94 tracker pntydrpr Posted April 12, 2017 Share Posted April 12, 2017 Hi guys and gals...New to forum. Looking to diagnose a whining noise in my 94 tracker 5 sp. 4x4 138k. It seems to make whining noise (almost like it has a mild cam) when sitting idling with clutch out...By out I mean not pressed. When I press down on clutch it goes away. No noticeable noice when driving but it is a ragtop and rather noisy from wind. Any suggestions on diagnosis? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Administrators Moses Ludel Posted April 12, 2017 Administrators Share Posted April 12, 2017 This sounds like the front/input bearing of the transmission. It might be the clutch throw-out bearing, as depressing the pedal will sometimes stop a release bearing noise. A bad throw-out bearing would be easy to diagnose with the transmission removed. This bearing is replaced routinely with a clutch replacement. This noise and the clutch pedal position rules out the crankshaft pilot bearing. A bad pilot bearing whines when the clutch pedal is depressed with the transmission in a gear and not neutral. You describe a condition with the transmission in neutral. Before condemning the transmission input gear bearing, make sure the transmission gear lube is not low...Inspect the lube quality and level.
