I have searched and it appears this has been a common issue. It doesnt appear however that the issue was ever remedied. The driveshaft was completely rebuilt, the rear end is all new with ingall control arms, jays rear toe elmimator etc. The rear end is a lsd 4 bolt with 90k on it. The noise only exists when im decelerating in any gear. When the clutch is depressed the noise goes away. Its sounds like a thud thud thud ....thud thud thud. Ive tried adjusting the driveshaft angle with no luck. The clutch is a act 2600 with a act flywheel. Bul fab mustache bar. On one hand people say drivetrain harmonics, others say backlash. Does this happen to everyone with these mods? Has anyone fixed the issue?
