'06 F250 new tires now suspension issues?
I am in need of some advise about suspension and drivability.
I am driving a '06 F250 CC Lariat, LWB, 6.0 PS, 4x4, all stock, 114.000mls.
Here is the story:
The original Goodyear Wrangler ATS (275/65-20) were worn and I got a set of Firestone Destination AT LTS (same size). These worked
fine on an older Chevy I owned years ago.
Since I got these tires on the truck the backend feels kinda squirrly, weaving around way more then usual when I move the steering
wheel around a few time, at speeds greater than 35mph. I went back to Tiresplus and they checked the alignment again, all bushings,
struts, axles and couldnt find anything worn or loose. Test drove it again and it was still doing it. Then they said it might be the
tires. They ordered Bridgestone Dueller Revo2 and put them on the rear axle (as a test). That didn not change a thing.
So they swapped front and rear which made it worse. Now I am back on all Firestone. They checked the alignment again. Then replaced
the steering damper. Still not any better. The store manager and a teck both agreed that it rolls more than it should and feels
weird, but they seem to think it is the front axle.
I stopped by a shop in town and the tech test drove it and agrees is feels different. He suggested to replace the shocks due to high
milage. He also said that new tires may have softer side walls and that could result in a squirrly (rear end) feeling.
Again for two days the tire store has been working on it and has no idea (said the store manager) what's wrong. I offered to replace
the shocks. I put some Bilstein Shocks on it. Rides better but still has a feeling like the backend is loose.
Neither store can seem to find any worn bushings, struts or anything that may cause this. It has never done that with the original
Wranglers. Could it be that this truch is that picky and really wants the Wranglers??
Any advice, pointers, help or suggestions are appreciated. Maybe there is someone out there that had the same problem, hopefully a
Thanks in advance
