    i have a 90 f 250 4x4 with the 7.3 diesel.the problem is in the front end somewhere i just dont understand . i have inspected everything ,all the tie rod ends , ball joints,bearings etc everything is tight an solid i did notice about an 1/8 inch play in the pitman arm itself not in the shaft . would that cause this shake in the truck .its getting to the point that i hate driving it . what else should i look for in the front end to eliminate this shake in the front end please let me know asap thanks

    check tires maybe got one thats out of balance or got the plys separating. or even out off round. fords are good for havent problems if you got a agressive tread style.

    That pitman arm isn't helping matters any, that eighth inch gets multiplied by the steering geometry. I don't remember if that truck has a steering stabilizer (looks like a shock absorber connected to tie rod), that may need replaced. My F-350 acted the same way without it in place.

    No, this axle doesn't have those bushings, the axle halves are bolted to leaf springs in the conventional manner.

    Where exactly is the play in the pitman arm, you say not the shaft, is it in the knuckle joint?

    hey pelican thanks man an that play is in the pitman arm where it connects to the sector shaft under the steering box . the arm itself has just a slight bit of play in the arm not the shaft cause when i move the arm the shaft doesnt move!!let me know what you think ok thanks

    I think your talking about the spline where it attaches to the steering shaft. This could be the source of your problem. If you can't get it to tighten by tightening the bolt, try a new bolt. If that doesn't work, you may need a new pitman arm. Let's hope it's not the shaft spline that's worn, this would be a major repair and $$$

    Some fords have a what I would call a stablizer bar of sorts. It bolts to the top of the axle and the other end bolts to the frame. When the rubber bushings go in this bar my truck would shake like crazy at the same speed range your descibing.

    Are the front tires cupping? run your hand down the tread and you'll feel low and high spots. You can usually see them too. If they are there is your problem. I have two fords and one had the tires cupped and did the same thing. the other had a bad stabilizer. Let us know how you make out.

    The F350's used a little short track bar to keep the front diff in line,and when it goes,you get the shake.

    On your F250,the tires will most likely fix your problem.Bad shocks can also cause it as well.

    Take it to someone who knows Ford TTB's,and how to align them.Most places will just set toe and that's it.

    Spring sag,and bent TTB's will cause the camber to be way out causing the tire wear.You will need adjusting sleeves for the upper ball joints to adjust it.If the left side camber is way out,look for cracking of the axle beam,just outboard of the diff assy.If it's cracked,you will have to replace it.

    Could be something other than front end. I recently had bad shake in my F-350 between 30-40. On highway, plowing at low speeds, it was fine. It turned ot to be the rear U-joint for me. Might want to check driveline.

    UPDATE!!!!!

    to all the guys that put there 2 cents in thanks a whole bunch!!anyways to tell you all the details i bought some new tires an had them put on today .the old tires were in rough shape causing some of the problems . the real problems were in the front rims , the drivers side was a little out of round the passengers side was really bad .the guy said it would take 9.5 onces of weights to balance the tire on the passengers side. so i took the front rims an swapped with the back that were in good shape .anyways i am gonna get new rims all the way around , any suggestions!! after i had the tires put on ,boy did she ride nice !! couldnt believe the ride it was like nite an day difference.so tommorrow i am taking it to have a good alignment done on it an i am gonna put on some new shocks ,also would like suggestions on the shocks .i was gonna use some rancho rs 5000's on the truck but i dont know if thats a good choice .by the way i pumped the airbags up today an boy did it make the front end look an feel alot tighter , they are a nice option when the plow is on !! i love the way my truck rides nowan cant wait til i get another event so i can try out the new tires. again,thanks so much for everyone that gave me some imput an helped me get this ol'ford straightened out ,sincerely george
