Costelles

Changed front and rear ARB bushes today with genuine Porsche and the knocking seems to have gone …i tried getting the drop links off but it started to get too cold and I was ducking between showers..that’s for another day.

Im now thinking did I really need to replace the coffin arms and tuning forks maybe or maybe not but it’s good to do anyway as part of a gradual suspension refresh 

Thanks all for the help 

That’s a good shout..i’m going to do drop links and ARB next

No I didn’t as i did the same on my last 996 and it solved the issue 

Looks like drop links next, do they have a habit of seizing bolts ?

Thanks PMd you

Thanks for the response, i’ll take the wheels off and re torque all the bolts using the jack to create load

Do you have the correct torque values for all the bolts?

PS..changed my signature as requested 

I had a front end knocking over rough roads at lower speeds so changed out the coffin arms and tuning forks on both sides with Spyder Performance ( not poly bush)  …..the old ones had to be cut out.

After a long test drive today of around 50 miles, the knocking is still there and as disappointingly the ride has become quite harsh with internal rattles that were not there before the suspension refresh.

1) What else could be the reason for the knocking at low speed?

2) Will the Spyder components settle down at all?

Just standard halogens….it’s not damp under the seat.

Ill try the light switch and see if that cures it

Symptoms are …

1) No headlights 

2) Sidelights only

3) Full beam won’t stay on but will flash

4] All bulbs ok

5) All fuses are ok

6) fog lights work

Is this a new headlight switch?
