How can I verify that 48770-30090 is a genuine Toyota part?
A genuine Rear Upper Swing Arm (Right Front) shows the Toyota number 48770-30090 on the box label with the country-of-origin marking. On the part itself, the metal carries the supplier’s mark cast or stamped next to Toyota’s own mark, not a separate printed sticker; and the casting carries a raised maker mark (AISIN / TOYOTA / TEQ) with a small raised circle beside it giving the casting month and year. Documentation is available on request – commercial invoice, packing list and Certificate of Origin.
Is 48770-30090 a front or rear part?
This part is listed for the Rear Upper Right (No.1) position.
How many pieces are needed for 48770-30090?
You get one piece per position – check the quantity required for your application.
Is the genuine part worth it compared with an aftermarket equivalent?
The genuine part differs in ways that show up in service: the OE heat treatment and surface finish help the part resist wear, corrosion and seizing, and the part is machined to OE tolerance, so it mounts and seats without shimming or rework. These are the aftermarket equivalents you may also see quoted.
What documentation comes with an order?
Commercial invoice and packing list accompany every shipment, and a Certificate of Origin can be issued on request; the part number is die-stamped or laser-etched into the metal, so you can match it against the invoice.
