innerware Posted August 29, 2003 Share Posted August 29, 2003 Hey all, I tried to search for cures of vibration but not many were found. I ahve a 78 280 still with the original motor and everything. I replaced my driveshaft with the one from motorsport auto(replacable u-joints) and replaced my tranny mount and diff mount. I thought this would stop my car from vibrating. It didn't, Could I have installed the driveshaft wrong? Are there any other places to look for this problem. Could my flywheel be unbalanced? How do I tell if it is a tranny problem? It is a 4 speed. I notice the vibration at all speeds, but not as bad or at all when sitting idle. I don't have the clunk that I used to before I replaced the diff mount. That is good. What are the best ways to track this down? Thanks once again, Kyle Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted August 29, 2003 Share Posted August 29, 2003 Have you confirmed the driveshaft U-joints are lined up? I realize there is no slip joint that would allow this, but if it was fabricated poorly... What about your halfshaft U-joints? Your shocks? Your mustache bar bushings? Tires balanced, not flat-spotted? Quote Link to comment Share on other sites More sharing options...
