Step-6: Place Differential Case over Ring Gear Place some red thread sealant in the ring gear bolt holes. I've had some that were broken beyond the last threads so they could be pulled with a magnet after the bolt was out. Most often, during axle shaft bearing or seal replacement service, the bolt snaps as you try to remove it. It is partially installed here; you want to chase the O-ring into the groove all the way around. If the pattern needs to be adjusted, remove the differential, adjust the pinion cartridge shim, and reset the ring gear backlash. This is another reason to use a new nut each time.
Make sure that the spline is engaged in the differential side gear. It sucks when a simple job ends up like that. The removal of this lock bolt is essential in performing rear axle , rear axle bearing , rear axle seal, most differential repairs, as well as all differential overhauls and rebuilding. This time saving Extractor Kit made by Fabbri Associates, Prototype Tool and Development. Be very careful to make sure that the cap lines up with the adjuster nut threads and tighten the bolts in place. If you have one, please share it.
The retainers keep the bearings and axle shafts from sliding out of the axle housing, and the axle shafts with bearings are a snug fit into the axle tube ends. These bolts hold the brake backing plate and axle retainer plate in place right. This in turn flexes or, in effect, bends this lock bolt back and forth causing it to fatigue and break. From axle seals to complete overhaul this bolt must be removed. A Dremel with a flex shaft might help. .
I really can't even imagine being able to drill that thing out well enough to where you'd be able to preserve the threads and I doubt a Helicoil would be an ideal solution for that location. The bolt in my axle came out very easily with only the use of a hooked scribe pen. Most of the time, the original copper washers are long gone but you do want a soft material under these nuts left. This Tech Tip is From the Full Book,. Here you see my homemade tool, but similar production tools are also available. I got fairly lucky the way it broke. Like I noted, the crosspin will hit the ring gear on the way out but the half that is near the lockbolt is flat on one side of the shaft so it clears the ring gear.
Step-25: Install Differential Unit Flip the gear case and set the races in place between the threaded portion of the gear case. Some products are for show or restoration use only. Step-7: Install Ring Gear By hand, pull the ring gear into position and install a couple of bolts. Repeat this procedure for the opposite side. You can achieve the same arrangement with a socket on the bottom side of the axle shaft and using a hammer to seat the stud. Step-6: Inspect Axle Shaft The finished axle shaft with the studs in place should look like this. The tapered-roller, big-bearing style is not sealed but shares the oil with the axle.
Is there any other place where i should put loctite on the rear diff??? Then a set of fixtures is installed on the wheel-end side of the housing, along with the axle shafts. And since its not flatted on the other half, pushing the crosspin out only makes it strike the ring gear. Products may not be 'street' legal nor meet the legal labelling or instruction requirements. This is where you combine the assembled differential with the gear case and hypoid gears. Of course, the overall axle width, shock and spring brackets, and any other bracketry are all checked dimensionally and compared to the custom build sheet. Begin by starting two bolts that are opposite each other to hold the gear in place.
These bolts may need to be removed later to adjust the pinion cartridge shim. The rear axle could lock up and cause a severe loss of vehicle control and an accident. Is there any way you can rotate it? Set the drill on counter clockwise rotation and start drilling in the bolt. Step-19: Install Pinion Nut The last part to be installed is the pinion nut. My only concern was with getting little shavings thrown back into the differential where the pinion comes in. First snug them all in place, then torque to 20 ft-lbs, and finally to 40 ft-lbs.
You think between the two of them they would come up with a better bolt. Special Note: Safety recommendations require the use of safety goggles or other appropriate eye protection during the entire extracting procedure. One particular nut that possesses tremendous importance in a vehicle is the pinion shaft nut. I have another question: when i re-assembled the diff, i didn't take care on the bearing cap bolts, and i simply torque them to the specs, without putting loctite on them. These bolts are notorious for snapping during removal. Because they are T-shaped, they do not rotate when you tighten the nuts on the other side. With the head broke off, only the threads are holding it in, so if you can get in there with a small punch, you may be able to tap it in the out direction.
Step-4: Install Washers Torque Fasteners From the factory, copper washers were placed underneath the nuts for the third member. Just enough that i couldnt pull it out with a drill. How have others done it? A right angle drill and left hand drill bit would be my first try. I assume you mean the crosspin in the carrier? Shorten the bit as much as you can if needed. Once fully seated, the shaft should look like this right. I put to holes in the bolt at oposite sides of it. Often the differential pinion shaft lock bolt is found in a broken state when servicing this type of rear end.
