The Death Wobble

I don't know if any of you peeps are Jeep lovers but I have one and it has the death wobble...if you've never heard of that before well let me just explain it to you.

1. if you go over 30 your jeep will shake violently

2. there are a million reasons why you have the death wobble...luckily I found mine today.

this is what you go through if you have it. You take it to your local ATV shop and tell them you have the death wobble...they don't like that saying by the way...they take a look at my beauty and they find the reason right away....400.00 (that includes a courier fee that i have to payto get it from another store) wtf????? bushing....damn bushings is my problem. I said okay i need this done today (for obvious reasons) ie (NOT DYING)  he stated that nothing can be done today, well I say how safe is it. He comes back with "honestly (you know that can't be good) if it were to come into my shop he couldn't let it leave...its basicly a death trap at this point. So he says keep it below 30 mph and DO NOT GET ON THE INTERSTATE. hmmm well since I live so far from my job I have to go down a two lane road...do you knowhow many people I pissed off. So in the end I threw my flashers on and made my way home...safe and sound.

My everyday driver is a 2005 TJ Wrangler X, and I didn’t feel I needed a monster truck so I decided to go with 30-31" tires instead of the 27" that came on my TJ. To accommodate the larger tires, I was going to need to get a couple of inches more clearance for the tires. I ended up installing a set of 2 inch coil spring spacers to lift my ride height slightly. After I installed the spacers, I re-set the toe to 1/8" and drove the jeep. It felt slightly unstable, but I knew I tightened everything back up. I did not rotate, or balance my tires. Nothing else was changed. I drove my Jeep locally for the next few days to work and back (only 4 miles per day round trip).<br />
<br />
The next weekend I drove to Sacramento to visit family. When I reached a crappy rough highway (HWY 80) the front end felt wobbly. As I approached 40-45 MPH and I hit a bump on the right front, I got the sensation I was driving on triangle shaped front tires that were out of sync. My garage door opener and other crap on the dash leapt off onto the floor and my butt puckered! Scared the hell out of me. I slowed and it went away as I came to a stop. Every time I tried to go over 40 MPH the wobble came back with a vengeance. I ended up taking surface streets (keeping the speed under 40), until I found a much smoother roadway to take home. Once I was on a new stretch of Highway (N/B 99), I was finally able to get up to 70 MPH w/o wobble. Drove the rest of the way home worried I might die, but it drove fairly normal.<br />
<br />
The next few days, I searched the internet as many of you have I’m sure. After reading all the posts available, I started inspecting my jeeps front end. After 2 days of intense scrutiny of all the components, I came to the conclusion, nothing was worn, loose or broken. What the hell???<br />
<br />
I decided to purchase a magnetic base angle gauge ($5.00). I used it to check the angle of my CASTER and found it was over 3 degrees above spec. (top ball joint farther back than lower ball joint total of almost 11 degrees from zero). I ended up re-setting my CASTER back to 7 degrees and re-set my toe again to 1/8". Guess what? my wobble went away. Over the next few weeks, I put about 700 miles on it with everything in place as it was with the wobble. I even drove the same stretch of highway 80 several times to make sure the wobble was gone. I felt confident the disease was cured, so then I bought my new tires and rims. Now with an additional 600 miles on the new tires, I know I beat it. <br />
<br />
I’m not trying to say that all of you with Death Wobble (or what you think is DW) can decrease your CASTER and fix all your woes… What I am saying is it DID fix mine. <br />
<br />
I know that some of you will not believe this, but if you think about how a shopping cart with a bent caster wheel reacts when pushed forward, our DW does virtually the same thing. Think about how CASTER angle works, if you had lets say 45 degrees of positive Caster, your wheels would probably wobble at 10 MPH just by going over small pebbles. Anyhow, if anyone has questions, don’t hesitate to ask. For those skeptics out there, keep spending money on parts instead of thinking outside the box. I fixed my DW for about $10.00, how much have you spent trying to fix yours?<br />
<br />
Oh.. and before anyone asks...<br />
<br />
NO, I did not replace my steering stabilizer, shock, dampener or whatever you want to call it. <br />
<br />
As long as your alignment is set up right, there is NO NEED for one. <br />
<br />
No other parts were replaced or tightened. All I did was re-set the CASTER back to about +7 degrees.
