Well Bro, it was the sound of steering tie rod end as also mentioned by you....the theory of suspension delicacy is not as true since the tie rok ends and rak ends are a part of steering and not suspension....suspension is made up of caste iron and have no flexibility in them the ball joints for instance...
as far as your problem is concerned......it mite be of many reasons.....some to mention off them are..
1. hitting of ur car in to digs unknowingly.....
2. some time even parking your car in a slope.....
3. sharp cutting....
4. jerking
etc.
u mite be avoiding all of these but at tyms these can't be avoided as well....and mite be a source for the damage u explained..
