Just had to reply. Quality and service is going to zero. When you buy something don't expect a warranty. If you get good service it us usually just luck. I have had 2 fords fail in warranty,, dealer replaces the wrong Cougar part,, then tells me the item that failed wasn't under warranty. My daughter's ford Escort shifter broke. ( the plastic pull lever ) Dealer response,, not under warranty.


GM isn't much better. I had an engine fail at 3000 miles and it took months to get the car on the road again. We bought our first foreign car a few years ago. It is always Hello Mr.. and I get a loaner when we go for service. Granted it is a 100 mile round trip for service but this happens only once a year.
When people wake up to you must provide service they will begin to capture the market again. The problem is that if a company listens to the customer they just patronize them and do nothing else,, but most don't listen.

Just give it to Mikey he will eat anything attitude. Now I buy cars when I need transportation and price/service will be a determining factor. I bought a new corvette several years ago. The first dealer laughed when I asked about ordering one. The second got the car then the service mgr told me "we don't really care where you get your car serviced or buy the next one". To say the least I haven't returned there and if I buy another Corvette it will be somewhere else. Ok,, venting and sorry if this is OFF TOPIC

Ya'll have a nice day. Jim

 

Enough ranting - lets get this thread back on track - it's not the Warranty thread - it's a BOUNCING TRUCK thread.... the other comments - while well intended - don't fix the 'issue'....

I spent the better part of the day IMPROVING my beloved big azz F350 as I intend to drive it many miles... to that end - I've ordered the Talon Suspension System - and I worked today installing the Banks Big Hoss Bundle... tomorrow it will be driving time!

 

Ok guys, just searched this thread and I also have the same prob. 2002 F350 CC/LB 38-42 bounce. I have a firm belief after reading this thread that it might be driveshaft angle related. There is a TSB abt shutter on takeoff with longbed crewcabs. Has anyone shimmed their center bearing for takeoff shudder and has it been corilated to the "bounce"??

 

I have an EX 7.3 with no "bounce" however there are engineering max,min angles for u-joints and center bearings on shafts. Of course we know Ford would never forget the basic engineering manual and have the shaft angle incorrect. UMHHHHHHHHHH or would they. Jim

 

I tend to do the cheapest things first when troubleshooting. In this case, rotate your tires and see if the bouncing changes. If it does, your problem is tire or wheel related.

 

I believe most of us have been that route. Rotated tires checked ujoints, center bearing, etc and to no avail. Seems it is happening to mainly CC/LB trucks. My brother inlaw has an 03 and his does it also. Driveshaft angle is the only thing I haven't changed. It just may be inherent to the length of the wheelbase and driveline harmonics. Dunno.

 

Yup Guys & Gals,
What has been said by 89lxbill is absoulutely true. I have gotten access to an accelerometer reading tool used by International and most GM Dealers last week. Took my vehicle for a drive with a ride control Engineer and took photos of the Frequency reader ( which reads the first 3 dominate frequencies at any given speed you may be driving) while also marking the specific speeds which the vehicle was going.
The analysis of the photos and the driving speeds provide undeniable proof that the vibrations in our longer WB vehicles is attributed to Engine, Drive Line , Wheel and the associated Frame resonance, which will be extremely difficult to eliminate until the entire dynamics of the vehicle are changed. In the next week or so I intend to put all this information and how this conclusion can be arrived at into a report that I am taking to my dealer while insisting at the same time the FoMoCo Field engineers be come involved to at least minimize this problem with if necessary new tires and a complete check of the engine firing and a fine tune balancing of the Driveline. My vehicle did not demonstrate this contineous vibration problem until about 8000 Mi. Now 13,500 on it

Make sure to keep us all posted. I'm sure there there are a lot of owners out there who are eager to find a solution.I always thought it felt like the entire frame was flexing maybe amplifying the little things .[like an out of balance tire ,or maybe even a driveshaft with excess run-out]Great work! Hopefully Ford with resolve this with future designs as well as come up with a fix for current owners/buyers.

 

Will share Information ifpossible after I get it in the report form.

 

I had similar issue with my 2006 f250 xcab super duty. Dealer after many hours of force balancing tires, repositioning tires on wheels, varying tire pressure and two new tires, the truck is perfect. No bounce, no vibiration, no wheel shimmy, no bumpsteer. I have a new respect for my dealers shop foreman who personally spent hours to resolve the problem. I am not sure, but I think he said that he had to avoid 78 megahertz. He also told me that he just attended a class on this problem and that Ford advises to check the tire to rim fitat the bead with a feeler gauge and to follow certain proceedures to resolve this issue. I thought that they were never going to be unable find and resolve this problem, but they did. I am now very happy with my truck.

 

Do you have the long bed??

 

OK - I managed to find a way to share the info that I recorded with a Vibration Analyzer (EVA) on 12/13/2006 with a ride Engineer from International.

It is quite obvious to me after developing the completed information that the Engineers and many of the Dealers should be capable of doing the same. (EXCEPT MUCH EASIER) - FORD / GM and others have the equipment
Evidence shows that after a payment for a static balance (which made the vibration worse) and after a Dynamic Force Balance that the vehicle STILL HAS WHEEL / TIRE ISSUES. I have uploaded jpg files of the photos taken from the EVA and the charts that were developed for my truck as well as the conclusions that can be drawn from same to the Webshots address below if any are interested.

Bottom Line is that most if not all of the vibration is either from Tires and/or wheels and maybe some driveline imbalance. The Address given is set public for you guys and gals - let me know ( I'm Sure all will ) if it does not work somehow.

I have a 2006 350 super duty with 29,000 miles , when I talk around with other Ford owners and have read all the trucks that have that same problem it makes me wonder "what's up with dat ", I got the bouncy , jumpy , jitters at about 42-46 mph since about 5,000 miles , got two new front tires a while back and it stopped it for a few thousand miles but it came back , it just got out of the dealership last week and they put a new steering box, tie rod ends and steering bars , no cost to me thank godness cause it was in a wreck , it still does it just like when it went in there ,it's aggrevating especially when the speed limit is 45 ------ I have to think there is a some bigger problem with design or engineering ----recalllllll--- fishfiles

 

Excellent data. I have used the IRD Mechanist Vibration Analyzer on large machinery. Your data is right on the mark. My son has a F250 6.0 and I have a 7.3 Exc. We swapped the Alloy wheels/tires from the Excursion to the F250 and proved your data to be correct. We can't prove but theory is that the steel wheels do not hold "trueness" and deflect. This out of true with tires that might be slightly off can cause the vibration. It was amazing how smooth the F250 was with the Excursion wheels and tires.

So IMO we have confirmed your scientific data by actual in field work. Jim

 

Just had a thought. For those folks that have vibrations issues,, given a tire/wheel issue. Poll how many have the problem with factory origional steel wheels and how many with the factory cast wheel. If anyone knows how to set this in a poll it might be helpful to determine if this is wheel or tire issues. Jim
