knock/clunk when turning, silent when stationary

Hi people, just looking for some advice please before I get a proper chance to look.

 

Car is suddenly making a sort of clunky knocky noise at speeds when turning as little as half a turn, but when stationary it makes no noise at all going from lock to lock.

 

I have reisently added 4mm washers either side of the steering rack aswell as a full alignment set with my front camber from 0.5degrees to 1.5 degrees.

 

I had suspicion that it was the tyres rubbing the inner front archs, which I earlier removed and still have the noise. I have no sign of play at any speeds, no noise on speed bumps or uneven roads, it is purely from 5mph upwards at as little as quarter a turn that there is a noise.

 

Any advice or previous issues with people on here please, I'd be extremely greatful!

Clunks when maneuvering at slow speeds are often down to loose subframe or suspension component bolts, I'd start by getting the car on a ramp and torquing up all the bolts, then checking all the suspension components for play.

ok on inspection it has come to my attention the the front crossmember which bolts to the rear of the wishbones, the eccentric camber/castor adjuster on the drivers side is no longer sitting tight against the adjustment blocks. instead it has about 5mm of room which is causing the bush to move and thus knocking the eccentric against the blocks when steering. i Can have this temporarily fixed but obviously due to age the blocks have weekend and bent. so my intention is to get another crossmember, have it properly powder coated and then bolt that onto the car.

 

Has anyone got a recomendation where i would be able to find a second hand one in useable condition and at a decent price please? Hopefully sooner than later too.

 

Many Thanks in advance

Dave

Ok well issue resolved, and im scratching my head how. Ended up pulling out the castor eccentrics, straigtening up the adjuster plates a bit that were bent, checking for any play in anything. Fitting the eccentrics back, tightening up the nuts on the camber and castor eccentrics with a crack bar, and no more noise. Everything was tight but went up maybe half a turn more with the crack bar than it originally did with spanners. So maybe it was the bent sdjuster plates or maybe the camber bolts needed that fraction more tightness. Either way its fixed and im happy again :) thanks for the replies people
