Can anyone tell me how?
The internet is rubbish.
I have more than suspected my steering rack has been dodgey for some time.

Constant Symptoms:-
Vibrations from 70mph +
Car never seems to go where you want it too,
If you shake the steering back and forth you get a nice knock.
When I start to steer in any direction I get a "BomBom" noise, sounds like a bubble going up through water or oil?

Intermitant Symptoms:-
Sometimes I can't keep the car in a straight line and it wanders. (I have been trying to blame this on the ruts that the lorrys make in the road but I've had it happen on the flatest of roads, roads that i've never had an issue with before.)
Getting lots of creeks and crunches from the front end while steering excessivley, mainly when I'm braking at the same time.
Vibrations vary, sometimes it goes away above 80mph, but I have also been clocking 120+ for it to start shaking randomly.


In general the car drives ok, the car always tracks straight and true but does give a torquesteery effect when I change gear at full throttle?

All four wheels are straight and true with new tyres on them. All balenced correctly etc.

The car has brand new inner and outer track rods along with full four wheel alighnment.

There is no play in any of the bushes or ball joints on the car.

All CV Joints are fine and well greased. All the driveshafts run straight and true.

So how to I diagnose that my steering rack is at fault before I go buy one and replace it?
Is there any tests I can do?

Cheers, Bailes.
