Mopar Lift Then Death Wobble at Low Speed "SOLVED"

[Desert Dog]

Hey for you Guys and Gals with Death Wobble with the Mopar Lift. I Thought you may be find a solution as I did for Death Wobble. I installed The Mopar 2" Lift on my 21 Sport S Max-Tow A few weeks ago and took it to my standard alignment shop to get it aligned. After I picked it up I noticed when I hit a Bump,Pot Hole,Rail Road Track, or Overpass I would experience moderate to severe Death Wobble at speeds below 45 mph. My shop said The first Alignment was within spec and wasn't the Problem. I rechecked most of the normal items, I found as potential causes on the Forum, but still Death Wobble. The last item to try was increasing the Caster, That Worked! You can see on the the Alignment setting pages I've posted, the difference on the Caster and slight toe Alignment #1 VS Alignment #2. It doesn't seem like like much of a change, but the results are a more solid feeling with no Death Wobble. I'm not saying this will work for everyone,but it worked for me.

Just thankful I didn't have to read another "my steering stabilizer solved it!" and all the comments that follow. ?

Been meaning to add a few turns to my LCAs.
I'm on 37's and the steering is already..... tough.... How is it with ~5.5º?

Drives great , much more stable and solid feeling than before. By the way, Still running stock Recalled Stabilizer. I forgot to say it’s running 35 12.50 20’s. I own a Classic car dealership and we build Early Broncos, Scouts and Jeeps. I’ve been building Jeeps for 40 Plus Years. Have had my share of Death Wobble issues.

For the 2 inch lift and 35s you can go an easy 6 deg caster. Mine is at 6.1 and it's great. I have the fixed arms that came with the kit.

How are you adjusting caster with fixed arms?
