All 1994-96 626 & MX-6 1-4 (2.0L) automatic transaxle vehicles.
DESCRIPTION
A clicking / clunking noise accompanied by vibration may come from the engine area while turning right and accelerating. The noise may be due to misaligned No. 1 engine mount.
Customers complaining of this concern should have the engine mounts inspected and repaired according to this bulletin.
NOTE:
^ This noise is similar to and may be confused with an internal transaxle concern or drive axle vibration.
^ This repair does not require mount replacement.
INSPECTION PROCEDURE
1. Verify the customer complaint.
2. Inspect the torque of all engine mount bolts (bracket and rubber bushing bolts).
NOTE:
