Hyundai Equus: Propeller Shaft Repair procedures

Inspection

CV Joint and Boots

1.	Shift the transaxle to Neutral.

2.	Raise the vehicle off the ground, and support it with safety stands in the proper locations.

3.	Check the center bearing (A) for excessives play or rattle and rubber for rent. If the center bearing has excessive play or rattle and rubber has rent, replace the propeller shaft assembly.

Inspect flexible coupling

1.	Check the front and rear flexible couplings for cracks or damage.

2.	Inspect the flexible coupling centering bushing. If the busing is damaged, replace the propel shaft assembly.

Propeller shaft runout

1.	Install a dial indicator with its needle on the center of front propeller shaft or rear propeller shaft.

Turn the propeller shaft slowly and check the runout. Repeat this procedure for the other propeller shaft.

Front Propeller Shaft Runout : 0.3mm (0.012in.)

Universal joint inspect

1.	Check that the spider berring rotates smoothly.

2.	Check that there is no play in the spider bearing if necessary, replace the propel shaft.

Replacement

loosen the muffler mount nut and then remove the muffler (A).

Tightening torque :

40.0 ~ 60.0 Nm (4.0 ~ 6.0 kgf.m, 28.9 ~ 43.3 lb-ft)

Tightening torque :

40.0 ~ 60.0 Nm (4.0 ~ 6.0 kgf.m, 28.9 ~ 43.3 lb-ft)

2.	Loosen the mounting bolts and then remove the bracket (A).

Loosen the mount bolts and then aluminum cover (A).

Tightening torque :

5.0 ~ 8.0 Nm (0.5 ~ 0.8 kgf.m, 3.6 ~ 5.7 lb-ft)

Remove the center bearing bracket (A) mounting bolts.

Tightening torque :

50.0 ~ 65.0 Nm (5.0 ~ 6.5 kgf.m, 36.1 ~ 47.0 lb-ft)

After making a match mark (C) on the rubber coupling (A) and rear differential companion (B), remove the propeller shaft mounting bolts (D).

Tightening torque :

90.0 ~ 110.0 Nm (9.0 ~ 11.0 kgf.m, 65.0 ~ 79.5 lb-ft)

Tightening torque :

90.0 ~ 110.0 Nm (9.0 ~ 11.0 kgf.m, 65.0 ~ 79.5 lb-ft)

1.	When retightening the propeller shaft mounting bolts after removing them, each bolt and washer must be placed in its original position and bolt insertion direction must be the same as before, so make marks not to allow the bolts and washers to be mixed up before removing the propeller shaft.

2.	If the position and direction of the propeller shaft mounting bolts and washers are reversed, it may caus]e vibration and noise at high vehicle speeds due to imbalance in the propeller shaft.

3.	If abnormal vibration and noise occur at high vehicle speeds after replacing propeller shaft with new one, balance the propeller shaft with a balancing machine.

6.	Installation is the reverse order of removal.
