More information about the Tacoma rear axle nut recall, the recall procedure at the dealer is as follows:
1. Remove each nut, do this one at a time so the axle does not move and damage the o-ring seal.
2. Once you have a nut removed check the surface of the nut and make sure it is flat, check the area on the axle end plate where the nut seats and make sure there is no weld splatter on the surface under the nut.
3. If you find weld splatter on the surface under the nut then take a file and file down the weld splatter so that it is a flat surface. If the nut has damage from the weld splatter then replace the nut.
4. I added this, when you replace the nut put a little bit of blue loctite on the stud threads and spin the nut back on. Torque the nut to 41 ft lbs. Repeat this with all eight of the nuts, four on each side. The blue loctite will keep the nuts from backing off from road vibration.
I saw a video of a Toyota mechanic doing this procedure but he failed to use any loctite. These nuts are not a locking style nut so I am puzzled as to why that Toyota mechanic did not use any loctite, it looks like Toyota used some kind of thread lock when the axle was assembled because the stud threads had a white substance on them like a thread lock of some kind.
Now here is where I don't think Toyota has been exactly honest, I down loaded a copy of a page from a Toyota Tacoma manual and that page shows the torque spec is 27 ft lbs of torque. But a Toyota mechanic says their shop manual is showing 33 ft lbs of torque. Now here is the real kicker and where I think the true problem is and that is the Toyota recall procedure for the dealers calls for torquing the nuts to 41 ft lbs of torque.
That is three different torque specs, I think what happened is Toyota called for to low of a torque spec and that contributed to the issue, the recall procedure is calling for almost 34% more torque on each nut than the page I downloaded from a Toyota manual and is 19% higher than the torque spec in the Toyota dealers shop manual the Toyota Mechanic stated.
