Alright guys Ive got the F&I managers '91 coupe in my bay and hes complaining of a knocking. Its your typical ZF gear rattle, no worse than any other one Ive ever heard, I already filled the trans with some Castrol TWS 10-60 and as expected it got marginally better. The owner however is completely....well concerned with this. Ive told him its normal, and not detremental but he doesnt like it. Wants it gone. I recommended a full tuneup(its a 91 with 51k miles and no service ever save for oil/air changes) and told him this would help an additional small amount.
My question is, have any of you ever replaced the dual mass flywheel? How long do these flywheels actually work for?? How loud was this gear rattle when the cars were new?
They stopped making them the year I started in the dealership and Ive never had to actually fix this problem before, usually the oil and "normal" explanation has been enough.
So whats the concensus on installing a new OE flywheel??
Thanks.
