Replacement time harmonic balancer 1994 olds 98

You would need to use a puller. Looks like a chicken foot on steroids.

A harmonic balancer puller-cheap and easy to use-available at any auto parts store. The hardest part is getting the crankshaft pulley bolt loose. An impact tool is best, but not absolutely necessary. Old school way: not recommended, but I've done it this way: put a socket and long stout breaker bar on the crank bolt. Let the breaker bar end rest on the ground. Now use the starter to just bump the engine over one quick time-just one little bump is all it takes to loosen the crank bolt- if you positioned the breaker bar right. Good luck, Joe.

Its the harmonic balancer. The rubber in the balancer has disintegrated and not balancing the motor any longer. You have to install a new one.

Yes. Jack the car up securely. you need to take passenger wheel off.remove caliper off . remove rotor. remove shock assembly and wheel bearing assembly slide.axleshaft out of the way.take serpinetine belt off. remove cover so you can see and access harmonic balancer.use impact to take bolt out of harmonic balancer.use wheel puller to take off harmonic balancer. Crank sensor should be right under harmonic balancer.

you will need a special puller... our shop would charge about $100 labor

they usually go bad because the harmonic balancer is sliping.theres a rubber ring on outside of balancer that goes bad

Remove the crankshaft pulley,the harmonic balance,with a puller made for this,then you can replace the sensor,and align it,if it is not aligned,it will break it.

Replace the crank pulley aka. balancer, they fall apart and knock.

usually all crankshaft sensors are located right next to the main drive pulley (Harmonic balancer). As far as being easy is concerned some are not so easy as some require the removal of the harmonic balancer to get to it.. but you might be lucky Gm is pretty good at making the Crankshaft sensor accessible without removing the harmonic balancer.
