ok here we go i have see a few treads about this.
people complaning about a clunk when turning or on full lock
this is caused by the suspension spring cup coming looses these are originally pressed on which you hay have noticed is the reason im doing this tread as they come loose and need welding
ok not first of all you will need to check for a silver ring around the suspension strut
follow the pictures
located here
and here is it a bit closer
ok next 1 is where the cup is

ok people this is where we get technical (lol)
this is where you will see a silver ring where the cup has moved about causing the knock/clunk and where they need welding
ok now how too
first of all you need the car on axle stand or ramp either will do
remove the wheel
remove the caliper and disc
remove the bottom ball joint nut and bolt and pull out the ball joint
remove the anti roll bar nut (some dont have them)
remove the track rod end nut (from the strut)
and remove the drive shaft nut
undo the 3 13mm from the top mount
now you will have to use some spring compressors and remove the top mount nut remove the mount and spring
now you will HAVE TO REMOVE THE DAMPER because if you get it welded with out removing the damper you could face a nice explosion a guy at work found out the hard way
to get the damper out remove the big gold nut and it will slide out
ok when refitting after its been welded here
put a little engine oil in the strut where the damper goes bit of grease round the thread of the big gold nut holding the damper in and refitt every thing double check its all tight and there you go all done and no knock/clunk
if you having difficualty pm me and im happy to help
if this tread help drop me a rep
cheers steve
