Please Help!!! After long time of waiting I installed a 4 inches Rancho lift kit RS6579B with a dual steering stabilizer kit RS98511 and a set of 37" M/T. Now to my horror my truck is experiencing death wobbling.
It scares the hell out of me as I always have my 18 months old kid with me.
How can I solve this problem??
Please Help!!!

Did you get the truck aligned after the lift kit installation?

Alignment and did it come with a drop pitman arm and a trac bar relocation bracket

Thanks for your soon replay. Yes I had aligned as per installation kit document. Also, yes, this kit came with drop pitman arm and the track bar relocation bracket.
This weekend I will check again alignment and quality of bushings.

Make sure all bolts are torqued to required specs... and check the psi in the tires too!

Thanks Mark! I will! I'm just curious... I've seen several videos at youtube showing this problem on our heavy duty RAMs... but what's exactly the root cause?? Is it true that is specificaly related to de trac bar being loose for unpropper torque or worn busshings??

I will let you know how I come out of this issue

Very Best Regards to All

I had the death wobble problem early in my ownership of my 03 2500 had it to the dealer and several alinement shops all said no fault found. there favourite three words. Then i was told by a friend to call a Dodge dealer in Calgary alberta they deal a lot in HD trucks. Called and was told to adjust my caster out as far as possible, did that and it solved my problem ,Caster is how far forward yourfront wheels are ahead of your axel have not had the problem since 06 . Not saying thats your problem but it solved things for me

Forgot about that one I fix cars and trucks all day too

You are correct caster is the wheels forward of the axle center line upfront and with to little caster the truck will be very bump steer and wobble prone too much and it will just put added steering pressure on the linkage have them set it at about 3.7 degrees on left and 4.2 degrees right if possible and set the front toe to .5-.10 positive on both front wheels and you should be good provided everything else is tight and good

My wife's 2003 6" lift is at
3.7 l and 4.4 r caster
0.2 l and 0.0 r camber ( only adjustable with Aftermarket kit)
.10 l and .10 r toe
