How much does it cost to repair a crankshaft pulley and harmonic balancer for a 2002 Mitsubishi Montero Sport V6 3.5L engine

there is a recall for that

I bought my 03 sport for 500$ because the balancer bolt broke. Took a week to find the part online from the east caost 20 min to tap out the broken bolt and one new a.c. belt total was less than 40$ and 5 hours of my time taking the radiator and fan off im no mechanic but it wasnt that hard to fix

Why do you have to replace them ? It's not common unless something broke like the crank pulley pinned sheared off. These parts are available at the dealers. The HB is available at Auto zone or ???? I prefer to go to pick a part and expose these parts and dismantle. It will cost about forty bucks compared to over 200 hundred at dealer, It is good practice to dismantle a pick a part car instead off destroying yours trying to learn a big project. i live in Orange County, CA and there are a lot of pick a part stores within 50 miles.
