My mechanic says it is the housing and asked if anyone knew of a repair kit or if we were going to have to get a different housing. I thought that maybe there was an oversize kit available for this problem. Is there a new housing available somewhere?

The HOUSINGS (respectively) are pretty much interchangeable from 1973-1993, so they should be fairly easy to find. Heck, if you shop around, you can probably find one that already has the proper gears in it. Dana 44's are very common, as where a 60F will be harder to find, and more $$$$ Last edited by 440trk; 02/09/14 04:33 AM.

Dana 44's are very common, as where a 60F will be harder to find, and more $$$$ I would use a differential out of a 75-93 model. On the earlier divorced transfer case trucks, the pinion angle points farther down, increasing the drive line angle. Just find a unit that has the same gears, and swap it. If you find a locking hub model, you can swap your stuff from the ball joints out. I wouldn't recommend keeping the full time junk, but the part time has a different wheel bolt pattern A 3/4 ton dana 44 will work just as well, but you will have to swap everything from the ball joints out, and 4.10 gears are most common. The full time stuff commonly has 3.55. Good luck. Last edited by viperblue72; 02/09/14 09:04 AM.

The problem was due to lack of grease the steering knuckles would wear out and just replacing the bearing and retainer kit would not always solve the problem. The big hole in the knuckle would wear just enough that the wheel would still wobble if axle was supported by a floor jack. Solution is to find a knuckle that is not worn out so bad.
