Steering response - lots of things to check
MParrott,
Basically, if I understand all the posts I've read, plus results I have seen with the mods I've tried, there are a number of things to check before you might find the problem(s).
I have both the DSS steering shaft stabilizer and the track bar bracket. The DSS helped bit, but my truck still exhibited some wandering. The DSS helped some, but didn't completely clear up the problem. I went for the track bar bracket, with the 3rd generation track bar, but that didn't seem to make much difference on my truck. I didn't mind the cost for the track bar upgrade, since it will keep me from worrying about a loose ball joint on the frame end of the original.
I also replaced ball joints (they were worn pretty badly), and I'm going to replace the tie rod ends as well. Future plans will get me a new intermediate shaft, if the looseness and wandering is still present. Ultimately, I'll look at a new steering box, if all else doesn't get me a tight-steering front end. Problems in the steering gear can also be partially alleviated with the preload adjustment and over-center adjustment, assuming you don't have worn bearings on the sector shaft. If they're not worn, the DSS should help prevent wear in the steering gearbox.
You should look at all these components, checking for wear on any. Hopefully, you'll find culprits among some of them which may help with replacements. From my research, all of these can contribute to wandering or poor steering response in the front end of the heavy Dodge trucks. I'm still in the middle of my attempts, but hopefully I'll get there someday. It seems to be a prevalent complaint about these trucks on the TDR.
Good luck with your search,
John
