Horrible shaking on the front end from 40 mph and up...

[Kory Lee]

I have a 96' F150 4x4 extended cab. Has a 6 inch lift with 33'' tires.

Just got an alignment, ball joints replaced, tires rotated, and hubs replaced. Whenever I drive over 40mph the front end begins to shake almost out of control. I have tried all I know at my level of expertise. Looking for some help!!!!

is it all the time over 40 when wormed up and cold too?

Sounds to me like one of the tires needs balanced or replaced. You may not have noticed it when it was on the rear of the truck but now that its on the steer axle its showing up. Try rotating them back and see if it helps.

Are the weights still on the front wheels? Sometimes they fall off and will throw the balance off horribly. That could be the cause of your shaking.

Either warm or cold. I payed closer attention today and it mainly does it when I'm driving over 40 and hit a bump in the road on the right side. Could that have something to do with the brake lilne? A buddy of mine said to bleed the right side brake lines and see if that works.

I'm going to do this tomorrow and see what happens. Thanks!

Not likely. Rotate the tires.

Will do... After that I thought about trying the dynabeads. Ever heard of them?

Based on what you said, it seems like one of the things done likely caused it. The shop that did the rotation should be willing to check it out. I agree with the folks who thought it threw a weight.

I have. But for 33s its overkill. They should balance out fine if mounted right. Also keep in mind if u get water in there with the beads it can freeze and cause problems like what you are having now

I've been having the same front end issue plus a few more with my 2000 4.6 2wd. I figured the bulk of it to being my front right caliper freezing up. After replacing it (the old one was definitely shot) most of my front end issues have been resolved leaving me with just the wobble around 50 mph. The tie rods are tight & the ball joints seem otherwise sound when turning @ speed. In effort to eliminate the wobble I had my front wheels rotated & balanced. (I'm running stock sized wheels & tires so I got a good used set put on the rear) I haven't put too many miles on it since the balance but the wobble only seems to surface 1- when I hit a substantial bump around 50mph or 2- when applying a liberal amount of brakes on the highway.
As soon as I find a decent used pair I'll be switching the front tires as well & I'm sure she could use an alignment in any case. I'm wondering if you've made any more progress with your situation. Or if you've noticed any relation between your wobble & braking. -Thanks
