SYMPTOM/CONDITION
A "clunk" or "squawk" when shifting from park into reverse, or neutral into reverse, on subject model vehicles built prior to September 1, 1986, should be diagnosed using the following procedures.
DIAGNOSIS
1. With engine off, place transmission in neutral and apply parking brake.
2. Raise vehicle on hoist.
3. Grasp prop shaft and rotate as far as possible in either direction. Hold in this position.
4. Using chalk or a crayon, mark a line across the pinion flange and the edge of the axle housing.
5. Rotate shaft in opposite direction as far as possible. Hold in this position.
6. Make a second mark on the axle housing opposite the mark on the pinion flange.
7. Measure distance between marks on axle housing.
8. If distance between marks is greater than 1/4", refer to appropriate service manual to correct rear axle backlash, and retest for "clunk" or "squawk."
9. If distance between marks is less than 1/4" or "clunk" or "squawk" remains after backlash correction, replace components as required using the following chart.
