QuestionQUESTION: There is a distinct clunk coming from the front end of my 1985 928 when turning at low speed. I have replaced the upper control arm bushes and the steering rack support bushes. There is no visual sign of deterioration in the lower arm bushes and ball joints look/feel ok The power steering rack seems ok too The springs and shock absorbers were replaced approximate 20000 miles back Any suggestions?
ANSWER: Does the "clunk" happen when turning in both directions?
Does it also happen when backing up and making a turn in both directions?
When did the "clunk" appear with respect to mileage, after the shocks were replaced?
How many miles are on the odometer?

QUESTION: The clunk happens in both directions. It started on the right hand side (the vehicle is right hand drive) and is more noticeable from that side. It does not happen in reverse The shocks were replaced soon after I bought the car in 2002 I drive it often but usually not long distances hence only 20000 miles in nearly 6 years The noise became apparent from the rhs about 3000 miles ago and from the lhs about 1000 miles ago The odometer shows 182404 km so say 113000 miles Thanks for your help
ANSWER: 113k on a shark is not a lot of miles, however it is a lot of miles on any car and after 23 years you got to wonder what could it not be.
I have not asked, is this "clunk" a repetitive continuous clunk or a once-a-clunk ?

QUESTION: Its a once-a-clunk. I can induce it by making a downhill turn at low speed This makes me think it is somehow spring related It happens at the apex of the turn which I imagine is when the spring is in its most uncompressed state Hmmm?
AnswerOk. Let's keep this thread going.
"I imagine is when the spring is in its most uncompressed state Hmmm?"
I'd clarify that as when the suspension is uncompressed.
Advise on the following, some of which may or may not relate but on a shark with 100K miles its good to verify.
1) Steering rack mounting bushings, all four of them.
2) Inner tie rods, that is under the boots.
3) Sway bar bushings and hardware.
And by the way, what is the slowest speed to you make the "once-a-clunk" happen?
