Below you will find answers to the most frequently asked questions we receive. If you have additional questions about crankshafts, please contact us. We will do our best to answer any questions you may have, even though we may not be able to visually inspect the engine component at that time.

Frequently Asked Questions About Crankshafts

My engine is making a "knocking" sound. Did I "spin" a crank bearing?

It is possible that a bearing has failed. However, a bad piston pin can also make similar knocking sounds. I would advise taking your vehicle to an ASE Certifed repair center for diagnosis.

How much does it cost to grind a crankshaft?

Generally, the cost is about $10 per journal for a standard passenger car crankshaft. Industrial crankshafts with a larger radius cost more.

How do you straighten a "bent" crankshaft?

Crankshafts that have a minimal out of round are "stress relieved." We do not bend the crankshaft again in an effort to counter out of round as this adds additional stress to the crankshaft. Crankshafts that have an excessive bend should be replaced, and we will let you know if we encounter this during our initial inspection.

My crankshaft has a lot of "end play." What is the problem?

Chances are your thrust bearing has failed. This could require a thrust weld on the crankshaft to complete the repair.

Will you rebuild my engine?

At the present time we do not remove and replace engines. We also do not assemble short blocks or long blocks. However, as ASE Certified Engine Machinist's we do the majority of machine work for engine rebuilders of all skill levels.
