I bought a Roadtrek 170P with 185K. It came with a new engine, but had very sloppy steering and, as I found out later, "death wobble." The wobble showed up on a road where they only re-paved the surface to the white line on the right side. I caught the edge and the steering wheel went nuts, left to right several times, and for a while -- I was out of control.
The tire shops I went to had no idea where to start. One wanted $354 to repack the wheel bearings and THEN they would start diagnosing the problem. So I went elsewhere, and they told me the wheel bearings were fine, but wanted $1250 to replace the ball joints. And that still wouldn't fix the problem, as I found out.
The solution I found online. Death wobble is a symptom of a loose power steering box, and this guy in Michigan has a very clever fix for $120 (+$20 shipping):
Dodge Ram Steering Gear Box Stabilizer
It's a bracket and bearing that collars a special sleeved nut that goes in place of your stock pitman arm nut. The bearing is held in a bracket that's mounted on two existing studs on the chassis. It's about 20 minutes to install and it made a BIG difference. I could tell within 50 feet how much tighter the steering was.
This is a good idea for any 1994-2008 Dodge van or 1994-2018 Dodge truck, even if your steering box isn't loose; it will prevent your steering box from wearing out and getting sloppy.
