I added the Lorenz sway bar drop blocks when I put the leveling kit on. Not sure that is the cure but I have not had the death wobbles.

 

Yep odd's are you will have to max out the caster.. I had too before my new tires!!

 

wait a minute... you were doing over 100mph on washed out tires????... Death wobble or death wish?

 

100 120km an hour that like 70 75 i guess it only happens when i hit a bump. and i don't know how to tell the differnece between a wooble or a wish...felt like the axle is hopping oppositie to each side.

 

hahaha... oh ok... i see that you are in Canada, hence the KPH....

 

Yes........Canada........eh!

Mine "Death Wobbled" stock, but no issues since tires,shocks, and a DSS steering stabalizer. Mine went completely away at any speed after DSS. Your tires may be enhancing the steering shimy as well.

Talk to Shane/Shawn (can't remember his name) at Lorenz Industries. After I spoke to him, I am in agreement with him that there is no aftermarket steering stabilizer shock that is better than OEM unless your willing to spend over a $1000 on a Carli dual system.

The DSS was just over $200. He recommended it to me. Available at a place in Red Deer.

 

Don Thuren has a stabilizer that's better than stock for $265. KORE sells one also but its quite a bit more. Carli's is nice but for $601 I expect more than emulsion shocks.

 

1.drop pitman arm
2.drop trac bar braket
3.drop sway bar brackets
4.make sure hubs, ball joints, and tie-rod ends are 100%.

 

I have a Dual Skyjacker sablizier system on it...I have a real bad univiersal and bearing in the front end on the pass side and it seems like thats where it all starts at when iam holding the wheel, i can make turns on the highway and i feel it starting to bounce on that side so iam thinking that the universal gets sent out of ballance and starts... Iam thinkin that thats where the bounce starts at then echos across the truck like a pervious post said and then she lets loose on the highway (or in my case the white mud).
I took it back to get an aliment and they said that they only have factor specs to deal with so i have to get it done where some dealer puts them in and get it aliined properly.. its going into dodge today to get the universal fixed and i will get them to aline it there they put in lifts so they should be able to do it..

 

Mine is going back to the dealer for the same reasons "DEATH WOBBLE". They said that it was the ball joints and the streering stabalizer. I should have it fixed on Monday evening.

 

Good luck, thats what i thought it was at first..... Nope!

 

Mine was that way when I got home.. Ball joints were shot at 500 miles!!1 That fixed it the first time!!

 

I think i got the Problem figured out Rotated the tires today and Hit every bump on the way home today i could see 110 120 140km and i got nothing......even where it was doing it before on the freeway here it wasn't doing it... I think iam gonna invest in some new tires..!

Anyone Run Dick Cepek tires 35 12.5 17 AT's?? and how are they for milagae and ware?

 

Sorry to say, but your SkyCrapper shocks are mostly a key player in the cause of your Death Wobble.

When I had stock shocks and all stock front end, I had DW a couple times. There was an expansion joint on a local freeway that would cause it EVERY time.

After I levelled the truck and installed Bilstein shocks, it left and never came back, even once. I also installed a DT track bar at the same time.

Lift kits are often prone to DW, because the parts have to be proportionally much stronger, and most lift kits I've seen are actually pretty cheap.

So start with the track bar-- make sure it's a beefy piece like Thuren's. then check your shocks.

A Steering stabilizer actually has little role to play in DW. DW is caused by oscillations through the suspension and steering structure.

With the 5-link setup we have with coil springs and a solid axle, you'll notice that the axle cannot cycle vertically without also cycling laterally because of the radius of the track bar. When the truck is lifted, the increased angle of the track bar only makes the lateral movement worse.

So where is the damping that can stop the oscillation? Your shock absorbers are the only real damping in the mix.

Now, as the suspension cycles, the steering will change too. That is, assuming the Pitman arm doesn't move, the the steering linkage would have to change length to follow the axle's movement. Obviously it can't, so as the axle goes up, the effect is the same as the steering being turned to the right, and vice versa.

Another thing I think plays into this is that DW is really a form of "spring wrap." What? With coil springs? YES! Even though there are two trailing arms on each side of the axle, there's still a great deal room for the axle to "shift" back and forth in a way that bends the the spring instead of compressing it.

That where something like the DT radius arms would help. The caster curve with a design like this is predictable, and a lot less prone to DW imo.

There are a lof things that go into DW-- and it can be a really frustating nightmare to track it down. Just check EVERYTHING, and remember that even the littlest thing can be important-- and sometimes it's only the result of multiple little things adding up.

Put new tires in front and make sure they are balanced. Before you spend $ rebuilding your truck. My experience lifting trucks that do what you are talking about has been fixed by good tires that were balanced in the front.
