Knocking noise from front end of 75estate.

Hi all
I've got a knocking noise coming from the front of my car when going over bumps etc. it is subtle, but noticeable
When parked up I can rock the offside wheel left to right and hear a knock whereas I can't with the near side if this is any indication?
TIA

could be track rod end, bottom ball joint, lower wishbone rear bush or ARB drop link...

Ta, if it helps I took the wheel off, grabbed the disc on the left hand side tried rocking it, no noise, grab the caliper and do same, get the knocking...

If you can roll the wheel back and forward a little without the car moving then this is usually an indication that the lower arm rear bush is very poorly .
Just done mine !

I'll try that in a bit, is that the bush with the two bolts in mounted to the subframe? The suspension arm slots into?

if you can get your hand on the bush and roll the wheel you should be able to feel the movement between the two

swap the bush insets for polly bushes, makes it MUCH easier to reassemble as there is no torsion in the bush to overcome when bolting it back together

Thanks, tried that too but couldn't really notice much, bugging me now. I went to start replacing drop links as it looked easy enough, top bolt just wouldn't budge for love nor money...I feel like heating it up and cooling would have been only way but don't have a blowtorch

it'll go into garage and get them to do it come mot time...failed.
