My new to me LJR has death wobble (I drove it home from SLC to Denver when I bought it and had no signs of DW). Here is what I know:
_I did the dry steering test and discovered the adjustable track bar bushings were shot. The track bar was one of the few parts on the jeep that was not from a brand I consider up to my standards so I replaced it with a currie adjustable track bar.
_After replacing the track bar I was back on the road at highway speeds I hit a bump again and had death wobble again. Back to the dry steering test and further inspection I noticed some of the control arm bushings were also not in great shape. Ive always wanted Savvy's fully adjustable control arm set so I bit the bullet and replaced all the control arms. The old control arms were JKS but some were not adjustable. I wanted the ability to adjust so it made sense.
_As part of my build plans I wanted to do Black Magic's Vanco big brake kit. This thing is on 35's and had stock brakes. So at the same time I installed the control arms I also installed the big brake kit. I did new spicer ball joints and timken unit bearings at the same time because I was in there. Got it aligned and back on the road and it was doing great for about a month. Highway driving felt great and the jeep overall tighten up which was nice.
_Fast Forward to this weekend I had a 160 mile round trip up to Fort collins on Saturday and the jeep did great. Before leaving I checked the torque on all my control arm bolts, and track bar bolts, all were perfect. On Sunday I did the same trip and had a pretty bad incident of Death wobble on the way up to Fort Collins . I went the rest of the way to my destination and home on city streets to avoid DW again (man was that slow haha).
At this point the jeep has:
_New Currie Track Bar
_New Savvy Adjustable Control Arms
_New Big Brake Kit
_New Front Axle U Joints (Spicer)
_New Ball Joints (Spicer)
_New Unit Bearings (Timken)
All of this was planned except the adjustable control arms so I am not sweating it too much, but I am running out of ideas. The only thing I can think of is the axle housing bushings for upper control joints. I probably should install the currie Johnny joint kit so all the control arms are johnny joints.
The steering is a Currie Currectlync System and all tie rod ends and drag link ends feel good. The only thing I noticed today was the draglink end at the pitman arm was at a severe angle, is this normal?
Any other thoughts?
