Had the tail shaft off and taken to G&J DRIVELINE to change universal joint, carrier bearing, rubber boot between the 2 shaft and a re-balance today. Evo 3 gsr.
The issue was vibration noise on deceleration. Gears also crunch a bit on 2nd and 3rd. The outcome was gear don't crunch anymore. Car vibrates less, much much less. I still have to change carrier bearing mounting bushes as when I took them off I notice they were very worn. Also notice the plastic spacer on 1 side of the mounting bushes were missing. I supplied the parts and G&J driveline only charged me $150. New genuine carrier bearing were only $60+ gst. UNi joints were only $17 each.
Carrier Bearing Mounting bushes are on order from Torque solution. Only $50.
