Schu Posted October 26, 2016 Share Posted October 26, 2016 Id like to take a look at that printout from the aligment shop... if you have bad toe angles you can have one side of the vehicle fighting the other side as you try and track in a straightline. One other thing Id like to ask... is the vibration coming thru the steering wheel or is it coming from the chassis (thru your seat)? Quote Link to comment Share on other sites More sharing options...
BEC Posted October 26, 2016 Share Posted October 26, 2016 Do a Google search on "2004 Ford F150 Vibration". I have one I bought new. Never did get that all figured out. Ford likes to say just inherent to the vehicle. Quote Link to comment Share on other sites More sharing options...
Woofers and Tweeters Posted October 26, 2016 Share Posted October 26, 2016 Typically: If it vibrates side to side when braking (feel it in the steering wheel) then it's the front, while if it pulses (seat of the pants) its the rear, typically if it happens at only one speed without the brakes applied, then the brakes aren't the culprit , typically If it's shaking dentures out, then it sounds like it's in the front. You might take a minute to rotate the tires front to rear to see if it moves If it's a brake dragging, then pop it in neutral will feel like the brakes are applied The Hat and Rotor rear brakes / parking brake that Carl mentioned can be a problem too (we have a test vehicle that acts up when it wants to) When you're getting the vibration, does it change when the gears are changed?

When I go around a slight curve at high speed my steering wheel wobbles a bit, but the violent vibration at 48 mph shakes the entire truck up and down. It just doesn't always do it, kind of intermittent. The high speed vibration is pretty constant though. Quote Link to comment Share on other sites More sharing options...

But, they're balanced and a road force balancer was even used, which ought to rule out any being out of round. Not sure what to do or what it means. 11 hours ago, Weber said: When you're getting the vibration, does it change when the gears are changed? Not that I'm aware but I'll try to pay attention. The high speed slight vibration is definitely while in overdrive and occurs at any speed over 65. 48 mph is right on the edge though so that worries me now that I think about it.

Clean them and see if you can adjust them a little looser. 1 Quote Link to comment Share on other sites More sharing options...

There is a funny little drum brake that is exclusively for the parking brake. If you were not looking for it you would probably miss it. +++ And this is a manual transmission? The automatic trans can definitely cause the vibration you are describing. Quote Link to comment Share on other sites More sharing options...

USNRET Posted October 26, 2016 Share Posted October 26, 2016 I used to drive a large flat bed truck that would almost rip the steering wheel out of your hands as it turned back and forth violently after hitting a bump; that was ball joints. I saw earlier that this isn't your problem. So I am really just wasting bits and bytes and your time 1 Quote Link to comment Share on other sites More sharing options...

Crap, I forgot, you're exactly right. It's a disc but the middle is big, like a mini drum. When I put new rotors on in the spring this thing was locked up, had to get a pipe and put on the inside of the rotors then beat on it with a hammer from underneath the truck.

Is that the exact moment the problem started? I'm not sure. I rotated them right before I went on vacation. I got to the smokies and some vibration was there but it wasn't too bad, just rough more than anything. Something happened in the smokies though because the 7 hour trip home was miserable, it got worse while I was there. When I got home I had them road force balanced but it's still not right.

Drove it on the interstate home for some stupid reason, and the shackles flexed so bad that I had an involuntary lane change, then got a good dose of "death wobble" right there in the middle of the interstate after I fought it back in my lane. Had to find the nearest exit and drive 20 mph home via backroads. Quote Link to comment Share on other sites More sharing options...
