VIBRATION - DRIVELINE - DIAGNOSIS AND SERVICING
MERKUR 1985-86 XR4Ti
This article provides instructions for aligning and centering the (two-piece) driveshaft to resolve a driveline vibration as described below.
1.
A severe but temporary driveline vibration after the vehicle has been parked in extreme cold temperatures for an extended period. This symptom
will go away after 3 to 4 miles of driving but will recur when the vehicle is again parked in extreme cold for an extended period.
2.
Driveline vibration that is much less severe than condition 1, but can be felt in the floor of the car after the vehicle is warm (or in ambient
temperatures above freezing). This driveline vibration is most often felt when driving away from a full stop but on some vehicles can be felt at
highway speeds.
Driveline vibration in both driving conditions is caused by improper driveline alignment.
NOTE:
Driveline alignment on the XR4Ti is measured at the rubber joint/damper (guibo joint) at the front of the driveshaft. Any misalignment is
measured as runout at the guibo joint.
