How to Fix a Noisy Crank & Rod Bearing

The crank and rod bearings in the engine of your car are prone to a lot of wear, and when they become noisy, the best thing to do is to replace the rod bearings. The rod bearings wear out just like any other engine part through constant use. They help the engine by ensuring the rods operate smoothly around the crankshaft. They are located on the front of the engine. The connecting rod is clearly visible when you pop the hood and the bearings are located on the rod. While this job may be time consuming, it is the only way to permanently fix the problem.

Instructions

1

Pop the hood of the car and turn on the engine. Allow it to run for a few minutes and locate the noisy crank and rod bearings. The connecting rod will be clearly visible without having to remove anything to find it. Turn off the car and let it cool down before proceeding.

2

Remove the bolts holding the connecting rod in place. Match up the bolts with the proper size socket wrench and loosen them from one end of the connecting rod. Pull out the pins on the other end of the connecting rod to loosen it completely.

3

Slide the old bearings out from the connecting rod, tapping them lightly with a hammer, if necessary, to loosen them. Clean the surface where the rod bearings were removed with a rag. Wipe down the area and add degreaser to the rag to further remove oil from the surface.

4

Slide the new bearings onto the rod, setting them exactly where the old ones were located. Continue sliding all of the new bearings back onto the cleaned connecting rod until the set up is back to the original configuration.

5

Clean off the bolts and pin with a clean rag. Tighten the bolts back into place with the socket wrench. Continue tightening each bolt until it can not be turned any more. Pop the pins back into place. Close the hood and test the engine to make sure the noise is gone.
