Its really hard to turn the the wheels when stopped and when I'm going down the highway its hard to keep it going straight. The wheel seems slow to react so I end up going side to side quite a bit.
Hey travisej, been there done that, ran 33 up 37" tall tires on my 2005 3500 4x4, had issues same as others even those running OEM height tires. Here are a few things to check, believe me, I've done lots of suspension work:
- center link (tie rod like joint off the pitman arm) check for worn joint...worn center link will cause the wheels to "wonder" making it "hard to keep it going straight"
- track bar check for play at both ends, check this by having someone turn steering wheel full left and right while you look for play at the track bar ends. This will also cause the truck to wonder at highway speeds as you'd encountered.
- check other tie rod ends for excessive play
- lastly as suggested, steering box maybe worn/contaminated fluid, hard steering suggests this.
steering box is difficult task to R&R, flushing fluid etc. not a back yard job unless you have the tools, buckets to do a flush and not to mention a real pain in the rear to get at.
ps. don't let the remark of Dodge fronts ends are all bad, can show you a pile of other manufacturers' "notorious front ends".
