Guys, I dont post much but read quite a bit.... Let me start of by saying, I like my truck, I have had it for well over a year now!
I have always noticed that the rear wend will tend to "walk" when hitting bumps, I always assumed it was b/c this was an F350 SRW and the rear end was more rigid than say a F250.
My definition of "walk"= feels as if the shocks are not holding the tire on the road over a bump, I have actually had the rear end move side to side on me while "walking".
Well, a few weeks ago I drove to Illinois to do some bowhunting, spent the week and on my way home I had cruise set on the hwy at 70 'ish. I was coming into a curve on the fwy and hit a couple bumps and the front end "walked" on me and it was a very short moment there I was having flash backs from the death wobble I used to get in a Dodge 2500 I had, key word
had 
.... Anyhow, I blew this off as I have never had the front end do this before in 30K miles or a year and a half..
Well, last week another road trip, this time in my hunting buddies 2012 F250 King ranch, it's my turn to relieve him from driving and it happened to me so I asked him about it and he said it does it quite often????
FTR, I have had a 2000 7.3 with 200+K on it and an 06' F250 for 7 years with over 100+K on it and have never had any issues like this, also I recently had the tires rotated and all pressures are correct. The only time I have ever had any issues was a Dodge 2500 truck that had major issue with the death wobble (traded it in with 16K on the odometer)...
Now, I have considered a leveling kit on this truck with a tad bit larger tire. At this time upgrading shocks would seem almost a must to me.
So, have any of you folks noticed this issue? have you found that better shocks or anything else helps with this????
Thanks in advance for your input!
