Please call for customer service and availability at 1-800-886-2815. If the bearing surface of the outer race is grayish and pitted, it is trashed. I've seen the way the tech's do it, they are on the clock, so they simply reimpact the yoke nut down without taking pre or post rotational torque measurements. The Ford is renowned by drag racers for great strength--torque capacity greater than the Dana 60 with proper beefing up--with moderate weight about like that of the 12-bolt Chevy. Bearing extraction was done with the bearing separator and an impact wrench on the press bolt.
If you are familiar with working on rear axles, you can check the preload on the side bearings, too. If you have any questions about these or any other tools, get in touch with the pros at Complete Offroad. It only comes with the parts pictured. Remember, as with motor oil, half the function is to carry away heat. Drive end features pin retention hole and groove.
Just be prepared--I put a long bolt in the lower carrier cap holes--so it doesn't fall out on the ground once started. This information is not intended as an offer to sell, or the solicitation of an offer to buy, a franchise. The crush sleeve method is a factory short-cut that allows assembling the differential once and getting it right by simply tightening the pinion nut until the preload is correct. Includes: Carrier Bearings and Races, Pinion Bearings and Races, Pinion Seal, Complete Shim Kit, Ring Gear Bolts, Pinion Nut, Crush Sleeve, Oil Baffles, Slingers. Sorry for my delayed response. Pinion depth can be set by comparing the etched numbers on the head of the new pinion to those on the original pinion and changing shims per factory Service Manual. We were pretty relieved, and the rest, you already know.

If expedited shipping is selected the item will be shipped once it is available. Depending on the amount of heat such as, from towing or very high speeds and the ambient humidity, good intervals could be anywhere from 12,000 to 36,000 miles. If you want a longer one we can make it for you.
The rear end, with Limited Slip, wasn't too bad, but like mentioned in other posts, you do need a lot of special tools. I don't know how many times I repeated to Chris that without air, this job would be nearly impossible. The thick gear carrier accepts 3. Axle and drive line install was a breeze. Coast pattern is closer to centered under manual rotation, when pinion depth and backlash are correct. His experience with some of the tools was quite useful, however.
Now for some maintenance suggestions. If anyone needs the factory procedure for replacing their leaking pinion seal, you can e-mail me direct. It's a lot of work, with heavy, sometimes dangerous tools and equipment. Used to spread the axle housing for carrier assembly removal and installation on all Dana Model axles. It must be purchased seperately. If this is a project you plan to attempt, look me up, and I'll give you some more tips and jig building info that proved to be invaluable to me. However, let me elaborate so the installer will understand better whether this short-cut is working properly on that particular differential.
It took three more times to get the correct pattern and backlash. The changes in shimming are to compensate for different relative positions of the ring gear to the bearings, and different distances between the bearings. Torque the pinion nut to 250 lb-ft using a tool to prevent the yoke from turning note: an impact wrench capable of generating 300 lb-ft will do the job without the holding tool. He is a trained mechanic and had performed gear changes during mechanic's school. Whenever I replace a brake seal, I smear a bit of moly wheel bearing grease or moly camshaft lube on the lip and bearing surfaces to help the seal break in without burning up.
His experience proved invaluable in setting up the rear end. You may remember that many years ago bevel and spiral bevel gear types used in antique cars did not require this careful setting of clearances and spacing. So the load contact pattern doesn't run off the outside edge under load, you must set the very light manually applied load pattern to the inside half of the tooth. Pros need only one day. We kept the length down to save on shipping costs and so it fits better in a tool box. .
It should be pointed out that hypoid gears such as used by the Danas and other modern differentials are stronger and allow a lower floor pan because the pinion gear is well below the centerline of the ring gear. He had never done one on a real vehicle, just mockup rearends. After all this, it should be clear I hope that changing the carrier, such as installing a Detroit Locker, entails resetting the carrier bearing side bearing shims to obtain the correct preload and backlash. Two carriers are used for the Dana 60. Includes: Carrier Bearings and Races, Pinion Bearings and Races, Pinion Seal, Complete Shim Kit, Ring Gear Bolts, Pinion Nut, Crush Sleeve, Oil Baffles, Slingers.
But now, I know its not an impossible job, and one that with patience and some decent planning can be accomplished by a shmuck like myself. The Dana axles lubricate the bearings and gears by splash, including the outer bearings at the brake hubs. Thankfully after looking around I found the perfect supplies to make this special tool. It does take time to do this, but the result is a setup bearing that is easy to work with and doesn't stress the parts. Not to mention having the pride of knowing that you made it.
