New Recall Notice today

If you install the crow's foot so the toes point in the direction you are pulling, then there is no change in length and you don't need to make any correction.

Thanks, James. I did a search and finally found located the formula for calculating the torque wrench reading in relation to the length of the crow's foot adapter. It wouldn't cut-and-paste but here is the link (hopefully!):
Torque Wrench Adapter Extended Calculation - Engineers Edge

Definitely need that special tool to check the torque.

The adapter isn't mickey mouse and cannot affect the reading if installed that way.

That adapter DOES affect the torque reading. Ford uses crowsfeet like these on injector lines and you must use basic math to reduce the amount of torque applied. Generally, it's reduced by 5-10% depending on the length of the TW and the length of the crowsfoot.

just received the Owner's Manual Supplement in the mail for the "Rear Wheel Alignment Adjustment"

[Rickl]

I received mine today. They provide a booklet to keep in your glove box, and you are asked to make sure your "Alignment Professional" reviews it before starting any work.

The booklet contains the torque specs for tightening the various fasteners (41 lbf).

The really interesting thing, is that the torques specified are when using a torque wrench with a fulcrum length of 345mm (1.13 ft) and a SST (22 mm crowfoot wrench).

There is also a page that explains how adding the extra length of the SST changes the actual torque being applied to the fastener and the 41lbf is only correct for the torque wrench and SST described in the book.

The book also says that the Recall will not only examine the vehicle but will be clipping labels to the various fasteners to remind future mechanics about these precautions.

Shouldn't you correct in the other direction? The crow's foot attachment increases your mechanical leverage therefore actual torque on the fastener will be greater than that indicated by the wrench.

Here is a copy of the new Owners Manual Supplement.

The actual recall letter says that a Toyota dealer will inspect the rear suspension arm #1, and , where necessary, replace it with a new one at NO COST to customers.

It says on page #3 of the supplement, that as part of the remedy Caution Labels are being installed to help notify technicians performing a rear wheel alignment, of the importance of proper tightening procedures. This step makes it necessary to bring your RAV in to the dealer even if you have never had any alignment work performed.

I e-mail my tire shop this PDF. He did not know about any recall and said they always get updates to the toque specs if there was any, yet I feel that they had none for this.

This is too new for them to have any updates. I will not do alignment adjustments in RAV4 until absolutely necessarily.
