nissan serena front end
 

Hi all, i became a member today as i'm having trouble with my 97 serena, every time i go over a bump i get this knocking sound from the front end, i don't really know much about these vehicles and i'm not really up for selling a kidney to pay an extortionate garage bill (£10 parts-£200 labour)!! which seems to be the norm at most garages by me. What components should i check? are there any parts notorious for this problem?.Any help would be much appreciated as i'd like to do the work myself if possible. Cheers in advance, [8D]...Phats...[8D]
