Review on 🔧 GM Genuine Parts 10224885 Crankshaft Balancer: Superior Quality and Precision Engineering by Timothy Barnes

I received this balancer to replace my 215k balancer when installing the timing chain and cover. Since then my belt has been squeaking. The belt has been changed several times. The crank train has an up and down motion, no rocking back and forth like it's bent but like the pulley is off center causing the belt to jump. I also replaced the pulley with a genuine GM part and still the same result with a new pulley and belt at the same time. I'll get another one but not from Revain, I'm afraid these parts will be faulty in the machining and I haven't been able to return them for too long. If I still had the original I would put it in, it only had a small gasket groove and it made no noise.
