Flywheel making the same noise it was making before the replacements?

Hi,

When you try starting the vehicle, what kind of noise do you hear? Is it a grinding noise or something different?

As far as the flywheel, you are correct. It goes on one way.

Now, I would suggest checking the teeth on the flywheel to make sure they are in good condition and not rounded off. If they appear good, then remove the starter and have it bench tested to confirm the Bendix is kicking the drive gear out to make contact with the flywheel.

If possible, record what it is doing and upload it for me to hear.

Let me know what you find.

I would make sure you have the correct starter motor, they have many different variations, next the starter shouldn't need shims, I would get a high-quality starter and like joe says inspect the flexplace teeth. Here is a generic guide and the instructions for your car in the images below:

A clashing or grinding condition may exist due to improper engagement of the starter to flexplate on some 1987-88 models equipped with 4.3L/V6-262, 5.0L/V8-305 and 5.7L/V8-350 engines with automatic transmission.

To correct this condition, replace the starter drive assembly, with new drive assembly P/N 10456422, which utilizes a stiffer jump spring allowing for proper engagement. During starter drive assembly replacement, all ring gear teeth should be inspected. If three or more consecutive teeth are damaged, the flexplate should be replaced. Use flexplate No. 10128414.

1. Disconnect battery ground cable.
2. Raise and support vehicle.
3. Remove starter to engine brace and heat shields, if equipped.
4. Remove starter mounting bolts and lower starter.
5. Disconnect wires from solenoids, then remove starter from vehicle.
6. Reverse procedure to install.

Here is the part number of the starter you need.

ACDelco part number 337-1022
