Default Steering Wheel shakes when braking between 60 to 45

hi gents,

I writing you again from the netherlands, so please be sorry for my bad english.

I have a really really big problem with my 2003er quad cab 4,7.
This problem is really pain in the ***.

First i try to explain my problem.

When i start braking from 60 to 45 my steering wheel will start shaking.
Really hard shaking.

The following parts i have allready changed:

front and rear rotors and pads.
Rotors and pads are from EBC
Tie rods
Axle Bearing and Hub Assembly (front)
brake fluid

I have also tried different tires with wheels (17 and 22 inch), both are new and new ballanced.

I'm really ****ed up about this.

Please help.

greetings Thomas

2 questions.
When were the rotors changed?.. meaning how many miles yoo got on them?
What kind of shape are your steering rack bushings in?

I had this problem since i bought this truck.
So i had also steering shakes with the old brakes.

The new ECB rotors and pads are now in the truck since 6000miles

I found the next broken part.

Please see the picture:

That would just cause "loosness" in your steering and wouldn't cause shimmy I wouldn't think since that would be AFTER the source problem.
Sounds like your brakes aren't the issue. i would look into your Steering rack bushings because if they are worn out and dried up, your rack can and will move around when you brake hard causing "shake". if that's not the issue then you may need a whole new rack altogether.
There are only a few things that can cause your shaking.
Warped Rotors....generally shake the brake pedal
Worn Tie-rods..shakes the steering
Severely worn Balljoints(but you'd have to be an idiot for them to get THAT bad as they would be clunking long before)
Worn out Rack bushings(there are only 2 i believe) shakes steering wheel
screwed up alignment but that would cause a few other issues as well.

Thanks for your help,

Where can i find the Steering rack bushings.

I have made a quick test.

I have turn on the engine.
And turn fast the steering wheel from left to right.
When i made this, my friend can feel a jerking on the wheels.
I think the steering is the problem.
But how can i check this?
Or do i have to replace the complete Rack and Pinion Unit?
