EP3 front knocking under load

[doungtrinh]

Hi Guys,

Just after some help, Got an EP3 making some front knocks when turning..

To explain further.. when you move from a stop the front end knocks alot, when your turning it also makes a bit of a knock and when your moving along sometimes the steering wheel shoots to 1 side aswell.
The noise isnt continuous if your going slow its like knock... silence.. knock.. silence if your going fast at like 60 it all sounds rather fine no knock..

* We had the both Axels rebuilt but the issue only slightly fixed itself up,
* We also inspected the wheel bushes and they seem fine.
* I took it to a wheel alignment place who said everything looks okay, but 1 wheel has 2 degree caster difference.
* We had both caster bushes in the Control Arm replaced.
* We then took the axels to another shop for a 2nd inspection, they said they looked to be possibly binding so they rebuilt them again.

After all this we still really arent any closer and the front has a knock to it still from a standing still position.

* If on a hoist going lock to lock it is fine, its only under load that we begin to notice the knocking.

Not to familiar with the EP3, but im kind of confused to what we could do next?

My guess is Steering Rack bushes? or possibly the diff? or steering rack?

Any help would be greatly appreciated.
