I have a GMC K1500 1996 5.7L Manual 4WD
NV3500 transmission with 230k miles on it had a loud squeal when the clutch released, suggesting a release bearing. Replaced release bearing – clutch is about 2 years old – noise is still there. What else could cause the noise symptoms of a release bearing? Should I replace the clutch, pressure plate and flywheel – or is this indicative of internal bearings on the tranny. Can you help?
Based on our experience the problem (loud squeal) you describe is typically caused by failure input bearing. With the mileage over 200k we would suggest that its time for new bearings, gaskets, seals and syncro ring.
