Car Forum / Ford / Ford Trucks / April 2006Hard to drive F250
A good friend has a 2005 Crew Cab F250 4x4 with the Camper Package. He constantly complains that the truck is very difficult to drive on the highway. It is very nervous and has very little self centering action. He has had the front suspension checked by two Ford dealers, an alignment shops, and an independent mechanics. No one can find anything wrong. The technician at the alignment shop did agree that the truck was squirrelly but couldn't find anything wrong. It already has a steering damper. Anyone have any suggestions? Ed > A good friend has a 2005 Crew Cab F250 4x4 with the Camper Package.

Tires have been rotated, pressure adjusted etc., etc. He has driven a similar truck with the same tires and it is completely different. I am suspicious of the Camper Package Springs. He does not actually have a camper installed, and mostly drives the truck around lightly loaded. Ed > Tires were my first guess but it has always been squirrelly.

Over inflated "for the load" tires can result in a squirrelly handling vehicle. Whitelightning >> Tires were my first guess but it has always been squirrelly.

Also, I have never seen "squirrly handle from over inflated tires that were properly sized for vehicle but I habe seen it from under inflated ones. ----------------- The SnoMan www.thesnoman.com > A good friend has a 2005 Crew Cab F250 4x4 with the Camper Package.

If the rear axle is out of alignment the truck will dogleg down the road. Stephen N. The Front end of my 2006 F250 4wd FX4 package Shakes so bad when you hit a pothole at 70mph the front end shakes as if the truck is coming apart. The truck is completely stock tires at the right pressure. I have talked to others I have run come across with the same model and they have the same problem. It seems to be a design issue.

May be completely different than this case, but overall sounds the same with the control issues. I dropped the tire pressure from 60 lbs to the recommended 45 front and 55 rear (D load tires) and the problem is gone - I had always kept them hard no matter what I was doing - my mistake I guess.... Good luck... >A good friend has a 2005 Crew Cab F250 4x4 with the Camper Package.

Your mistake correction is costing you a little MPG too. The reason it helped your truck is because the increased rolling resistance cause by reduced air pressures changed the effective alignment of front end. If it is properly aligned, it will not be so sensitive to tire pressure. ----------------- The SnoMan www.thesnoman.com That's a good tidbit to know - at 12.9 MPG average I can use every little bit I can get. Thanks. / >>I dropped the tire pressure from 60 lbs to the recommended 45 front and 55 >>rear (D load tires) and the problem is gone - I had always kept them hard [quoted text clipped - 8 lines] > The SnoMan > www.thesnoman.com >That's a good tidbit to know - at 12.9 MPG average I can use every little >bit I can get. Yes tire pressure, size and tread design can have a noticeable effect on MPG. you will get best MPG with smooth stock type tires at or near max rated pressure. (it will not help the ride comfort thought at times) ----------------- The SnoMan www.thesnoman.com |
