recently I posted about having my E4OD in a 92 F250 tranny hunting in OD with the rpm fluctuating from 1700 rpm to @1900 rpm. I drove the truck like this for maybe 50miles at most as I had to get it home. It was suggested to replace the neutral safety switch. I did, and the problem went away immediately. I then drove it for about 2 weeks without any problems ( @ 300 miles). Recently, it developed a shake that rattles the whole truck. I mean a tremendous front end wobble/shake that makes the truck feel like it will just fall apart. This just happened all of a sudden 1 day as I was driving on the highway. I thought a wheel was about to fall off. As I slowed down to @ 25 mph the shake went away. Now if I drive the truck past 30 mph the shake returns in various stages of severity, but sometimes it feels like the wheels will just come off. I can open the windows and see the front wheel actualy wobbling and shaking all over the place. I heard that bad clutch disks in a torque converter will cause a front end shake, but will this actually cause the front wheels to wobble also? This truck has a strange front end that does not have a stabilizer bar. The tie rods are the only thing that keep the front wheels pointes straight. Actually if I go backwards the wheels will slant at an angle as there is nothing to keep them staight. It looks like the truck has a radical camber adjustment, but only going backwards. I have rebuilt the front end @ 10k miles ego. All new ball joints, tie rods, tie rod ends, etc..

Has anyone experienced this type of condition before? I am trying to determine if I have a front end problem or a torque converter problem. Thanks.

 

I needing help with the same thing.Thats why iam on here tonight to get some info.I have a 78 f150 4x4 with new 4inch suspension lift.My problem is when your driveing about 50-and hit a small bump in the road the front drive side wheel starts wobbling and it will scare the hell out of you like you said the truck falling apart,i look out the window today and could see the tire wobbling in and out bad.The only thing i could thinkn of that i have not replaced on the front in of this truck of mine is tie rod ends,i have new shocks coil springs bushing,i really think it just tie rods but iam looking for the same info your our..

 

My problem in this particular case turned out to be the green slime I used to patch that tire. The green slime hardened into a 10oz ball and would cause the unballanced tire. As the speed built up the shaking would just build.
