Product Name: Drive Shaft Center Support Bearing With Pressurized Oil Cup , Transmission Shaft Hanger

Physically inspect the driveshaft center support bearing

Once you've properly diagnosed the problem and you're fairly certain that the cause is due to a worn out center support bearing, the next step is to physically inspect the part. This is a critical step where many DIY mechanics and even new ASE certified mechanics tend to skip. Before proceeding, ask yourself this simple question: "Without manually inspecting the part, how can I be 100 percent certain that it's the root cause of the symptoms I'm trying to solve?" With an internal engine component, this is very difficult to do without disassembling the motor. However, the center support bearing is exposed under the vehicle and easy to inspect.

Materials Needed:

Eye protection

Flashlight

Gloves

Piece of chalk or marker

Roller or creeper if the vehicle is not on a lift

Step 1: Put your gloves and eye protection on. You don't want to start grabbling or handling metal objects without protection for your hands.

• The top of the center support bearing may be sharp and cause serious cuts to hands, knuckles and fingers. Plus, there will be a tremendous amount of dirt, grime and debris under your vehicle. Since you'll be looking upward, it's likely that this debris will fall into your eyes. Although it's assumed that blood, sweat, and tears are needed to repair most vehicles, reduce the potential of blood and tears and think safety first.

Step 2: Roll underneath the vehicle to where the center support bearing is located. Once you have the proper safety equipment in place, you'll need to ensure the vehicle is secure on the lift.

Step 3: Locate the front and rear driveshaft(s). Find where these are located on your car.

Step 4: Locate the center attachment where both driveshafts meet. This is the center support bearing housing.

Step 5: Grab the front driveshaft and attempt to "shake it" near the center support bearing. If the drive shaft shakes or appears loose inside the bearing, the center support bearing needs to be replaced.

• If the driveshaft is solidly mounted in the bearing, you've got a different problem. Complete the same physical inspection with the rear driveshaft and verify the loose bearing.

Step 6: Mark the alignment of both front and rear driveshaft. The two driveshaft's that attach in the center support bearings are attached on opposite sides of the vehicle as well.

• The front drive shaft is attached to the output shaft coming out of the transmission, while the rear driveshaft's propeller shaft is attached to the yoke that comes out of the rear axle differential.

• Warning: As noted above, the driveshaft is carefully balanced and needs to be removed in order to replace the center support bearing. Failure to reattach the driveshaft on front and back, precisely where they came from will result in an unbalanced driveshaft that will vibrate and may cause serious damage to the transmission or rear end gears.

Step 7: Locate where the front driveshaft attaches to the transmission. Using your chalk or marker, draw a solid line directly underneath the transmission output shaft and align that line to a similar line drawn on the front of the driveshaft.

Driveshafts that are connected into a splined shaft on the transmission can only fit in one direction, but it's still recommended to mark both ends for consistency.

Step 8: Make the same reference markings. Locate where the rear driveshaft attaches to the rear end yoke and complete the same reference markings as shown in the image above.
