So, flat springs with newish shocks and a sway bar probably hep keep it more stable at highway speed. How much of a load have you had on it while running highway speed? These guys were loaded down for a week’s worth of camping, which could have accentuated the issue.(?)
yeah, that could make a big difference.
most load I’ve ever had in the 74 is driver and passenger. I’m not even carrying a spare (yet). Still waiting for
@4x4labs to make the bumpers.
As for “highway speed”, I don’t think it’s been over 70mph while I’ve owned it. The 33s were date coded 2008, and I didn’t know what amount of dry rot might be present. With lifted, I didn’t want to blow a tire, so I never pushed it.
It has 35s and 4.88s now, so the effective gear ratio is about 10% shorter, so it’s a bit easier to get out of the left-hand lane. Overall, I think it tracks really straight for a lifted truck. It’s not “80 straight”, but it doesn’t hassle me driving the 10 miles between work and home.
I have driven trucks that require constant wheel correction and they’re a PITA.
A wander could be a number of things: worn leaf spring bushing(s), broken or loose leaf(s), failed shock)s), loose wheel bearing(s), rear axle alignment or rear pinion angle. These last two especially if accompanied by a bit of “torque steer”.
Any time the spring moves, the effective length of that spring changes, and this can cause changes in caster. Could be that someone’s lift without a cut-n-turn or with an incorrect cut-n-turn is the culprit. Could be shackle length, since a flat spring will decrease in overall length in both compression and extension.
sorry for my part of the hijack here.
