Thats right! Good luck.

 

Also in Austin... Also new to trailering and have a 2002 FX4. Mine was doing the EXACT same thing until I realized that the pin was a Class II pin and the receiver a Class III/IV. The pin diameter is completely different. That little difference prevented the ball mount from slipping in and out the extra 1/8th inch and made the difference. Maybe that is all there is to it?

 

Well, how did it do?

 

Well guys,

I welded 6 beads across the hitch and ground them down to take up the slack, changed the fuel filter, lubed the bushings, and changed the ball...One of the four did the trick. It pulls like a champ now. Thanks for all of you help, guys!!

 

Check your tongue weight and your hitch height. Are the trailers you are pulling tandem axle? With a tandem axle trailer if the hitch height is wrong it will unload one set of wheels and beat you around when you go over bumps and stuff. If the tongue is too light it will bounce the truck up and down and that could be construed as a jerking motion. The fix for that is more tongue weight or adjusting the hitch height to make everything happy. If you are using a weight distributing hitch try loosening the bars a bit to put more load on the tongue. If you can post more info on the kind of trailer (axles and such), and maybe we can narrow it down a little more.


Whoops!!!..... didn't see that last post saying you got it. My bad.

 

I am glad you fixed the problem. I noticed you said you have a locking rear end, unless you put it in you have a limited grip I mean limited slip.

 

i HAD THE SAME PROBLEM WITH MY 01 SUPERCREW. THE PROBLEM WITH MINE WAS THE TOWBAR WAS LOOSE. IT HAS ALOT OF PLAY IN THE RECEIVER. CHECK FOR EXTRA PLAY.

 

Just came across your post, I had the same problem. My problem was the springs, I know you have HD springs but you may have stressed them. I had the whole drive line either replaced or balanced. I added some Helwig HD springs and that solved the problem. What was happening was the rear end was sagging on take off and the pinion angle changed causing vibration.

 

I've had the same thing happen. It's known as "slop" in the reciever hitch. Try sway arms or ad weld and grind flat till the draw bar is snug in the reciever.

Rock on, Ford fans!!

 

Ok, a friend of mine had a similar issue.

the pin that secures your reciever hitch comes in two sizes. He was using the smaller size in a hitch that required the larger size. This left alot of "slop" in the receiver hitch and was extrememly noticable when towing.

Just a thought.

good luck!
