I have new shocks(Bilstein 5100's), a DSS stabilizer, 5 month old Pro-Comp stabilizer shock, '03 trackbar conversion, and BFG All Terrain 315's.

I STILL HAVE THE FRIGGIN VIOLENT SHAKES WHEN I HIT POTHOLES!!!!!!

Any suggestions for what else I need to throw money into? I am getting real close to selling this rig.

 

it's a caster problem caused by the 2" lift... have an GOOD alignment shop dial in as much negative caster as possible... if that doesn't fix it, get some aftermarket arms that will allow you to get the required caster setting. don't just walk in and say, "I need an alignment"... walk in and TELL THEM what you want done... if they look at you funny, walk out and find someone who knows their *** from their elbow.

and don't sell the rig... push comes to shove, just ditch the 2" lift, and you'll probably be fine.

Check tie rods, ball joints, wheel bearings, track bar etc......What is the alignment set at?

 

it's a caster problem... this is a NOTORIOUS problem with the 2nd gen 4x4 trucks when you put the 2" leveling kit up front...

even bone stock trucks that are on the wrong side of spec as far as caster will give you the death wobble... sometimes you can mask the problem w/ steering stabilizers, etc. but the problem is caster... if you can't dial in enough caster on the alignment rack, you either need to remove the spacers or get some aftermarket arms that will allow enough caster.

Well I guess its gonna go on the rack tommorow.

 

Before going through all that
Check the FIXED side of the track bar. If that hole is ovaled out, you can throw parts at it all day and night.
If that end is sloppy, the hole itself, not the bushing. YOu will need it repaired prior to an alignment or any other parts.

 

Yep caster and all track/control arms all need to be realigned back to stock specs. So with the lift you need to compensate. If your shop can't gett 'er done take it to a 4x4 specialty shop. These guys who build custom 4x4s deal in death wobble for a living. Nothing more scary then a short little jeep on 37" tires and bad case of DW at 70mph

 

If you run out of things to try, go ahead and rotate the tires. I went through my whole frontend and it ended up being the tires. Have no clue why but it worked for me.

Good luck

 

you could also try playing with tire pressures, up and down. Like Forest said, make sure the front end shop is a good one and knows about the wobble problem or go somewhere else.

 

Yes indeed! I own an offroad shop in kentucky and death wobble on Chrysler 4x4 vehicles is a problem we encounter all the time. I had an an 03 3500 death wobble at stock ride height with low miles just yesterday. I think it's just a chrysler thing.

Something about the geometry of the suspension, when reaching a point of sudden compression and decompression, sends the front suspension into some type of inertia. Another thing you want to check is your steering. I'm assuming the steering isn't a "conventional" tie rod and drag link configuration where each link is indivudual. The drag link runs from the steering box to the pass side arm, and the driver's side ties into the drag link forming and "inverted y" style steering.

Since the draglink position at the top is, (for the most part) static, in relation to a vertical postition, when the suspension compresses and decompresses, the toe in of your tires will change. Toe out on compression, in on decompression....I think this has a drastic effect on the occurance of "death wobble" too.

Does your truck have a drop pitman arm?

 

I finally experienced it last night and it scared the stuffing out of me. I never had this problem before when my track bar was shot and when I had my 2" leveling kit on. Now, a little over a month after I put my lukes link on, it does this. What gives? I'm gonna "adjust" the link and then get it aligned. I'm taking it to a shop that does big 4x4's and RV's and stuff. So I just tell them to dial in as much negative caster as I can? What's that gonna do to my tire wear? Will it affect the handling with my lift? Thanks yall.

 

Im almost getting tired of shourting this warning. If you have a new lukes link, or a new bar. Look at the other end!!!!
Hopefully someone will see this, check it and repai, before flipping a truck someplace

 

smokefrom4, mine was caused by the drop bracket from my lift kit being held on by 4 threads of the bolt that held it in place. The other end is fine on mine. Nice and round. Could probably use a new bushing but it ain't that bad.
