the death wobble nearly went away ....( 90%)....then I replaced the steering stabilizer ( damper). Hope your 2001 is just as easy !

have a tire shop balance your front tires.

My Death Wobble started immediately after I installed a set of Coil Spring Spacers (to lift 1.75 inches) on my stock 2005 Jeep Wrangler X. Turned out, the DW was because while changing the height, I also lowered the CASTER angle in the front end. So, to fix it, I could have purchased a set of eccentric bolts for $50+. Instead I went out and purchased a piece of 1.5 inch flat bar for $10 from OSH. I cut out 4 1.5 inch squares. Then i drilled 7/16 inch holes centerline, but close to one side (in exactly the same place) on all for squares. I then removed the lower control arm bolts, nuts and washers. I installed these square offset washers I made so the front axle would be pushed forward (to increase the Caster angle). The toe setting changed a bit, so I reset them to about 1/8 inch toe in. After driving my Jeep, I noticed there is no more DW. The steering wheel was off center, but after 3 attempts, I have that perfectly centered. I have every intension of having the alignment checked, but not till after I find the new tires I want. If anyone is interested, I can draw out and photograph the cure and send it to you.

sounds like the steering box has gone bad on you. This problem is common in jeeps and 4x4 trucks

SOURCE: the front end and steering wheel shakes when i hit a hole or bump

This usually indicates a problem with the suspension components. Check for play in front end suspension, 1st thing I would check would be the steering damper, it's often overlooked, and could be the cause. If that checks out ok, jack up and check for play in wheels, which could be caused by worn ball joints, tie rod ends, wheel bearings. A lot of possibilities, generally play in any components can trigger the shaking you're experiencing when hitting a pot hole or bump. Good luck!
