I had a loud thunk noise a few years back on a RRC, which is basically the same as a Defender as regards running gear, I thought it was CV, spring, changed the swivel bearings both sides and the bastard still did it. Turned out to be the front radius arm bushes rusted and worn in the arms, and would twang when on full lock sometimes. Doesn't help you much I know, but check the condition of the bushes, might be the cause if you cant find anything else.

Hello welcome check rear shocks were mount to chassis as you was towing poss could only make noise under load

I'am new to this site too, I had a situation like yours.....After investigations found the tyre was rubbing on the radius arm's on hard lock......Adjusted the steering lock/stop bolts on front hub's...... Still happens from time to time but I'am now aware of this problem.
Hope this might be of some help to you..

thanks everyone i will try them tomorrow will keep you updated :bounce:
