In reading this thread from the beginning, it is a little disheartening to think of all the nice Jeeps people sold or traded in because they were afraid of them. All for an issue that can be solved. To be blunt, I never heard of DW until I got back into Jeeps last year, and then it seemed as if the issue was limited to Jeeps. Possibly because the Jeep community is more involved with their vehicles, but definitely any vehicle with coil springs and a solid axle is subject to this.
I think some may also have miss understood what DW really is, but they have heard the term and they encounter vibration from an out of balance tire and ergo - DW.
For anyone who has gotten this far and has not dumped their Jeep for pennies on the dollar to get away from it - other makes encounter it too, and it is not terminal to the Jeep. Frame rust is a bigger threat than DW, but make no mistake DW can be and must be fixed. It is not a design flaw, it is a maintenance problem.
There are a lot of moving parts under the front of our beloved Jeep that looks very complex compared to the earlier CJs and YJs with leaf springs. But it is a better suspension. I remember the first time I saw it under a Dodge 2500 4X4 I bought new and it looked confusing to me and it was not until I watched some of these videos that I fully understood the system. I mean the CJs and YJs didn't have control arms, what do they do? Who ever heard of a track bar? Certainly not on a CJ or YJ. But upset the hard fixed u-bolt connection between a CJ/YJ solid axle and the leaf springs and it can have DW as well.
If you catch the problem early, you are only replacing bushings and maybe ball joints but let it go on long enough it can damage major components. The first YT video is about an F250 and caster. I like the analogy the video uses of the vibrating front wheel of a WalMart shopping cart for we have all experienced or seen on that goes down the isle with the front wheel vibrating back and forth. It is caused by caster.
The second video is of a Dodge 2500 (Hemi) which has basically the same front suspension design as does the F250 and our Jeep (both the trucks are heavier of course). The Dodge has almost 200,000 miles on it and during the inspection every bushing and ball joint is about shot. In fact when he wiggles the track bar, a part falls down.
The last link is to an in depth explanation of what is and is not DW, and had an excellent diagram and a two part video of the inspection and diagnosis of the front end problems of a Jeep.
Lastly, if you are not going to fix the issue your self, I would not recommend the typical auto repair shop and maybe not even most dealers. I would instead take it to a good tire shop. Tires and our front end suspensions are related. If the shop does a good amount of commercial work, that is even better for they get to see a lot of high mileage vehicles. I had my tires rotated last year and aligned, and they caught an early caster problem on my stock Rubicon with 117,000 miles.
