I've just returned from the dealer where I had the recall performed on my Mazdaspeed3 for the #4 Motor Mount. It was the first installation of the recall that my dealer (Mazda Direct, Columbus Ohio) had completed. I asked some questions and here are the responses I got.
The bolt is being replaced on all Speed 3's that were built within the specified production dates of the recall. The new bolt is slightly longer and has an integrated lock washer to keep it from backing out. The old bolt had a torque spec of around 40 ft/lbs. The new bolt is put in at around 120 ft/lbs.
When they do the inspection on the old bolt they put a torque wrench on it and check it to 22.1 ft lbs before removing it. If the old bolt is not at least that tight then they replace the #4 engine mount bracket too, as they figure it may be damaged. If the car iwas made before a certain VIN number then some rubber must be removed from the top of the existing motor mount.
Most of this information is a rehash of what has been posted before, especially the PDF's of the recall procedure that have been posted. What I didn't see anywhere was the large difference in the torque figures for the bolt.
My bolt was not loose and my original bracket was OK. I didn't expect to notice any difference in the car after having the recall completed, however I am pleasantly surprised to find that the engine rocks around less than previously. I already have the lower urethane mount installed (it's not really so much a motor mount as an anti-rotation device) and between the new bolt and the lower "mount" the motor barley moves at all. At first I thought I was imagining the difference, so I started playing with the car, giving it some hard gas and letting off, declerating against the motor and then hitting the gas hard. It's different and actually much better. The way the car should have been in the first place. I'm interested if it made a difference in anyone elses car.
Also I'm super releived that I don't have to worry about getting asphault rash on my oil pan anymore!
