In Reply to: Noisy Water Pump? (more) (long) posted by rIChie on December 07, 2001 at 12:36:17:
I usually start the car and let it warm up before I take off in the A.M. Though I've heard an obnoxious swooshing sound towards the front of the engine for a while when it's warm, it's getting a lot louder. I tried to convince myself that it was the alternator's bearings but after getting right in front of the fan blade and listening it sounds like something's loose in back of there. How can I further diagnose this water pump?.. How hard is the install?. I am not noticing any leakage of coolant..
How can I replace my center bearing? I feel a rubbing sound when I drive and the car is cold..
Thanks in advance...
Check the water pump by removing the belt and trying to shake the fan. If there is any play at all, the water pump is on its way out.
To change the driveshaft center bearing:
1)Remove the exhaust and the aluminum shield over the tunnel.
2)Using the parking brake to hold the driveshaft, remove the 3 bolts holding the flex disk to the driveshaft. Loosen the coupling sleeve holding the two halves of the driveshaft together (splined coupling). Then remove the 4 bolts holding the driveshaft to the differential.
3)While holding up the center of the driveshaft, remove the 2 bolts holding the center mount to the body.
4)Allowing the center of the driveshaft to drop down, CAREFULLY slide the front of the driveshaft off the transmission. Take care that the back end of the driveshaft doesn`t rest on the gas tank connector pipe.
5)Bring the driveshaft forward to clear the rear subframe and remove.
6)Before separating the two halves of the driveshaft, make sure they are marked so that they can be reassembled in the same alignment.
7)After separating the driveshaft, remove the circlip holding the bearing to the shaft.
8)Tap off the bearing with a soft hammer.
9)Install the new bearing by tapping the INNER race ONLY. A length of tubing or pipe of the appropriate size will work.
10)Installation is the reverse of removal.
