First Gear Hammering / Clunking in 66 BB
HI--
This topic has been discussed before and I have searched the archives for a "Definitive" answer with no luck so -- with advance apologies here is the issue (again):
I have a low mileage 66 big block coupe --- runs and drives like a top -- no issues at all --
Took it out for a drive Sunday and pulled onto the street --- started in first gear and pulled away smoothly --- upon full release of the clutch and moderate acceleration I get a VERY LOUD heavy hammering sound---
I stopped and put the car in reverse and moved it back to the driveway --- went forward again and the same thing -- no hammering in reverse or upon turning into the driveway (hard right turn) --
This has popped up "over-night" so to speak --- no advance warning --- the car was smooth and powerful one day and now the hammering / clunking ---
So ---some questions:
1) Has anyone experienced this exact issue?
2) If so --- what did you do to alleviate the issue?
I have suggestions to check all of the U-joints and possibly replace them-- front and rear main -- left and right half shafts --
Check for a missing weight on the drive shaft --
Check for deterioration of the large rubber washer on the differential mounting ---
Check the sway bars front and rear ---
3) Did I miss anything? --- Has anyone had this issue and if so how did you solve it?
Thanks in advance for your insight --
Bill
