Old dog, new tricks
Once again, the new guy needs advice! Truck is a 2002 F250 SD, 7.3 Powerstroke, ZF-s6 trans.
Problem is a serious one regarding stability. I have had several instances, most often in a slight right-hand turn at speeds from 30 to 60 MPH, where driving across a slight depression in the road (pothole, manhole, etc.) sends the truck into what can only be described as an "oscillation". It shakes like a leaf in the wind, and feels like the whole damn thing is going to disintegrate! It doesn't seem to be all that noticeable in the steering wheel, as I still have control. After slowing to a speed below 25 MPH or so, it stabilizes and I can go my merry way (with quite a load in my shorts, to say the least!). It feels more like the entire suspension is oscillating, rather than just the front end/steering gear. Kind of a 'diagonal' or 'corner-to-corner', sideways shake.
I replaced the shocks (they were toast, anyway) but the problem still rears its ugly head. Trust me, it's a panic situation! Other vehicles near me scramble to get the hell out of my way!
What can cause this type of malfunction? Where do I look first? What can I inspect, and how do I go about that? My nerves are shot to the point where I do slaloms around manholes...and that don't look good to the cops!
As always, the advice received here is much appreciated. I'm still learning new tricks...
Cheers!
Dave
