i recieve ssdi. i worked for gm thirty years ago and am now eligible to cash out my retirement. the value is 36k. how will this effect my ssdi income?

SSDI -- correctly called Disability Insurance Benefits (DIB) -- is not impacted by your asserts or passive income. At age 65, DIB converts to regualr SS retirement. There should not be any issues with the payout. If you are on Supplemental Security Income (SSI), then there would be a diisqualification issue pending spending down the payout.
