Last time I had to replace the seals, the axels were "mic'ed" down the full length and found to be in-round.

Two theories about the problem:
1. Bend housing is a definate because the problem is happening on both sides.
2. Toyota knows about this issue. It seems that the seal that rides up agaist the ABS is riding "too deep" and the back spacing is off. Sometimes as much as 3/8" more than factory specs. If the dealership/tech is competent the appropriate placement is usually accomplished with Machinist Marking Grease. Also the tension springs inside the inner seals are uaully shortened to provide increased sealing.

After speaking with techs who've dealt with this problem, the good news is that none of them have seen this issue on rear ends that have an E-Locker. They can't come up with a good reason why not. But, hell if replacing the rear end will cure the problem - then why not, plus I'll get the locker that I've been wanting.
