Purchased a 2006 Tundra 4.7 Auto. Trans. TRD package, towing package.
How can I find out if it has Limited Slip Differential. Door sticker has C/TR
1E3/FD 12 UCK 30 L ARBSKA A/TM A01B/A750E 724 I know these have
something to do with the Chassis #'s Can Anyone help?

That should be a limited slip. Most vehicles built after 2000 are limited slip differentials and require synthetic fluid for the rear pumpkin. hope that helps.

Thanks for the info. I found a sticker on the differential (LSD).
