Other Things that cause clunks in E series...
Ball joint...esp the lower as it carries most of the weight.
Loose wheel (should be obvious tho...and would be gone after the mechanic did it)
Failed tie rod or tie rod end
Loose Castor arm...rear end, bolts are loose, front end bushes are shot
Loose or failed strut. I hit a pot hole in mine once and had a clunk. the U section that attatches to the lower control arm had collapsed, and under normal load sat clear of the control arm, but as soon as it hit a bump the first movement was in the mount and a clunk ensued...i found the fault when it finally wore through the strut and the gas escaped in a rush.....and i finally pulled the wheel for a look
PS....thats one clean car....care to do mine?
