I had a very similar annoying problem and it ended up being the steering rack. And let me tell you that was a pig of a job to do with the engine in and no one to help me. But it fixed the knocking.

I read your first post about a week ago and I still come back to the same thing I thought then.

 

I know you've done the steering rack, but a number of things suggest to me it may still be the rack. It is usually one of the knock things that can't be seen and also given that it went away for a while after changing it.

 

Some racks are better than others and I've heard reports here of new racks lasting considerably less than a year.

 

Jack up the LH side, grab the wheel at 9 and 3 o'clock, rock it back and forth while looking at the rack if you see the inner moving relative to the outer, than that'll be it.

 

Still got your old rack?  Overhaul it, if you find it is the rack.

What about shocks? are the rubber inserts good condition. Try going around the block only with them disconnected.

I'm going left field here as it sounds as though you've tried everything else.

Is it your washer bottle hitting the bulkhead? I had a knocking that I couldn't trace and then discovered that an almoast empty plastic bottle can make an unfeasibly loud amount of noise.

[nelo36]

Hi Guys

thanks for the replies shocks are new KYB gas from minispares

new rack also from them fitted fine also rechecked the u bolts after few weeks all tight

washer bottle is on inner wing and full

 

keep the suggestions coming

i have replaced the from sub mounts with steel and rubber ones but there seems to be a bit of a gap between the subframe lower front and the lower shell and the mount looks awkwardly

angled could this be it ? if so how would i reduce the gap between sub frame and body shell ?

 

thanks

lee :)

Found the knock at the back

rear cotton real holding the exhaust had sheered replaced and all the back is ok

just the front to sort out now
