Signs yours is due

• OMC Cobra clutch-dog U-joint bellow is cracked, split, or grease-caked — stamped 3854127 / 987467 / 18-2765 when readable.
• Water or grease weeps at the U-joint boot while exhaust and shift-cable bellows still look serviceable.
• You almost ordered exhaust 3850426 or AQ 876294 because the chart only said "bellow" — stop and match 3854127 on the U-joint path.
• Divert: older 987467-primary CSKU → GH 17B1009. Exhaust → GH 17B1010. Shift → GH 18B1001.

Will it fit my drive?

FAQ

Is 18B1002 the same as 18B5002?

Both can list OEM 3854127. This page is CSKU 18B1002 — match the CSKU / package you stock. Do not assume every 3854127 title is the same warehouse carton.

Is this the same as 17B1009 (987467)?

Related U-joint family, different primary identity. 17B1009 leads with 987467 for the Cobra clutch-dog era. 18B1002 leads with 3854127. Match the number on your old bellow.

Will this fit Volvo SX from a 1994–current year tag?

No open free pass. SX / DP-S is EPC-gated only on this page.

I saw AQ 875512 / 875827 on an old marketplace title — is that this?

No. Dual-table truth for 18B1002 is the 3854127 U-joint bellow. AQ drive bellows are a different path — do not order from a wrong marketplace title.

Do kit photos mean bearings and gaskets ship in the box?

No. BOM here is 1 × U-joint bellow (+ clamps only if your package shows them). Kit gallery images are contamination.

Is 47-2765 this bellow?

Do not buy on "2765" digits alone. Match 3854127 / 18-2765 / 89200.
