Reply To: Long threatened Worm Gear axle rebuild

[Gregory Long]

Hi Bill, take your bull gear, and your worm gear, and place them against each other as they would be in the differential housing.

From the photo, your rust pit is near the end or begining of the worm, And it looks like the worm contacts the bull gear only in the center of the worm.

I’m just ‘estimating’ but it looks like that rust spot would never touch a tooth on the bull gear.

I’d take a look at it either in an approximate postion, or put it loosely back in the diff housing and see where the bull gear and worm gear intersect.

Best of luck.
