as above 70mph today, approaching a roundabout so i lift off throttle. only to get a very violent shake from the steering wheel that slowed down with less speed. at 1st thought puncture then considerd a wheel weight came off but theyre fine...

pulled over asap checked wheel nuts are tight and ive no punctures! drove off steady and all was fine. ive since done 70mph and given it a bit of stick to provoke it again but nothing.

steering fluid is good level. cars a 93 wrx import.

any ideas? pas pump fail? or rack failure?

cheers

Did it happen under braking? warped disc? Could it be wheel bearings? but if it was it should show all the time. Tricky to say
Goodluck maybe someone else can shed some light on it for you.

 

no mate just lift off throttle not under braking.

 

possibly trackrod ends, steering rack joints. worn bushes , as said tricky to figure out,

 

I would of probley gone for driveshaft or cv joint if it wobbles in deceleration as there is no load on them at that time.

 

its fine now. coverd 20 miles.

wonder if i ran over something got stuck to the tyre?

 

very ba this morninf even at 20 mph and a nasty metal noise sounds like something is catching. i think a spring isnt seated correctly as when i turn 1-2mph full lock each way something crunching!

 

also to add this was doing it when driving not lifting off throttle this morning.

i may have fixed it. jacked up, wheel off spring rotated 1/4 turn and became ill seated. the top spring seat had been forced against the inner chasis.

removed leg, top hat off and reseated in best position (not perfect. i wish they had markers on them). just coverd 20 miles gave full lock both ways and tryed to provoke it.

at 1st a few clunks backing/turning off driveway. few more at the end of the road but for the remainder of the drive all is well. keep fingers crossed please.
