Thanks. I am new to the forum!
Ok after scouring the net, and this forum I have several suggestions as to what it might be.
1. Sway Bar End Links
2. Stabalizer Bar Link (same as above??) Kit 5486AT
3. Brake Calipers ("had too much clearance. Thousands of inch; early produciton. Brackets replaced with later produciton, noise gone." from another fourm..)
4. Computer or some other "box" comes loose from the firewall. Excerpt from another post "The problem was with the firewall but it seems that the bumping problem came from another metal part that was indeed banging on the firewall. They repositioned the part and it is now quite. To access the part "metal part- as described by Serv Rep" the front cover under the windshield wipers had to be removed (but this is what the service rep told me and I take his information very lightly)."
So At least I have some things to go on to tell the mechanics.
