E 46 sloopy handling

[BM POWER PLANT]

My E 46 320 facelift feels as if i am driving through the mud on an un even road or bumpy road, its as if it does not have grip,it wanders all over the road at high speeds and under heavy breaking,it pulls either left or right,i have replaced Front control arms,FCA bushings,stabilizers,engine mountings, front shocks,front shock mountings to new tires and lastly the steering rack but the problem still persists,dont knw wht to do any more.The handling problem started after i heavily breaked on an uneven road and ever since the steering is slugish.The wheels do not have play at 3 & 9 o clock when the steering has been locked.
No more joy from the car,um better of with a chevy impala 1989....pleeeeease help

Have a look at the tyres, I had a similar issue - My tyre-tread profile was completely flat (like a perfect cylinder), this made her move around as if she was a 4x4 stuck in ruts !!
Are they standard set?

[jimmythepie]

whats the tyre width,if well wide they can wander all over

the tyres are a brand new set,the old ones that i thought were problematic i gave them to a friend with the same E 46 and it rides very superb,been driving the car for 4 years,i have been stuck with the problem for about 3 months now,i have parked the car as its a pain to drive it,even at about 13 miles/hour going over a bumpy road,you can feel the steering pulling to either left or right as if you were not in control of the car,it literally turns the steering on its own,its like driving a car with the front wheels slightly suspended in the air,before this problem it was like a magnet on the road,i used to do 120 m/h on a sharp curve with no fear,but now my maximum is 75 m/h, i have heard of the steering flex coupling,do u think it will make any change.....

Have you checked the alignment, toe-in/out and front cambers ??

[BM POWER PLANT]

will double check at the suspension clinic and give feedback

[Lord Vader]

You never mentioned of you checked ball joints or tie rod ends. Worn ball joints canc aide an effect known as bump steer. What that is, is the car will feel like its swaying or in a rut when you go over bumps or dips in the road. Two biggest things I look at are ball joints and tie rods. When ever you replace any suspension or steering component you need an alignment. If you have not gotten an alignment then it's likely that that is an issue as well.

Also check wheel bearings.
