Hello Group, and thank you for any advice on this problem.
My 1990 G30 van (350 v8, auto) has a rattling noise which happens at idle (but only in Drive and Reverse), and when driving between certain speeds. Noise happens between 45-55mph, 60-65mph, and sometimes under acceleration at any speed. I've reproduce the noise while idling in Drive, wheels chalked and parking brake on, removed the instrument cluster and felt around behind it for anything that might effect the rattling noise. No luck. The only thing that effects the rattle when idling in Drive is turning the steering wheel...most of the time. I'm wondering if the harmonic balancer might be failing, or if there is something loose within the steering column...
Any thoughts on this appreciated!
